*	DAGCombiner: Make the post-legalize vector op optimization more aggressive.	Benjamin Kramer	2013-02-21
\| \| \| \| \| \| \| \|	A legal BUILD_VECTOR goes in and gets constant folded into another legal BUILD_VECTOR so we don't lose any legality here. The problematic PPC optimization that made this check necessary was fixed recently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175759 91177308-0d34-0410-b5e6-96231b3b80d8
*	Teach DAG combine to handle vector logical operations with vectors of all 1s ↵	Craig Topper	2012-12-08
\| \| \| \| \| \|	or all 0s. These cases can show up when vectors are split for legalizing. Fix some tests that were dependent on these cases not being combined. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169684 91177308-0d34-0410-b5e6-96231b3b80d8

\| \| \| \| \| \|	instructions only look at the highest bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147426 91177308-0d34-0410-b5e6-96231b3b80d8
*	Kill and collapse outstanding DomainValues.	Jakob Stoklund Olesen	2011-11-07
\| \| \| \| \| \| \| \| \| \| \| \|	DomainValues that are only used by "don't care" instructions are now collapsed to the first possible execution domain after all basic blocks have been processed. This typically means the PS domain on x86. For example, the vsel_i64 and vsel_double functions in sse2-blend.ll are completely collapsed to the PS domain instead of containing a mix of execution domains created by isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144037 91177308-0d34-0410-b5e6-96231b3b80d8
*	Expand V_SET0 to xorps by default.	Jakob Stoklund Olesen	2011-11-07
\| \| \| \| \| \| \| \| \|	The xorps instruction is smaller than pxor, so prefer that encoding. The ExecutionDepsFix pass will switch the encoding to pxor and xorpd when appropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143996 91177308-0d34-0410-b5e6-96231b3b80d8
*	Improve code generation for vselect on SSE2:	Nadav Rotem	2011-10-19
\| \| \| \| \| \| \| \| \| \| \|	When checking the availability of instructions using the TLI, a 'promoted' instruction IS available. It means that the value is bitcasted to another type for which there is an operation. The correct check for the availablity of an instruction is to check if it should be expanded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142542 91177308-0d34-0410-b5e6-96231b3b80d8
