Simple script for testing RISC-V codegeneration of RISC-V extensions (currently bitmanip only)
git clone https://github.com/SpinSpinSugar/riscv-checkSetup venv:
python3 -m venv .env
source .env/bin/activate
pip install -r requirements.txtExample (gcc):
python3 riscv_check.py riscv64-unknown-linux-gnu-gcc rv64gv_zba_zbb_zbc_zbs lp64d 3
python3 riscv_check.py --format="csv" riscv64-unknown-linux-gnu-gcc rv64gv_zba_zbb_zbc_zbs lp64d 3Example (clang):
python3 riscv_check.py --params="--target=riscv64" clang rv64gv_zba_zbb_zbc_zbs lp64d 3
python3 riscv_check.py --params="--target=riscv64" --format=csv clang rv64gv_zba_zbb_zbc_zbs lp64d 3 cd tests
# for example zba
mkdir %YOUR RISC-V EXTENSION NAME%
cd %YOUR RISC-V EXTENSION NAME%
# for example andn
mkdir %INSTRUCTION_NAME%
# for example andn64.c
touch %TEST_NAME%.cFile format (function name is important!!!):
#include <stdint.h>
int64_t test(args...) {
//your code that you expect compiler to convert to INSTRUCTION_NAME assembly line
