Hi I want to check some .efi and call format stuff. However I don't know exactly how to produce assembly output from edk2 gcc. I was trying to tweak .dsc. The problem is that the last file is compile overwrites the rrest for every module. I pasted this at the end of MdeModulePkg last line -Wa,-adhln=asmdump.asm
However asmdump.asm only contains listing for the last file compiled in the module Is there a better way to do this?

The way I generally do this (for OVMF) is as follows:
- run a complete NOOPT build
- run a command like:
objdump -S Build/Ovmf3264/NOOPT_GCC48/X64/MdeModulePkg/Core/PiSmmCore/PiSmmCore/DEBUG/PiSmmCore.debug \ | less
This is going to give you a disassembly intermixed with C source code, for the "MdeModulePkg/Core/PiSmmCore/PiSmmCore.c" file.
