Dear GCC Community, I hope this message finds you well. I am currently working on a Debian-based system running Ubuntu 22.04 and using GCC version 11.4.0. I have compiled a C source file using GCC with the -O2 optimization flag, resulting in an optimized binary. I am now interested in generating high-level C code from this optimized binary for analysis and understanding. Could you kindly advise me on which decompiler would be most suitable for this purpose? Specifically, I would appreciate recommendations for decompilers that perform effectively on GCC-based optimized code.
This can be done with `objdump`:
objdump FILE --disassemble # disassemble all code
objdump FILE --disassemble=foo # disassemble `foo`; may be specified
# multiple times
There are some useful options:
-r Print relocations, so they don't appear to be mysterious zeroes.
-w Do not truncate line length to 80 cols.
-Mintel USe Intel syntax for x86.

Best regards,
LIU Hao
