[M3devel] atomic problem

[Jay K]

I don't like such "non-determinism".

  Granted, it isn't really non-deterministic.

I want to know which other machines things will run on, not

just have them run on the machine on which they are built.

Building things yourself is nice, but not doing it is also nice too.

 And not doing it on every machine even if you do build it yourself

   is nice.

 

 

Which "reminds", or rather "convinces" me..we should just

never do native builds in m3cc and m3gdb.

We should pass imho what we believe to be the

platform, but with carefully chosing which processor.

Gotta test like every platform though.

I think -march=native works too assuming you are on a modern x86.

It looks like i586 suffices. I checked that in to the LINUXLIBC6 config file.
Probably I386_DARWIN, FreeBSD4, NetBSD2_i386 etc. need updating.
We can probably adjust m3cc/m3makefile.
The platforms.quake file won't do, since native builds don't use it.

Probably an out of date m3cg.
I'll see.

Could be I'm out of date or building in the wrong order.
I'll maybe dig into it.
