Andrea Di Biagio e9c0b5aba6 [DAGCombiner] Teach how to fold sext/aext/zext of constant build vectors. ... This patch teaches the DAGCombiner how to fold a sext/aext/zext dag node when the operand in input is a build vector of constants (or UNDEFs). The inability to fold a sext/zext of a constant build_vector was the root cause of some pcg bugs affecting vselect expansion on x86-64 with AVX support. Before this change, the DAGCombiner only knew how to fold a sext/zext/aext of a ConstantSDNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200234 91177308-0d34-0410-b5e6-96231b3b80d8		2014-01-27 18:45:30 +00:00
