Hi,
Does anyone know how to convert D to x86 assembly? I noticed obj2asm in the bin
folder, but I don't know how to use it. Cygwin and DOS both won't run it.

thanks in advance, Jerry

obj2asm is available as a part of the Digital Mars Extended Utility Package (http://www.digitalmars.com/eup.html).  I think the file in dmd/bin is probably a reference file of some sort.  For $15, the EUP is a great deal IMO.

Why is it free with the Linux distro, but you have to guy the EUP to get it on Windows?

No idea.  (and I suppose that's what dmd/bin/obj2asm is, huh)

But wait. Does obj2asm produce the intel syntax or GAS(AT&T) syntax (on Windows
and Linux)?

Intel syntax only.

\dmd\bin\obj2asm is the linux version of obj2asm. obj2asm.exe is the Windows version, and it comes with the Extended Utility Package for $15.

So why is it free only on linux? Because the only ones using it will be DMD users. On Windows, obj2asm.exe is incredibly useful (it'll read OMF 16 and 32 bit, MS-COFF, and ELF), and very often it is the only tool people want from Digital Mars.

As a side-note, if you want to convert D to assembly with GDC you use:

	gdc -S file.d

If you run that on "file.d", it will create "file.s" with (GNU) asm...

--anders

PS. You can of course also add other flags too, like -O2 and -frelease

From the docs here: http://www.digitalmars.com/ctg/obj2asm.html

"OBJ2ASM disassembles object (.obj) files in Intel OMF, Microsoft COFF format,
or linux ELF format. (DMC++ generates Intel OMF format object files.)"
