Compilers and ELF. #2

Open XC1a opened 2 years ago

XC1a commented 2 years ago

I use the LLVM to generate the ELF of RISCV64. But I run the CFG gen, there is nothing happened and I found the "executable.funcs" is empty. If there are some compiler requires of riscv-cfg. Can I use the LLVM?

Hi. Debug info is required to fill executable.funcs. Compile with -g option.

It works, thanks! I have another question, this work can analyze taget address of indirect jump instructions in some situation, like jarl. For example, analyze the register value before the jump instruction. Thanks so much!
