digitalmars.D.learn - How do I view assembly?

Hi,

Is there a way by which I can see the assembly code generated by 
the D compiler similar to the -S etc switches on GCC?

Regards,
Sandeep Datta.

Not with DMD. What you have to do is disassemble the file with objdump 
-D foo.o (add -M intel to maintain your sanity)

On Windows, there's a dump tool called dumpobj shipped with DMD IIRC.

I think you refer to "obj2asm", that's not shipped with DMD.

(A -S (or -asm) switch for DMD would be quite nice and useful).

Hmm, I could've sworn there was a tool for this shipped with the DMD 
tool chain... odd.

The trouble is that DMD assembles code in memory rather than deferring 
to an assembler...

The Linux folder of dmd has obj2asm, but the Windows version
is part of Walter's $15 extended utilities package.

Well, there's always $INSERT_RANDOM_FREE_DISASSEMBLER then, I guess.
