COFF support for Win32 merged
I though that this might be important enough to share on the announce list: A pull request [1] by Rainer Schuetze which adds COFF support for Win32 has recently been merged by Walter. It seems to be enabled using the -m32mscoff flag. [1] https://github.com/D-Programming-Language/dmd/pull/3843 -- /Jacob Carlborg

I have just recompiled dmd, but I don't see that new compiler switch (dmd 2.067). I am compiling in a wrong way? Bye, bearophile

are you sure that you have latest git then? yes, i know that this is
very silly question, but sometimes... ;-)
unfortunately, i have no windows boxes (neither cross-compilers), so
can't check it myself. but i see this in mars.c:
#if TARGET_WINDOS
else if (strcmp(p + 1, m32mscoff) == 0)
{
global.params.is64bit = 0;
global.params.mscoff = true;
}
#endif
...
static const char* parse_arch(size_t argc, const char** argv, const
char* arch) {
for (size_t i = 0; i argc; ++i)
{ const char* p = argv[i];
if (p[0] == '-')
{
if (strcmp(p + 1, m32) == 0 || strcmp(p + 1, m32mscoff)
== 0 || strcmp(p + 1, m64) == 0) arch = p + 2;
else if (strcmp(p + 1, run) == 0)
break;
}
}
return arch;
}
so i believe that it should work.

You will need to use his unmerged branches of druntime and phobos also: https://github.com/rainers/druntime/tree/coff32 https://github.com/rainers/phobos/tree/coff32 Hopefully those get merged next, as I think this could be a big feature for the 2.067 release. Nice work, Rainer.

Andrei Alexandrescu: schwartzSort comes to mind -- Andrei forgot the smiley :o) -- Andrei Yeah that's an infamous example. Standard libraries should avoid too much hard to write identifiers. Bye, bearophile

[1] https://github.com/D-Programming-Language/dmd/pull/3843 Yes, it did turn out to be a much less intrusive change than I anticipated, and Rainer's work also included some sensible refactoring which was valuable in and of itself.

This enables using the MS C runtime for Win32 programs, but you could already use VS for debugging thanks to cv2pdb (also written by Rainer!). Though, now that the debug information is not channeled through the CodeView format, it might be more accurate. Also, what's the deal on Win64? -- Andrei Win64 is COFF-only because OPTLINK is 32-bit-only, so PDB was DMD's only Win64 debugging format (not that that's a bad thing).
