7c3a8d0056 Really. Why doesn't every arch support MMX?

bb645b395c Same isPhysRegAvailable bug as local register allocator. 
llvm-svn: 47500
 2008-02-22 20:31:32 +00:00
Evan Cheng
b8e7eb2b1b Really really bad local register allocator bug. On X86, it was never using ESI, EDI, and EBP because of a bug in RALocal::isPhysRegAvailable(). For example, when 
it checks if ESI is available, it then looks at registers aliases to ESI. SIL is marked -2 (not allocatable) but isPhysRegAvailable() incorrectly assumes it is in use and returns false for ESI.

a64d4179d4 copy mmx values from/to memory with GPRs on x86-32 
instead of with mmx registers.  This horribleness is apparently
done by gcc to avoid having to insert emms in places that really 
should have it.  This is the second half of rdar://5741668.

e70bc39d74 Start using GPR's to copy around mmx value instead of mmx regs. 
GCC apparently does this, and code depends on not having to do
emms when this happens.  This is x86-64 only so far, second half
should handle x86-32.

just one or more.

b3c8d120dc Make the clobber analysis a bit more smart: we only are careful about 
early clobbers if the clobber list contains a *register* not some thing
like {memory}, {dirflag} etc.

4f87f1c087 Treat clobber operands like early clobbers: if we have 
any, we force sdisel to do all regalloc for an asm.  This
leads to gross but correct codegen.

This fixes the rest of PR2078.
