Quentin Colombet	e2e0548d77	[R600] Replicate old DAGCombiner behavior in target specific DAG combine. ... build_vector is lowered to REG_SEQUENCE, which is something the register allocator does a good job at optimizing. llvm-svn: 187397	2013-07-30 00:27:16 +00:00
Quentin Colombet	6bf4baa408	[DAGCombiner] insert_vector_elt: Avoid building a vector twice. ... This patch prevents the following combine when the input vector is used more than once. insert_vector_elt (build_vector elt0, ..., eltN), NewEltIdx, idx => build_vector elt0, ..., NewEltIdx, ..., eltN The reasons are: - Building a vector may be expensive, so try to reuse the existing part of a vector instead of creating a new one (think big vectors). - elt0 to eltN now have two users instead of one. This may prevent some other optimizations. llvm-svn: 187396	2013-07-30 00:24:09 +00:00
