digitalmars.D.learn - trouble with dmd + obj2asm under linux

reply Weed <resume755 mail.ru> writes:
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?

If I had to guess, I'd say it's because you compiled without symbols. Try this: $ dmd -g demo.d -- Daniel

Has varied nothing. Names of functions and were earlier in a binary file, they are enumerated from above (I have reduced them): public _D2rt8typeinfo7ti_uint10TypeInfo_k5tsizeMFZk public _d_isbaseof2 public _D6object14TypeInfo_Const5flagsMFZk extrn pthread_key_create GLIBC_2.0 public _D4core6thread5Fiber9freeStackMFZv public _D6object14TypeInfo_Tuple7getHashMFxPvZk public _D2rt4deh29FuncTable6__initZ .init segment assume CS:.init push EBP mov EBP,ESP However, objdump works quite normally for D a code
