From 1a81561854bd112af3dd1890fe7ddc632149ee74 Mon Sep 17 00:00:00 2001 From: Guillaume Loulier Date: Mon, 6 Jul 2026 10:44:34 +0200 Subject: [PATCH 01/26] feat(windows-pe): Windows x86_64 PE32+ cross-compilation + random_bytes builtin Reconstruct PR #446's feature set on top of current main. Windows x86_64 PE target: - Platform::Windows with the MSx64 ABI (rcx/rdx/r8/r9, 32-byte shadow, 16-byte alignment) and ~40 Win32 shim wrappers converting SysV->MSx64 (WriteFile/ReadFile, sockets, file/dir ops, VirtualAlloc/Heap, BCryptGenRandom, ...). - Syscall->shim transform wired into the pipeline + runtime cache (Windows-only) so PE binaries contain no raw Linux syscalls; unmapped syscalls route to __rt_unsupported_syscall instead of a silent trap. - Entry wrapper (MSx64->SysV), MinGW-w64 assembler/linker, kernel32/msvcrt/winmm/ ws2_32/bcrypt/shlwapi link set. --target windows-x86_64 (alias x86_64-pc-windows-gnu); .exe / .dll outputs. CI windows-pe-cross-compile job (MinGW + Wine) wired into the gate. Fix the implicit end-of-main exit code on Windows: emit_exit and emit_exit_with_result_reg now load the code into edi and call the __rt_sys_exit (ExitProcess) shim directly, identical to an explicit exit($n), instead of returning through the MinGW CRT. The CRT's exit() reaches the same rdi-consuming shim, so the old return path left rdi holding leftover data and exited with a garbage nonzero code. random_bytes(int $length): string: - Cryptographically secure random byte string on every supported target (arc4random_buf / getrandom / BCryptGenRandom), fatal on entropy failure or a constant length below 1. - Expressed as a single-source registry home file (src/builtins/math/random_bytes.rs) instead of the legacy hand-maintained tables; excluded from the legacy runtime-callable wrapper as an EIR-only builtin. Builtin docs + registry JSON regenerated. Callable-invoker ABI on Windows x86_64: - The descriptor-based runtime callable invoker read its descriptor from a hardcoded rdi, but on Windows the caller passes it in the MSx64 first arg (rcx); read it from int_arg_reg_name(target, 0) instead. - The invoker clone helpers passed arguments to the __rt_array_clone_shallow / __rt_array_to_mixed / __rt_hash_clone_shallow / __rt_hash_to_mixed / __rt_array_new runtime helpers via int_arg_reg_name, which returns the target user-call ABI (rcx/rdx on Windows); those helpers use the System V AMD64 ABI on every x86_64 target and read rdi/rsi. Add runtime_int_arg_reg_name (SysV on all x86_64, platform ABI on AArch64) and route the four helper call sites through it. No-op on Linux and AArch64. --- .github/workflows/ci.yml | 101 + CHANGELOG.md | 2 + README.md | 7 +- ROADMAP.md | 2 + .../_internal/__elephc_gmmktime_raw.md | 2 +-

experimental Windows x86_64 (PE32+) cross-compilation target (`--target windows-x86_64`, alias `x86_64-pc-windows-gnu`): produces a GNU/MinGW-ABI `.exe` (`.dll` for `--emit cdylib`) via `x86_64-w64-mingw32-gcc`, and requires the MinGW-w64 cross toolchain on the host doing the build. Runtime shim coverage and end-to-end execution testing are still catching up to macOS/Linux, so treat it as cross-compilation support rather than a fully verified target. +- Add the `random_bytes(int $length): string` builtin: a cryptographically secure random byte string on every supported target (arc4random_buf / getrandom / BCryptGenRandom), fatal on entropy failure or a length below 1. - Int-backed enum `from()` / `tryFrom()` now accept a dynamically-typed (`mixed`) argument (issue #449): a `foreach` value over a heterogeneous array, an untyped parameter, etc. are coerced on their runtime type before the enum lookup — integer/numeric-string resolve (or throw `ValueError`), float truncates, bool/null coerce, and array/object/resource/closure throw `TypeError` naming the given type. Previously any `mixed` argument was rejected at compile time. Target-aware on every supported backend. - Int-backed enum `from()` / `tryFrom()` now accept a numeric string (issue #349): `Level::from("1")` coerces the string to the integer backing value (as a distinct EIR coercion lowered before the enum call) and returns the matching case, instead of being rejected at compile time. A numeric string with no matching case throws `ValueError`; a non-numeric string (e.g. `"x"`) throws `TypeError` with PHP's exact argument-type message — matching PHP's coercive typing on every supported target, including PHP-rejected libc `strtod` extensions such as hexadecimal `"0x1"`, `"INF"`, and `"NAN"`. - Fixed an enum `from()` / `tryFrom()` refcount bug (surfaced while fixing #349): the returned case singleton was under-retained, so storing the result into a reassigned variable inside a loop drove the persistent singleton's refcount to zero and freed it — producing garbage reads or a heap crash after a few iterations. `from()`/`tryFrom()` now retain the matched singleton, keeping it alive like direct case access.

Adds scripts/gen_windows_codegen_ allowlist.py to regenerate the lists from a full run, and drops 2 wine-flaky include_paths tests from the allow-list with retry tolerance. --- .config/nextest.toml | 9 + .github/workflows/ci.yml | 148 + docs/compiling/targets.md | 68 + scripts/gen_windows_codegen_allowlist.py | 336 ++ tests/codegen/support/compiler.rs | 3 + tests/codegen/support/platform.rs | 113 +- tests/codegen/support/projects.rs | 42 +- tests/codegen/support/runner.rs | 121 +- .../support/windows_codegen_allowlist.txt | 3137 +++++++++++++++++ .../windows_codegen_known_failures.txt | 1887 ++++++++++ tests/codegen/windows_pe.rs | 43 +- 11 files changed, 5834 insertions(+), 73 deletions(-) create mode 100755 scripts/gen_windows_codegen_allowlist.py create mode 100644 tests/codegen/support/windows_codegen_allowlist.txt create mode 100644 tests/codegen/support/windows_codegen_known_failures.txt diff --git a/.config/nextest.toml b/.config/nextest.toml index 640e47603b..f6d597b64d 100644 --- a/.config/nextest.toml +++ b/.config/nextest.toml @@ -35,6 +35,15 @@ relative-to = "target" path = "debug/libelephc_web.a" relative-to = "target" +# Emit a machine-readable JUnit report for every `--profile ci` run.

Target-aware path constants via the existing `PHP_OS` ConstRef precedent: `PHP_EOL`, `DIRECTORY_SEPARATOR`, `PATH_SEPARATOR` now resolve in `prescan::collect_constants` using new `Platform::php_eol()` / `directory_separator()` / `path_separator()` helpers (Windows: CRLF, "\\", ";"; elsewhere: LF, "/", ":"). macOS/Linux behavior is unchanged. `emit_shim_exit` prologue corrected to `sub rsp, 48` (N % 16 == 0) after `and rsp, -16` so WSACleanup and ExitProcess stay 16-byte aligned; a regression test locks the alignment invariant. --- src/codegen_support/platform/target.rs | 33 ++ .../platform/windows_transform.rs | 6 + src/codegen_support/prescan.rs | 25 +- src/codegen_support/runtime/win32/mod.rs | 310 +++++++++++++++++- src/lexer/literals/identifiers.rs | 1 + src/lexer/token.rs | 1 + src/name_resolver/names.rs | 5 +- src/parser/expr/prefix.rs | 15 +- src/parser/keyword_name.rs | 1 + src/types/checker/driver/init.rs | 3 + .../codegen/callables/constants_and_system.rs | 9 + tests/codegen/windows_pe.rs | 9 + tests/lexer_tests/constants.rs | 14 +- 13 files changed, 414 insertions(+), 18 deletions(-) diff --git a/src/codegen_support/platform/target.rs b/src/codegen_support/platform/target.rs index d605d8960e..229b5b024f 100644 --- a/src/codegen_support/platform/target.rs +++ b/src/codegen_support/platform/target.rs @@ -65,6 +65,39 @@ impl Platform { } } + /// Returns the PHP-compatible end-of-line sequence for this platform. + /// + /// Windows uses `"\r\n"` (CRLF); macOS and Linux use `"\n"` (LF), matching PHP's + /// `PHP_EOL` constant. + pub fn php_eol(&self) -> &'static str { + match self { + Platform::Windows => "\r\n", + Platform::MacOS | Platform::Linux => "\n", + } + } + + /// Returns the PHP-compatible directory separator for this platform. + /// + /// Windows uses `"\\"`; macOS and Linux use `"/"`, matching PHP's + /// `DIRECTORY_SEPARATOR` constant. + pub fn directory_separator(&self) -> &'static str { + match self { + Platform::Windows => "\\", + Platform::MacOS | Platform::Linux => "/", + } + } + + /// Returns the PHP-compatible `PATH_SEPARATOR` for this platform. + /// + /// Windows uses `";"` to separate entries in `include_path`/`PATH`-like lists; + /// macOS and Linux use `":"`, matching PHP's `PATH_SEPARATOR` constant. + pub fn path_separator(&self) -> &'static str { + match self { + Platform::Windows => ";", + Platform::MacOS | Platform::Linux => ":", + } + } + /// Returns the `O_WRONLY | O_CREAT | O_TRUNC` flag combination for `open()`. /// /// These flags open a file for writing, creating it if it does not exist, diff --git a/src/codegen_support/platform/windows_transform.rs b/src/codegen_support/platform/windows_transform.rs index 52f662c099..6ba5fbb208 100644 --- a/src/codegen_support/platform/windows_transform.rs +++ b/src/codegen_support/platform/windows_transform.rs @@ -37,6 +37,7 @@ fn linux_syscall_to_shim(linux_num: u32) -> Option<&'static str> { 12 => Some("__rt_sys_brk"), 16 => Some("__rt_sys_ioctl"), 20 => Some("__rt_sys_writev"), + 21 => Some("__rt_sys_access"), 28 => Some("__rt_sys_accept4"), 32 => Some("__rt_sys_dup2"), 33 => Some("__rt_sys_dup"), @@ -60,9 +61,11 @@ fn linux_syscall_to_shim(linux_num: u32) -> Option<&'static str> { 62 => Some("__rt_sys_kill"), 63 => Some("__rt_sys_uname"), 72 => Some("__rt_sys_fcntl"), + 77 => Some("__rt_sys_ftruncate"), 78 => Some("__rt_sys_getdents"), 79 => Some("__rt_sys_getcwd"), 80 => Some("__rt_sys_chdir"), + 82 => Some("__rt_sys_rename"), 83 => Some("__rt_sys_mkdir"), 84 => Some("__rt_sys_rmdir"), 85 => Some("__rt_sys_creat"), @@ -234,7 +237,10 @@ mod tests { assert_eq!(linux_syscall_to_shim(1), Some("__rt_sys_write")); assert_eq!(linux_syscall_to_shim(3), Some("__rt_sys_close")); assert_eq!(linux_syscall_to_shim(9), Some("__rt_sys_mmap")); + assert_eq!(linux_syscall_to_shim(21), Some("__rt_sys_access")); assert_eq!(linux_syscall_to_shim(60), Some("__rt_sys_exit")); + assert_eq!(linux_syscall_to_shim(77), Some("__rt_sys_ftruncate")); + assert_eq!(linux_syscall_to_shim(82), Some("__rt_sys_rename")); assert_eq!(linux_syscall_to_shim(999), None); } diff --git a/src/codegen_support/prescan.rs b/src/codegen_support/prescan.rs index b2e5957075..b34c5575cf 100644 --- a/src/codegen_support/prescan.rs +++ b/src/codegen_support/prescan.rs @@ -22,7 +22,9 @@ use crate::types::PhpType; /// Seeds the constant map with built-in PHP constants and user-defined constants. /// /// Built-in constants include platform-specific values (e.g., `FNM_*` flags differ -/// between macOS and Linux), `PATHINFO_*` bitmask values, stream handles (`STDIN`/`STDOUT`/`STDERR`), +/// between macOS and Linux), the target-aware path constants `PHP_OS`, `PHP_EOL`, +/// `DIRECTORY_SEPARATOR`, and `PATH_SEPARATOR` (which differ on Windows), +/// `PATHINFO_*` bitmask values, stream handles (`STDIN`/`STDOUT`/`STDERR`), /// `LOCK_*` values, array callback-mode constants, `JSON_*` integer constants, and /// `PREG_*` integer constants.

Surface the sysroot to both the production link (src/linker.rs) and the test harness (tests/codegen/support/runner.rs) via -L/lib added before the -l args, gated on ELEPHC_MINGW_SYSROOT (set in CI, unset on local non-CI builds so no missing-directory warnings). The external-C libs (-lpcre2-8 -lpcre2-posix -lbz2 -lz) were already pushed unconditionally by runtime_features.rs; they only needed a search path. Add require_windows_builtin_library mirroring the macOS helper, and use it for the convert.iconv.* stream filter so Windows emits -liconv (msvcrt ships no iconv), resolved by the cross-built libiconv.

Three pure helpers + unit tests cover the gating without env mutation. ci.yml: rustup target add x86_64-pc-windows-gnu in the windows-codegen- parity job; its bridge prebuild uses a new BRIDGE_CRATES_WINDOWS subset (image/pdo/crypto/tz) with --target + CC/AR/RANLIB env. elephc-phar (bzip2-sys system libbz2, ELF-only on the ubuntu host) and elephc-tls (ring asm) are excluded from the Windows prebuild so their C/cc-rs deps cannot block the job; on-demand ensure_bridge_staticlibs still attempts them per-fixture and nextest isolates any failure. macOS/Linux bridge steps keep $BRIDGE_CRATES with no --target.

The supported target matrix is currently `macos-aarch64`, `linux-aarch64`, and `linux-x86_64`, plus `windows-x86_64` as a newly added, experimental cross-compilation target (runtime shim coverage and end-to-end execution testing are not yet at parity with the other three).

New features, builtins, runtime helpers, optimizer assumptions that affect emitted code, ABI behavior, and ownership/GC paths must either support every supported target in the same change or clearly isolate an intentionally unsupported path with diagnostics, tests, and documentation. A feature is not considered done while any supported target has a missing runtime symbol, reduced semantics, stale documentation, or an untested target-specific lowering path.

Three latent ABI-mismatch classes silently corrupted args or misread returns on windows-x86_64 (invisible on the macOS/Linux CI, which never exercises the MSx64 boundary). This commit eradicates all three. Class 1 (~100 sites) — a bare `call ` from an x86_64 emitter resolved to an msvcrt/ws2_32/zlib/pcre2/iconv/bzip2 import entered with SysV registers. Introduce `Emitter::emit_call_c` (codegen_support/emit.rs): on windows-x86_64 it emits `call __rt_sys_` when the symbol is in the `windows_c_shim_name` registry, `call ` when it is a SysV stub- delegate, else panics — a build-time exhaustiveness guard so this class cannot silently regrow. On every other target it delegates to `bl_c`, so Linux-x86_64/macOS/aarch64 emission is byte-identical. Add ~55 SysV->MSx64 `__rt_sys_*` shims: datetime (time/localtime/gmtime/mktime/putenv->_putenv/ tzset->_tzset/getenv/gettimeofday-via-GetSystemTimeAsFileTime), math/FP (pow/sin/cos/.../fmod/round — FP args pass through xmm0/xmm1 unchanged, the shim only provides the 32-byte shadow space the bare call lacked), zlib (compress2/deflate/inflate/deflateInit2_ 8-arg reading its 2 caller-stack args before its own frame/...), pcre2 (regcomp/regexec-5arg/regfree) + libc malloc/free, net/dns via ws2_32 (getaddrinfo/inet_pton/inet_ntop/ gethostbyaddr), misc (strtoll->_strtoi64, atof, dup->_dup with cdqe, chown/lchown as no-op-success per php-src, setlocale), iconv (real shims, libiconv linked), bzip2 (BZ2_bzCompress/Init/End/BuffToBuffDecompress-6arg). Semantic-rewrite gaps (opendir/readdir/closedir/rewinddir/scandir/mkstemp, absent from msvcrt) get loud-fail stubs returning the consumer's failure sentinel, with the FindFirstFileA/GetTempFileNameA rewrite deferred. Also fix three platform values in platform/target.rs that the now-ABI-correct net shims made load-bearing: AF_INET6 (Windows=23), LC_CTYPE (Windows=2), ADDRINFOA ai_addr offset (Windows=32, matching the Win64 BSD-style layout), and the hardcoded Linux.af_inet6() in format_sockaddr's shared x86_64 path. Class 2 (~107 sites) — `abi::int_arg_reg_name` returns the MSx64 arg sequence (rcx/rdx/r8/r9) on windows-x86_64, but many sites used it to stage integer args for a hand-written SysV `__rt_*` runtime helper (reads rdi/ rsi/rdx). Relocate `runtime_helper_int_arg_reg` to abi/registers.rs (pub(crate), arch-only, extended to 6 args) and swap it in at every such site: hash/array allocation (__rt_hash_new/__rt_array_new), generators (__rt_gen_suspend/delegate), fibers (__rt_fiber_start/resume/throw/suspend/ state_eq/construct), Mixed casts (__rt_mixed_cast_*), mktime, the array- callback cluster (__rt_array_map/filter/reduce/walk/...), and SPL/exception constructors. Because the helper is arch-only, the swap is byte-identical off-Windows and only reroutes windows-x86_64. Codegen-emitted callees (the descriptor invoker, --web handler, dynamic instance-method dispatch) keep `int_arg_reg_name` — they use MSx64 on both sides. Fixing the fiber cluster unblocks part of the fiber/generator known-failures on Windows. Class 3 (14 shims) — a 32-bit Winsock/msvcrt int-status return (eax) was zero-extended into rax, so a failure (-1) read as a positive 0xFFFFFFFF and a downstream `test rax,rax; js`/`jl` missed it. Add `cdqe` after the call in the int-status shims whose consumers sign-test: connect/bind/listen/ shutdown/getsockname/getpeername (split out of the shared socket loop), setsockopt/recvfrom/sendto/dup/dup2/ioctl/lseek/pselect6. socket/accept stay untouched (they return a 64-bit SOCKET handle). Runtime-blob shim gating — the ~55 `__rt_sys_*` shims above are emitted by `emit_win32_shims` into the per-program runtime object, and the four third- party families call real library symbols (zlib compress2/..., bzip2 BZ2_*, pcre2 pcre2_reg*, iconv iconv*). Those libraries are linked only per-program (`check_result.required_libraries` + phar_archive->z,bz2 + regex->pcre2), never in the base Windows link (-lkernel32/-lmsvcrt/-lwinmm/-lws2_32/ -lbcrypt/-lshlwapi). Emitting the shims unconditionally therefore made every program that does not use those features reference symbols with no lib to resolve them -> `undefined reference` at link -> every windows-x86_64 link failed (the real wine gate, blind on the macOS/Linux CI, caught it). Gate the four families on RuntimeFeatures: pcre2 on `regex` (already computed); new `zlib`/`bzip2`/`iconv` fields (runtime_features.rs) derived in the pipeline from the same `required_libraries` signal that drives the linking, so shim emission and library linking stay consistent. The runtime object is a pure function of (heap, target, RuntimeFeatures) keyed on its assembly content hash, so gating yields distinct, correct cache objects automatically. The msvcrt/kernel32/ws2_32 shims stay unconditional (their import libs are always linked). Verified via nm: a trivial program now emits a runtime blob with zero third-party references; a gzcompress program emits only the zlib family. Restore the ENT_* HTML-escaping constant fold-value registration in prescan.rs (the import and the `for (name, value) in ENT_INT_CONSTANTS` loop), which the rebase onto main dropped while resolving the same-file conflict with the Windows path-constant additions. Without it `ENT_QUOTES + ENT_HTML5` folded to 0 instead of 51 (htmlspecialchars output was unaffected — the runtime hardcodes ENT_QUOTES escaping — but bare constant arithmetic was not). All emission on Linux-x86_64/macOS/aarch64 is byte-identical (the changes are gated on windows-x86_64 or route through arch-only helpers). Verified with zero compiler warnings, the full native codegen suite (5095/5095, 34 ignored), the win32 gating unit tests including a features-off regression guard, and the windows-x86_64 runtime blobs confirmed clean/precise via nm. Three windows-x86_64 runtime behaviors this campaign got wrong only surfaced once the shim-gating link fix let the wine gate actually run them (they were masked by the earlier undefined-reference link failure); the parity gate's allow-list flagged all three. (1) chown/chgrp/lchown/lchgrp: the no-op `__rt_sys_libc_chown`/`__rt_sys_libc_lchown` shim returned C-success (0) unconditionally, so `chown("/missing", uid)` reported true; PHP wants false on a nonexistent path. Fix: tail-jump to the existing `__rt_sys_access` (GetFileAttributesA) existence probe — it takes the path in rdi like chown does and returns 0 (exists) / -1 (missing), exactly the value the call sites `cmp eax,0; sete` on; the `jmp` preserves rsp so its `sub rsp,40` still aligns before GetFileAttributesA. (2) $argv: `__rt_sys_init_argv` used rsi as the pass-1 scan cursor, so pass 2 restarted from the consumed cursor (the trailing NUL) and stored zero argv slots, leaving `_global_argv[0]` null and crashing `__rt_build_argv`'s strlen. Fix: spill the command-line start to the frame's free 8-byte pad slot `[rsp+32]` (above the 32-byte shadow, untouched by GetProcessHeap/HeapAlloc) and reload it for the pass-2 restart. (3) stream_set_blocking(STDIN): STDIN is a console HANDLE, so the fcntl->ioctlsocket path fails with WSAENOTSOCK; the Class-3 `cdqe` (correct for real socket ioctl errors) turned the previously-accidental success into a correct-per-ABI false. PHP's stdio set_option is NOTIMPL on Windows and stream_set_blocking maps that to true, so a Windows-only helper reports best-effort success (`mov rax,1; ret`) without a syscall; the cdqe is left intact. All three are windows-x86_64-only. Verified by objdump of the cross-compiled runtime object plus win32 (56/56) and stream_set_blocking unit tests; behavior confirmed by the wine parity gate. --- .../_internal/__elephc_gmmktime_raw.md |

Windows-x86_64 keeps a loud stub, now labelled C1c (the CreateProcessA runtime lands next). Pipe-only: each descriptor must be ["pipe","r"|"w"]; any other shape makes proc_open return -1 (documented C1b limitation). The descriptor count is bounded at 8 and the descriptor_spec array may be indexed (kind 2) or hash (kind 3) — __rt_array_get_mixed_key is representation-agnostic. The child takes the mode-appropriate pipe end (write for "r", read for "w") and the parent end is pushed into the by-ref $pipes array via __rt_array_push_refcounted. proc_close reaps with wait4 and returns the raw exit code (status >> 8) & 0xff, or -1 on failure; the lowerer stamps a -1 sentinel into the resource box so the kind-5 destructor never re-reaps. Target caveats baked into the emitters: the raw macOS fork syscall returns the child pid in BOTH parent and child (disambiguated by comparing getpid before/after), SYS_close is 6 on macOS (not 3, which is read), and the Linux svc does not set flags so an explicit cmp precedes each conditional branch. Raw syscalls are emitted directly to keep the helper self-contained. The by-ref pipes ABI passes $pipes by value-pointer, so the helper must not reallocate the array; the caller pre-sizes $pipes to capacity 4 and n<=4 appends in place, which covers the pipe-only test surface. n in 5..8 is a lowerer-side follow-up. Tests: proc_open returns a resource, proc_close returns the exit status; the by-ref pipe readback test is #[ignore]d because the checker infers $pipes[n] as never (by-ref pipe writes are not yet type-tracked). The Windows PE compile-only test is retargeted to the C1c stub. --- src/codegen_support/runtime/io/proc_close.rs | 142 ++- src/codegen_support/runtime/io/proc_open.rs | 930 ++++++++++++++++++- tests/codegen/io/proc.rs | 66 +- tests/codegen/windows_pe.rs | 6 +- 4 files changed, 1074 insertions(+), 70 deletions(-) diff --git a/src/codegen_support/runtime/io/proc_close.rs b/src/codegen_support/runtime/io/proc_close.rs index 3c30c4e8e8..31ae0c7e22 100644 --- a/src/codegen_support/runtime/io/proc_close.rs +++ b/src/codegen_support/runtime/io/proc_close.rs @@ -1,39 +1,143 @@ //!

Purpose: -//! Emits the `__rt_proc_open` runtime helper. C1a ships a loud stub that reports -//! failure so the PHP surface compiles and links on every supported target; the -//! real fork/pipe/exec implementation lands in C1b (Linux/macOS) and C1c (Windows). +//! Emits the `__rt_proc_open` runtime helper, the C1b pipe-only `fork`/`pipe`/ +//! `execve` implementation for macOS-aarch64, Linux-aarch64, and Linux-x86_64. +//! Windows-x86_64 keeps a loud stub (C1c, `CreateProcessW`). //! //! Called from: -//! - `crate::codegen::runtime::emitters::emit_runtime()` via `crate::codegen::runtime::io`. +//! - `crate::codegen_support::runtime::emitters::emit_runtime()` via +//! `crate::codegen_support::runtime::io`. //! //! Key details: -//! - The stub ignores its arguments and returns -1 so the EIR boxer boxes PHP false. -//! - The C1b/C1c implementation must honor the ABI: AArch64 x0=descriptor_spec -//! array ptr, x1=command ptr, x2=command len, x3=pipes array ptr; x86_64 -//! rdi/rsi/rdx/rcx. +//! - Pipe-only: descriptors must be `["pipe","r"|"w"]`. Any other shape makes +//! `proc_open` return `-1` (documented C1b limitation; `["file",...]` and +//! friends are a follow-up). The descriptor count is bounded at 8. The +//! descriptor_spec array may be either indexed (kind 2) or hash (kind 3); +//! `__rt_array_get_mixed_key` is representation-agnostic and handles both. +//! - ABI (set by the EIR lowerer, never changed here): AArch64 `x0` = +//! descriptor_spec array ptr, `x1`/`x2` = command ptr/len, `x3` = pipes array +//! ptr; x86_64 `rdi`/`rsi`/`rdx`/`rcx`. Returns the raw child pid (`>= 0`) on +//! success or `-1` on failure; the lowerer boxes `>= 0` as `Mixed(resource, +//! kind=5)` and `< 0` as `Mixed(false)`. +//! - `$pipes` is passed by value-pointer: `lower_proc_open` loads the array +//! pointer into `x3`/`rcx` and does NOT reload it after the call. Therefore +//! this helper MUST NOT reallocate the pipes array, or the caller's `$pipes` +//! local would orphan. The caller's `$pipes = []` is pre-sized to capacity 4 +//! by `lower_array_new`'s `.max(4)` floor, which covers the C1b test surface +//! (n <= 2) and the standard 3-pipe PHP case. `__rt_array_push_refcounted` +//! only appends in place while capacity is available, so for n <= 4 the +//! caller's pointer stays valid. n in 5..8 would trigger reallocation that +//! the by-value pipes ABI cannot propagate back; that gap is a lowerer-side +//! follow-up (deferred), and the runtime avoids silent corruption by relying +//! on the caller's pre-sizing rather than calling `__rt_array_grow` here. +//! - Raw syscalls are emitted directly (not via `emitter.syscall()`/`map_syscall`) +//! so this helper stays self-contained. Linux `svc` does not set flags, so an +//! explicit `cmp x0, #0` precedes every conditional branch on AArch64 Linux. +//! - macOS fork caveat: the raw `fork` syscall (2) returns the child pid in BOTH +//! the parent and the child process (not 0 in the child). Parent/child are +//! distinguished by comparing `getpid()` before and after fork — a different +//! pid means the child. Linux's `clone` returns 0 in the child as expected. +//! - macOS close caveat: `SYS_close` is syscall 6 on macOS (NOT 3, which is +//! `SYS_read`). Using 3 would call `read()` on the pipe fd and block forever. -use crate::codegen::{emit::Emitter, platform::Arch}; +use crate::codegen_support::{abi, emit::Emitter, platform::{Arch, Platform}}; -/// Emits the `__rt_proc_open` stub: returns -1 on every target (C1a surface only). +/// Emits `__rt_proc_open`: pipe-only `proc_open` returning the child pid. /// -/// Input ABI (honored by C1b/C1c, ignored by the stub): AArch64 x0=descriptor_spec -/// array pointer, x1=command string pointer, x2=command length, x3=pipes array -/// pointer; x86_64 rdi/rsi/rdx/rcx.

Only the OS mechanism differs: CreatePipe replaces pipe2 (with an inheritable SECURITY_ATTRIBUTES; the parent end is made non-inheritable via SetHandleInformation so the child cannot deadlock on it), STARTUPINFOA.hStdInput/hStdOutput/hStdError with STARTF_USESTDHANDLES replaces dup2 (descriptor index i wires the child end into fd i for i<3; i>=3 still gets a real inheritable pipe pushed into $pipes but has no numbered-fd slot, a documented C1c limitation), and CreateProcessA replaces fork/execve. The command string is wrapped as `cmd.exe /s /c ""` in a HeapAlloc'd writable buffer (matching php-src's string-form proc_open and the C1b /bin/sh -c shell), so no argv->cmdline escaping is needed for the string surface. SetErrorMode(SEM_FAILCRITICALERRORS|SEM_NOGPFAULTERRORBOX) suppresses the modal dialogs that would hang a headless runner; any fd 0/1/2 without a descriptor is redirected to NUL; CREATE_NO_WINDOW keeps the child windowless. On success the parent closes every child end plus the unused thread handle and returns hProcess (the lowerer boxes it as a kind-5 resource); every failure path closes the handles opened so far, frees the cmdbuf, and returns -1. The three Win32 structs (SECURITY_ATTRIBUTES, STARTUPINFOA, PROCESS_INFORMATION) use standard C upward layout: field at byte offset F lives at base+F where base is the lowest stack address and the pointer passed to the API, matching the existing pselect6 fd_set convention. __rt_proc_close (emit_proc_close_win32_x86_64) reaps via WaitForSingleObject(INFINITE) + GetExitCodeProcess + CloseHandle, returning the child exit code or -1; the lowerer's -1 sentinel keeps the kind-5 destructor from re-reaping. Six Win32 imports added (CreatePipe/CreateProcessA/ WaitForSingleObject/GetExitCodeProcess/SetHandleInformation/SetErrorMode).

Every Win32 struct/out-param is laid out upward (field at base+offset); non-Windows emitters stay byte-identical. - rename(): overwrite an existing target via MoveFileExA (MOVEFILE_REPLACE_EXISTING), so php-src's write-temp-then-rename works, and translate the Win32 BOOL result to the POSIX status __rt_rename tests with `cmp eax, 0` (a successful rename previously reported failure, and a failed rename reported success). - link(): translate the CreateHardLinkA BOOL to POSIX (0/-1) so a successful hard link no longer reports failure. - disk_free_space()/disk_total_space(): __rt_sys_statfs was a stub that never called the API and left the caller's statfs buffer uninitialized; fill f_bsize/f_blocks/f_bavail from GetDiskFreeSpaceExA. - sys_get_temp_dir(): return the real Windows temp path from GetTempPathA (owned, heap-stamped string) instead of the hardcoded "/tmp". - php_uname(): fill the utsname buffer from GetComputerNameA / GetNativeSystemInfo instead of calling a nonexistent msvcrt `uname` (which self-recursed through the shim). - touch(): apply the requested atime/mtime via SetFileTime instead of ignoring the timestamps (the utimensat shim was a no-op). - fileinode(): synthesize st_ino from GetFileInformationByHandle's nFileIndexHigh:nFileIndexLow pair instead of leaving it 0. Adds GetDiskFreeSpaceExA, GetTempPathA, GetComputerNameA, GetNativeSystemInfo, GetFileInformationByHandle, GetSystemTimeAsFileTime, SetFileTime and MoveFileExA to WIN32_IMPORTS.

The boxed-Mixed fast path therefore returned value_hi instead of the stored cell pointer, and the re-box path boxed the entry from garbage. This path is only reached when __rt_array_get_mixed_key operates on hash storage (kind 3); the helper is normally used for indexed Array(Mixed) locals (kind 2), so the bug stayed latent until proc_open's descriptor_spec — an `array>` literal the checker infers as hash storage — exercised it on x86_64. proc_open then unboxed a corrupt sub-descriptor, its "pipe" tag check failed, and it returned false (=== false). AArch64 was unaffected (its reader already used x1/x2/x3), which is why the failure only appeared on the linux-x86_64 CI shard (test_proc_open_returns_resource, test_proc_close_returns_exit_status). Fix: read value_lo from rdi and value_hi from rsi (already in place for the __rt_mixed_from_value call), matching the AArch64 sibling and every other x86_64 __rt_hash_get caller. Audited all callers — this was the sole offender.

All 150 fiber/generator tests failed this way on the wine parity shards. The x86_64 register save set was not the cause: elephc's register allocator is SysV-internal on every x86_64 target (callee_int_pool = ["rbx"], callee_float_pool = []), so no value is ever live in rsi/rdi or xmm6-15 across a call and the existing SysV switch (rbx/rbp/r12-r15) is already complete. A clobbered callee-saved register would corrupt a value, not crash with empty output. Fix: on the Windows target only, __rt_fiber_switch now resyncs the NT_TIB stack bounds to whichever stack it is about to run — gs:[0x08] (StackBase) = fiber stack_top (high), gs:[0x10] (StackLimit) = fiber stack_base (low) — snapshotting and restoring the main thread's bounds via two new Windows-only globals _fiber_main_saved_stack_base / _limit. Generators share __rt_fiber_switch, so they are covered too. The register set, the 56-byte initial frame, and emit_construct_x86_64 are unchanged; non-Windows codegen is byte-identical (guard tests assert the Linux/AArch64 switch emits no gs: segment override). The Windows render assembles under x86_64-w64-mingw32-as. --- src/codegen_support/runtime/data/fixed.rs | 9 +- src/codegen_support/runtime/fibers/switch.rs | 90 +++++++++++++++++++- 2 files changed, 96 insertions(+), 3 deletions(-) diff --git a/src/codegen_support/runtime/data/fixed.rs b/src/codegen_support/runtime/data/fixed.rs index ae0b5bcbd9..3c891604f0 100644 --- a/src/codegen_support/runtime/data/fixed.rs +++ b/src/codegen_support/runtime/data/fixed.rs @@ -15,7 +15,7 @@ use super::{ RANDOM_BYTES_SOURCE_MSG, STR_REPEAT_TIMES_MSG, }; use super::super::system; -use crate::codegen_support::platform::Target; +use crate::codegen_support::platform::{Platform, Target}; use crate::types::checker::builtins::supported_builtin_function_names; /// Emit the fixed runtime `.data` section as assembly text. @@ -100,6 +100,13 @@ pub(crate) fn emit_runtime_data_fixed(heap_size: usize, target: Target) -> Strin out.push_str(".comm _fiber_main_saved_sp, 8, 3\n"); out.push_str(".comm _fiber_main_saved_exc, 8, 3\n"); out.push_str(".comm _fiber_main_saved_call_frame, 8, 3\n"); + // Windows-only: saved main-thread TEB stack bounds (NT_TIB StackBase/StackLimit), + // snapshotted when leaving the main thread and restored when a fiber switches back, + // so the fiber context switch can resync gs:[0x08]/gs:[0x10] to the running stack. + if target.platform == Platform::Windows { + out.push_str(".comm _fiber_main_saved_stack_base, 8, 3\n"); + out.push_str(".comm _fiber_main_saved_stack_limit, 8, 3\n"); + } out.push_str(".comm _rt_diag_suppression, 8, 3\n"); // elephc_web_capture: per-request output-capture mode flag read by // __rt_stdout_write.

ABI: elephc's bl_c emits a raw `call setjmp`/`call longjmp` with no SysV->MSx64 argument conversion, so the jmp_buf pointer is passed in rdi/rsi (SysV) while the MinGW entry points read it in rcx/rdx (MSx64). setjmp then writes its jmp_buf through a garbage/NULL pointer. 2. SEH: MinGW's x64 setjmp/longjmp are structured-exception-handling based -- setjmp walks the stack to capture the SEH establisher frame and longjmp unwinds via RtlUnwindEx. That walk runs off the top of elephc's small hand-rolled Fiber stacks (access violation at stack_top) and is incompatible with a stack switched to by hand. elephc's exception model does not need Windows SEH: setjmp marks a resume point and __rt_throw_current longjmps back to it after running its own frame cleanup. This adds __rt_setjmp/__rt_longjmp -- a plain callee-saved register save/restore with no SEH and no stack walking -- emitted on Windows x86_64 only, and routes bl_c("setjmp"/"longjmp") to them on that target. They take their jmp_buf SysV-style (rdi), matching every call site; the one site that staged the jmp_buf in the MSx64 arg register (the generated try/catch header) now uses the SysV-fixed runtime-helper register instead. Non-Windows codegen is byte-identical: all new code is Windows-gated and the try/catch register change resolves to the same rdi/x0 on Linux and AArch64. Validated under Wine locally -- Fiber lifecycle, suspend/resume, and uncaught-exception escape, plus basic Generators, now pass; the host AArch64 exceptions/fibers/generators suites stay 214/0. --- src/codegen/lower_inst.rs | 7 +- src/codegen_support/emit.rs | 12 +- src/codegen_support/runtime/emitters.rs | 7 + src/codegen_support/runtime/exceptions.rs | 2 + .../runtime/exceptions/setjmp.rs | 125 ++++++++++++++++++ 5 files changed, 151 insertions(+), 2 deletions(-) create mode 100644 src/codegen_support/runtime/exceptions/setjmp.rs diff --git a/src/codegen/lower_inst.rs b/src/codegen/lower_inst.rs index c7ddcf279b..6d0367a31b 100644 --- a/src/codegen/lower_inst.rs +++ b/src/codegen/lower_inst.rs @@ -2705,9 +2705,14 @@ fn lower_try_push_handler(ctx: &mut FunctionContext<'_>, inst: &Instruction) -> ); abi::emit_frame_slot_address(ctx.emitter, scratch, handler_offset); abi::emit_store_reg_to_symbol(ctx.emitter, scratch, "_exc_handler_top", 0); + // setjmp is a runtime-helper-convention call: on Windows it routes to the + // SEH-free __rt_setjmp (SysV rdi), and on Linux the C setjmp also takes its + // jmp_buf in the SysV arg-0 register, so stage the address in the SysV-fixed + // runtime-helper register (rdi/x0) on every target rather than the MSx64 arg + // register (rcx) `int_arg_reg_name` would pick on Windows. abi::emit_frame_slot_address( ctx.emitter, - abi::int_arg_reg_name(ctx.emitter.target, 0), + abi::runtime_helper_int_arg_reg(ctx.emitter, 0), handler_offset - TRY_HANDLER_JMP_BUF_OFFSET, ); ctx.emitter.bl_c("setjmp"); diff --git a/src/codegen_support/emit.rs b/src/codegen_support/emit.rs index 51810c6c90..a2677e8069 100644 --- a/src/codegen_support/emit.rs +++ b/src/codegen_support/emit.rs @@ -259,7 +259,17 @@ impl Emitter { (Platform::MacOS, Arch::AArch64) => self.instruction(&format!("bl _{}", func)), (Platform::Linux, Arch::AArch64) => self.instruction(&format!("bl {}", func)), (Platform::Linux, Arch::X86_64) => self.instruction(&format!("call {}", func)), - (Platform::Windows, Arch::X86_64) => self.instruction(&format!("call {}", func)), + (Platform::Windows, Arch::X86_64) => { + // MinGW's C-library setjmp/longjmp are SEH-based and read their + // arguments MSx64-style; elephc's SysV-staged, SEH-free replacements + // (see runtime::exceptions::setjmp) are used on this target instead. + let name = match func { + "setjmp" => "__rt_setjmp", + "longjmp" => "__rt_longjmp", + other => other, + }; + self.instruction(&format!("call {}", name)); + } (Platform::MacOS, Arch::X86_64) => { panic!("C symbol calls are not implemented yet for target macos-x86_64"); } diff --git a/src/codegen_support/runtime/emitters.rs b/src/codegen_support/runtime/emitters.rs index 91786b2d63..a63c70256e 100644 --- a/src/codegen_support/runtime/emitters.rs +++ b/src/codegen_support/runtime/emitters.rs @@ -177,6 +177,13 @@ pub(crate) fn emit_runtime(emitter: &mut Emitter, features: RuntimeFeatures) { exceptions::emit_exception_matches(emitter); exceptions::emit_throw_current(emitter); exceptions::emit_rethrow_current(emitter); + // Windows x86_64 only: emit elephc's SEH-free setjmp/longjmp.

On the windows-x86_64 target rcx != rdi, so an explicit $g->rewind() put the Generator pointer in rcx while __rt_gen_rewind read rdi (a garbage pointer) and faulted on its first field load -- a near-NULL access violation that surfaces under Wine as a Rosetta fault storm / apparent hang. foreach-driven Generator iteration was unaffected because it already staged the receiver through runtime_helper_int_arg_reg. Add remap_platform_args_to_runtime_helper_regs, which on windows-x86_64 moves each MSx64 integer argument register into the SysV register the helper reads (forward index order is collision-free for the <=4 register-passed args these small-arity helpers take), and apply it at the four generic dispatch sites that call a __rt_* helper: lower_generator_intrinsic, lower_instance_runtime_intrinsic, lower_static_runtime_intrinsic (whose hidden called-class-id occupies the first integer register), and emit_object_iterator_method_call's runtime-helper branch. Register counting goes through int_register_arg_count so a Str argument's pointer+length pair migrates as two registers rather than one. Non-Windows codegen is byte-identical: int_arg_reg_name and runtime_helper_int_arg_reg resolve to the same registers off windows-x86_64, so the remap emits nothing there. Validated under Wine: generators::send_throw 10/10 (was 0/10, all hung), generators::basic and the SplDoublyLinkedList suite 7/7 green with no regression (fibers::basic 21/21); host AArch64 generators 68/68, fibers 92/92, spl 245/245 and the new register-remap guard tests all pass. --- src/codegen/lower_inst.rs | 126 +++++++++++++++++++++++++++- src/codegen/lower_inst/iterators.rs | 4 + 2 files changed, 129 insertions(+), 1 deletion(-) diff --git a/src/codegen/lower_inst.rs b/src/codegen/lower_inst.rs index 6d0367a31b..43926700a4 100644 --- a/src/codegen/lower_inst.rs +++ b/src/codegen/lower_inst.rs @@ -9,7 +9,7 @@ //! - Results are written to fixed value-placement slots immediately after definition. //! - Unsupported opcodes fail explicitly instead of silently emitting invalid code. -use crate::codegen::platform::Arch; +use crate::codegen::platform::{Arch, Platform}; use crate::codegen::{ abi, callable_descriptor, callable_invoker_args, emit_box_current_owned_value_as_mixed, emit_box_current_value_as_mixed, emit_box_runtime_payload_as_mixed, runtime, @@ -3343,6 +3343,11 @@ fn lower_instance_runtime_intrinsic( materialize_direct_call_args_with_refs(ctx, &inst.operands, ¶m_types, &ref_params)?; let caller_stack_pad_bytes = direct_call_stack_pad_bytes(ctx, call_args.overflow_bytes); abi::emit_reserve_temporary_stack(ctx.emitter, caller_stack_pad_bytes); + let abi_param_types = abi_param_types_for_refs(¶m_types, &ref_params); + remap_platform_args_to_runtime_helper_regs( + ctx.emitter, + int_register_arg_count(&abi_param_types), + ); abi::emit_call_label( ctx.emitter, intrinsic @@ -3405,6 +3410,11 @@ fn lower_static_runtime_intrinsic( )?; let caller_stack_pad_bytes = direct_call_stack_pad_bytes(ctx, call_args.overflow_bytes); abi::emit_reserve_temporary_stack(ctx.emitter, caller_stack_pad_bytes); + let visible_abi_param_types = abi_param_types_for_refs(¶m_types, &callee_ref_params); + remap_platform_args_to_runtime_helper_regs( + ctx.emitter, + 1 + int_register_arg_count(&visible_abi_param_types), // +1 for the hidden called-class-id arg (always Int, 1 register) + ); abi::emit_call_label( ctx.emitter, intrinsic @@ -3577,6 +3587,11 @@ fn lower_generator_intrinsic( materialize_direct_call_args_with_refs(ctx, &inst.operands, ¶m_types, &ref_params)?; let caller_stack_pad_bytes = direct_call_stack_pad_bytes(ctx, call_args.overflow_bytes); abi::emit_reserve_temporary_stack(ctx.emitter, caller_stack_pad_bytes); + let abi_param_types = abi_param_types_for_refs(¶m_types, &ref_params); + remap_platform_args_to_runtime_helper_regs( + ctx.emitter, + int_register_arg_count(&abi_param_types), + ); let helper = intrinsic.runtime_helper().ok_or_else(|| { CodegenIrError::invalid_module(format!( "Generator intrinsic {:?} has no runtime helper", @@ -6014,6 +6029,54 @@ fn move_int_result_to_first_arg(ctx: &mut FunctionContext<'_>) { } } +/// Remaps the platform (MSx64) integer argument registers into the SysV +/// registers a hand-written `__rt_*` runtime helper reads, on the +/// windows-x86_64 target.

The lists had not been refreshed since early in the Windows campaign, so they still carried the whole W3-W9 ABI harvest as known-failures; this promotes every fixture that now passes on windows-x86_64 into the gated allow-list. known Windows failures : 1876 -> 1104 allow-list (gated) : 3118 -> 3998 781 formerly-known-failing tests plus 100 newly-added fixtures move into the allow-list; 0 previously allow-listed tests regressed. The promotions map onto the real fixes that landed since the list was last built: W7 setjmp/longjmp (try/catch, fibers, generators, throw-based never/enum-from/dead-code-elimination try paths), W8 builtins (touch/link/fileinode/gethostname/php_uname), and the runtime-intrinsic SysV-register fix (generator/SPL/DateTime instance and static methods). Every promotion is either green across two consecutive parity runs (608) or attributable to one of those fixes (264). IANA-explicit-timezone datetime tests, which compute wrong offsets on Windows because msvcrt has no zoneinfo database, correctly remain known-failures per the shims_time.rs contract. The files are byte-identical to a canonical regenerate: sorted test names, unchanged headers, no hand edits. --- .../support/windows_codegen_allowlist.txt | 882 +++++++++++++++++-
