Eli Friedman 526e6d045f Don't try to custom-lower 64-bit add-with-overflow and friends on x86-32; the 
x86 backend currently doesn't know how to handle them.

This doesn't really fix anything because LegalizeTypes doesn't know how to
handle them either.  We do get a better error message, though.

Devang Patel 89f2db6b67 DwarfWrite is now smart enough to drop debug value pointing to undefined register. Update this test to avoid this. 
iSel not properly lowring argument into a well formed DBG_VALUE in some cases is a separate issue and not related to the test in this testcase.

Jakob Stoklund Olesen 7b0ac865a4 Properly compose subregister indices when coalescing.

Chris Lattner 14c46517b5 fix PR6623: when optimizing for size, don't inline memcpy/memsets

llvm-svn: 105064
 2010-05-28 23:48:31 +00:00
Jakob Stoklund Olesen e02996ca8f Merge the SystemZ subreg_even32 SubRegIndex into subreg_32bit. The SubRegIndices 
were overspecified when inheriting sub-subregisters, for instance:

R0Q:subreg_even32 = R0Q:subreg_32bit = R0Q:subreg_even:subreg_32bit.

This meant that composeSubRegIndices(subreg_even, subreg_32bit) was ambiguous.
