digitalmars.D.learn - Code Listing?

Hello

I'm just experimenting (playing) with the D language, and i wonder if
there is a compile option that enables code listing??

Thanks

Not sure what you mean, but if you turn on -cov (for coverage), you should
be able to get a listing showing how many times a given statement is
executed.

Lars,

I mean generated assembly coed listing.

gdc -S, or use "obj2asm" with DMD objects.

I thought there would be a feature that enables listing parts of the
code, not the whole obj file (a pragma for example that I can apply
to a block of code)..

Why there is no such feature?

Because DMD doesn't compile to assembly which is then assembled by another 
assembler?

Jarrett,

C++ for example can generated asm code listing. It's useful in
debugging, code optimization, and for me, it's interesting in
learning the language by seeing how the compiler generates the code.

There is nothing that prevents D from having such feature, as it
generates directly executable code and does not rely on a VM.

anders,

obj2asm coming with DMD is a Linux executable? What about a windows
equivalent?

Then ask for Walter to add it to DMD.  There's no reason why it doesn't have 
it other than he didn't think about it, or he didn't think it necessary.

Man, it would be nice.  But the Windows version of obj2asm is available from 
Digital Mars as well -- in the $15 extended utilities package.  I'm not 
entirely sure why Walter distributes the Linux version for free.

As far as disassembling the individual object files, you'd probably have 
luck using Borland tools to do so, as DMD uses the OMF object format.  But 
for fully compiled EXEs or DLLs, you can try the Microsoft DUMPOBJ utility, 
if you can get your hands on it.  It works well.

Failing all of that, you can use a debugger to step through your program and 
look at the assembly listing on the fly.  It's not all at once, but hey.

The Open Watcom compiler tools work with DMD.
Also DDL is becoming a good alternative to DUMPOBJ.
