[M3devel] new target names -- SOLsun vs. SOLgnu? I386_SOLARIS Sun cc vs. GNU cc?

[Jay K]

I thought I had sent a followup on this:
 https://mail.elegosoft.com/pipermail/m3devel/2010-April/006836.html


Can you suggest precise platform name and precise other decisions?


This is coming up sooner-not-later also for I386_SOLARIS/AMD64_SOLARIS.
The provided machine's readme says we have Solaris 8, 9, 10 machines,
with multiple versions of Sun and GNU compilers.


Do I just declare that we only support Sun compiler?
Anyone who for some reason wants GNU gets to "rewrite" the config file and keep it to himself?
Or we somehow provide Sun and GNU "configurations" and user can pick one?


Do we have I386_SOLARIS_SUNCC and I386_SOLARIS_GNUCC?
or I386_SOLARIS_CC and I386_SOLARIS_GCC?

or I386_SOLARIS_SUN and I386_SOLARIS_GNU?




I wouldn't mind "helping" people and author the gcc support in quake.
  With some plan to move quake into cm3 in future.
But I don't want this to snowball into having to list extra identical platforms everywhere,
as has been the case for SOLsun and SOLgnu.
  Granted, platform-specific code is extremely rare now.


But the "one target, multiple configurations" of NT386/GNU/MINGNU did seem to get too messy/confusing.

Sounds reasonable.

SPARC32_SOLARIS_SUN vs. SPARC32_SOLARIS_GNU? SPARC_SOLARIS_SUNCC, SPARC_SOLARIS_GCC?
"target is underscore separated list of relevant names, usually two but not limited to two"?
 
 
Drop SOLgnu and just equate SPARC32_SOLARIS with SOLsun?
Given that the reason for SOLgnu was because cc was not bundled with OS at some point?
  But now gcc and cc are both bundled as I understand!
 
 
Do some sort of autoconfig, sensitive to the CC environment variable?
 That's actually pretty easy and pretty cheap. Not a terrible idea.
 
 
I'm not really pushing hard on this topic, just that I want to cross build Cygwin from non-NT and was hitting minor problems.
Mainly I want to see if Cygwin pthreads works now, now that the hanging test case got "rewritten", so I can drop the SchedulerPosix.m3 file which duplicates content verbatim out of ThreadPThread.m3..
