Jit Code Disassembler? #121
Description
motivation
disassemble the code into x86/aarch64 instruction format for debug usage, this can be gated behind a disassemble feature
example
demo code
// in JitMemory //capstone = { version = "0.13", optional = true } let cs = capstone::Capstone::new() .x86() // shall handle x86 and aarch64 in the real world .mode(arch::x86::ArchMode::Mode64) .syntax(arch::x86::ArchSyntax::Att) .detail(detail) .build() .unwrap() let code = &self.contents[0..self.offset]; let insns = cs.disasm_all(code, 0).unwrap(); for insn in insns { println!("{}", insn); }output
for instructions
let prog = &[ 0x71, 0x10, 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, // ldxh r0, [r1+2] 0x95, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, // exit ];output is
