Context menu "Convert to __usercall golang (Shift-G)"
⚠️ Probably obsolete since IDA 7.6 properly support golang binaries analysis. But may be helpful in cases when IDA doesnt recognize golang binaries.⚠️ This feature is (temporary?) turned off since IDA 9.0 (too many things need to rewrite to new IDA API)
This feature has been added for anayizing binaries produced by Go compiler. Press "Shift-G" on the first line of pseudocode and:
- Calling convention of the function will be changed to
__usercall - All registers will be marked as spoiled
- Return type will be set to "
void" - The function arguments will be destroyed and recreated from the stack frame
- Stack arguments area will be marked as deprecated for "global dead elimination" decompiler step
- Local variables that share the same stack location will be mapped together
📝 Note:
- Even after all these steps Golang decompiled pseudocode is in a mess because of hard stack locations re-usage.
- Do not forget to switch compiler (menu Options/Compiler) to "GNU C++"
