Compile RISCV binary and run on BOOM

The tool and instruction is borrow from the official riscv-tests repo.

Precondition: Step up riscv toolchain

Follow the chipyard setup guide in another repo.

Generate testcase

cd case_generation
python3 test_case_generation.py
cd ../isa/rv64ui
make

Steps:

1. Use simple.S as a skeleton. Thw testcode can be write at the section between RVTEST_CODE_BEGIN and RVTEST_PASS.

RVTEST_CODE_BEGIN
# Place to insert custom test code. 
RVTEST_PASS

2. Use the following riscv gcc commad to compile program

riscv64-unknown-elf-gcc -march=rv64g -mabi=lp64 -static -mcmodel=medany -fvisibility=hidden -nostdlib -nostartfiles -T link.ld -o simple simple.S

We get binary simple.

3. We can use riscv binary dump to inspect the binary

riscv64-unknown-elf-objdump --disassemble-all --disassemble-zeroes --section=.text --section=.text.startup --section=.text.init --section=.data simple
