Subject: OSX 32-bit assembler warnings.
I made some 32-bit builds on OSX just to test the legacy MMX/SSE builds out (and some bugs were indeed found and fixed).
Due to my habit of always supplying -s to make, I saw these warnings:
md4-mmx.S:280:Alignment too large: 15. assumed.
md4-mmx.S:314:Alignment too large: 15. assumed.
md5-mmx.S:48:Alignment too large: 15. assumed.
That made me laugh, just like the guy in the first google hit:

Do I understand right that it will it align to 32K? That's a lot but I presume it will work fine. And the build does work fine.
If we said .balign instead, would some other assemblers not understand it? Or perhaps we could/should use some #ifdef stuff? I see now there is some DO_ALIGN stuff in x86.S but I can't say I understand it. Does it depend on defines in arch.h? OSX does not have it's own.
