Umm... yes, it can. It's in the dmd.zip file.

Obj2asm is an extremely useful tool, it's only $15 at
www.digitalmars.com/eup.html, comes with a bunch of other very useful tools,
and helps keep the monitors glowing at Digital Mars.

too. I was wondering if D compiler will be able to produce assembly listing
itself (as do most (if not all) C++ compilers). This feature will greatly help
isolating bugs in code generation and should not hit your obj2asm sales much <g>

Portable C and C++ compilers like GCC and LCC usually handle assembly as 
text as their intermediate form, and then pass it to an assembler, which 
can be either embedded or even external. DigitalMars compilers are 
different in this respect, that they generate machine code directly 
without going through assembly. Well, it's no surprise their backends 
aren't "portable" either. Making the compiler output assembly would 
essentially mean embedding a disassembler. It doesn't seem Walter would 
intend to do it, since else he probably would have done it years ago. :)

That makes sense, thanks for explanation. Will have to use some 3rd party
disassembler then.
BTW, are there any benefits in DM approach? Slightly faster compilation time, or
something else?

If you compare DMC compile speed with gcc, I think that'll be clear enough

the ../dmd/bin directory. Unless of course you are using a W$ OS, in 
which case there is none for M$.
