digitalmars.D.learn - trouble with dmd + obj2asm under linux
- Weed (54/54) Dec 28 2008 I wrote and compile program:
- Daniel Keep (5/6) Dec 28 2008 If I had to guess, I'd say it's because you compiled without symbols.
- Weed (16/25) Dec 29 2008 Has varied nothing.
I wrote and compile program: $ dmd demo.d And I need disassembly it: $ obj2asm ./demo ./demo.d -cdemo.cod And I see asm file "demo.cod" without names of functions: ================== .init segment assume CS:.init push EBP mov EBP,ESP push EBX sub ESP,4 call near ptr LC LC: pop EBX add EBX,01056Ch mov EDX,-8[EBX] test EDX,EDX je L22 call near ptr LC0 L22: call near ptr L3F8 call near ptr LD338 pop EAX pop EBX leave ret .init ends .plt segment assume CS:.plt L0: push dword ptr [080591A4h] jmp dword ptr [080591A8h] ================== From other person I have received such listing with names: ================== assume CS:_D4test1C5opAddMFC4test1CZC4test1C L0: push EAX push EBX push offset FLAT:_D4test1C7__ClassZ call near ptr __d_newclass mov EBX,EAX mov EAX,8[ESP] mov ECX,8[EAX] mov EDX,010h[ESP] ================== What it is necessary to make such listing? $ obj2asm Digital Mars .OBJ file disassembler Version 8.51.3 Copyright (C) Digital Mars 2000-2007.
