Hi,

RW> You can get MSVC to output a .asm file with the /FA option -

Too bad you can't use that output as input to ML
(Microsoft Macro Assembler) to produce an .obj/.exe file
(unless you're ready to give up exception handling support ^^ Oh no !
The horrors !).

For example, you might want to try to compile the following very
simple code:

  void f ();
  int main ()
  {
    try { f (); } catch (...) { return 1; }
    return 0;
  }

using

  CL /c /EHa /FAs Main.cpp
  ("Compile only, don't link, enable exceptions, generate ASM")
  
and then try to process the output with

  ML /c Main.asm
  ("Assemble only, don't link")

You will get a rightful complaint from the Assembler, due to invalid
nesting of the SEGMENT/ENDS/PROC/ENDP directives:

...
_TEXT   SEGMENT           ; Begin segment.
...
_main   PROC NEAR         ; Begin procedure.
...
_TEXT   ENDS              ; End segment (Missing ENDP before this).
text$x  SEGMENT           ; Begin another segment (exc. handling code).
...
text$x  ENDS              ; End segment.
_main   ENDP              ; End procedure (badly nested).
...

I've uploaded the full example here: http://tinyurl.com/5by89y (2 KB).
I guess one needs to create a custom tool to process the ASM file.

(The Borland/CodeGear toolchain does not have this problem, though.)
