rv8-bench
2+
===============
3+
4+
The rv8 benchmark suite contains a small set of currently integer
5+
centric benchmarks for regression testing of the rv8 binary
6+
translation engine. The suite contains the following test programs:
7+
8+
- qsort
9+
- aes
10+
- norx
11+
- dhrystone
12+
- primes
13+
- miniz
14+
- sha512
15+
16+
## Dependencies
17+
18+
rv8-bench depends on the following software:
19+
20+
- [rv8](https://github.com/rv8-io/rv8/)
21+
- [riscv-qemu](https://github.com/riscv/riscv-qemu/)
22+
- [musl-riscv-toolchain-7.1.0-2](https://github.com/rv8-io/musl-riscv-toolchain/releases/tag/v7.1.0-2)
23+
- [Node.js](https://nodejs.org/)
24+
25+
_Installing Node.js on macOS with brew_
26+
```
27+
brew install node
28+
```
29+
30+
_Installing Node.js on Debian Stretch_
31+
```
32+
sudo apt-get install nodejs
33+
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
34+
```
35+
36+
_Installing musl-riscv-toolchain_
37+
```
38+
git clone https://github.com/rv8-io/musl-riscv-toolchain.git
39+
cd musl-riscv-toolchain
40+
for i in riscv32 riscv64 i386 x86_64 arm aarch64; do sh bootstrap.sh $i ; done
41+
```
42+
43+
_Installing rv8_
44+
```
45+
git clone https://github.com/rv8-io/rv8.git
46+
cd rv8
47+
git submodule update --init
48+
make -j4 && sudo make install
49+
```
50+
51+
_Installing riscv-qemu_
52+
```
53+
git clone https://github.com/riscv/riscv-qemu.git
54+
cd riscv-qemu
55+
git submodule update --init
56+
./configure --target-list=riscv64-softmmu,riscv32-softmmu
57+
make -j4 && sudo make install
58+
```
59+
60+
## Building
61+
62+
To build the rv8 benchmarks for riscv32, riscv64, i386 and
63+
x86_64 run `make` in the rv8-bench directory:
64+
65+
```
66+
cd rv8-bench
67+
make
68+
```
69+
70+
## Running
71+
72+
To see how to run the benchmarks execute `npm start` for usage instructions:
73+
74+
```
75+
npm start bench <benchmark> <target> <opt> <runs>
76+
npm start gather
77+
```
