Umm... yes, it can. It's in the dmd.zip file. Mike Swieton __ Freedom is the right to make the wrong decision.

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. :) -eye

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 <g>.

You're not kidding, my funky brother!

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