Yeah, that's the message... what I wonder is this is to be expected.
Does SSE steal or add registers?
-march=pentium-mmx -m3dnow
seems to work, though. Is it just a coincidence that gcc optimizattion
uses some registers with high march (and SSE) that it didn't use with lower march?
I'm wondering if it's the code that is just lucky to compile with some
march settings and not so lucky with others or if it's a gcc bug or
whatever...
Thomas.
