…ly (#213481) apply #209900 (comment) fix the duplication that causes issues like this: ``` lit-23: /__w/llvm-project/llvm-project/compiler-rt/test/builtins/Unit/lit.cfg.py:186: fatal: builtins_source_features contains duplicates: ['librt_has_floatdidf', 'librt_has_floatdisf', 'librt_has_floatundidf', 'librt_has_floatundisf'] FAILED: compiler-rt/test/builtins/CMakeFiles/check-builtins /__w/llvm-project/llvm-project/build/compiler-rt/test/builtins/CMakeFiles/check-builtins cd /__w/llvm-project/llvm-project/build/compiler-rt/test/builtins && /usr/bin/python3 /usr/bin/lit-23 -sv --show-xfail --show-unsupported /__w/llvm-project/llvm-project/build/compiler-rt/test/builtins/TestCases /__w/llvm-project/llvm-project/build/compiler-rt/test/builtins/Unit/X86_64LinuxConfig ninja: build stopped: subcommand failed. ``` Part of #197824
Previously, we used `SymbolUserMap::replaceAllUsesWith` to replace symbols, but this could not update the symbol table cached by `SymbolUserMap` during traversal, leading to a crash. This PR switches to `SymbolTable::replaceAllSymbolUses`, which always operates on the latest symbol table and avoids the crash. Fixes #209648.
…213431) Add support for version 0.19 of the Smijt, Ssijt, Smehv, and Ssehv extensions from the RISC-V fast interrupt specification.
…212040) Related to #185382 CIR lowering for store intrinsics (`vst[234]_*`/`vst[234]q_*`) (https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#store) Port tests: - `clang/test/CodeGen/AArch64/neon-intrinsics.c` - `clang/test/CodeGen/AArch64/neon-ldst-one.c` - `clang/test/CodeGen/AArch64/poly64.c` to `clang/test/CodeGen/AArch64/neon/store.c`
…214072) Summary: This uses the `llvm-gpu-loader` tool to invoke OpenCL test kernels. This routes OpenCL through the standard compute runtimes, which aren't exactly 1-to-1 with OpenCL, but it's close enough. Obviously, the best solution would be to have a real OpenCL host library that can launch these, but this is the best we can get in-tree and is very sipmle, write kernel, test kernel. The goal is to have a lot more tests run here, but this just gets the basic infrastructure in place. We won't be able to do full conformance like external suites, like exhaustive math, but I think its' a step in the right direction. It looks like this on my side: ```console $ ninja check-libclc-amdgpu-amd-amdhsa-llvm ``` This requires building with the LLVM `offload/` runtime enabled for the source compiler.
Implement the GCC/Clang dependency-file flags for flang, which it previously rejected as unknown arguments: -M, -MM, -MD, -MMD, -MF, -MT and -MQ. Feature: - -MD/-MMD : write a .d file alongside a normal compile - -M/-MM : run through semantics; emit deps to stdout by default - -MF : dependency-file path - -MT/-MQ : target name (verbatim / Make-quoted) (-M==-MM and -MD==-MMD; Fortran has no system/user header split.) Design: - `-M`/`-MM`: driver passes `-fsyntax-only -dependency-file - -MT <target>` to `-fc1`. Running through semantics resolves USE statements so module file dependencies are captured in the output. This deviates from clang's prescan-only behaviour for -M, but is intentional: unlike C/C++ #include, Fortran's USE statement is resolved at the semantic stage, not during preprocessing. - `-MD`/`-MMD`: driver passes `-dependency-file foo.d -MT <target>` alongside the normal compile action. The object file is produced as usual, and the dependency file is written as a side effect. - `-MF <path>` overrides where the dependency file is written. `-MT <target>` sets the target name (the part before the colon in the Make rule) verbatim. `-MQ` does the same but additionally quotes characters that are special to Make. - In `-fc1`, `-dependency-file` and `-MT` are stored in the frontend options. After the action, `writeDependencyFile()` is called unconditionally. It collects every file opened during the action — the source plus all INCLUDE/#include/USE module files — via `GetIncludedFilePaths()`, then writes the `target: source includes...` Make rule to the specified file, or stdout if the path is `-`.
Fix imaginary value in Scalar and Complex subtraction Issue #213998
…sions (#199622) Add a statement attribute that suppresses MakeAvailable/MakeVisible cache operations on AMDGPU atomic instructions while preserving memory ordering (waits). The attribute takes a string argument specifying the mode. Currently "none" is the only supported mode. The resulting atomic or fence instruction carries !mmra !{!"amdgcn-av", !"none"} metadata. This only works with builtins that get lowered to intrinsics or instructions. The attribute does not survive inlining. For example, a C++ std atomic is typically a wrapper around a Clang builtin, and applying this attribute on the std atomic does not remove the MakeAvailableMakeVisible semantics built into it.

Define `__SIG_ATOMIC_TYPE__` for compatibility with GCC. This fixes `riscv32-netbsd` and `riscv64-netbsd` system headers that define `sig_atomic_t` using this macro. Reference: https://gcc.gnu.org/onlinedocs/gcc-16.1.0/cpp/Common-Predefined-Macros.html Follow up of #199678, Closes #213895
