Andrea Di Biagio 6c347524e2 [X86][AVX] Fix failure due to a missing ISel pattern to select VBROADCAST nodes (PR23259). ... This fixes a regression introduced at revision 218263. On AVX, if we optimize for size, a splat build_vector of a load is lowered into a VBROADCAST node. This is done even if the value type of the splat build_vector node is v2i64. Since AVX doesn't support v2f64/v2i64 broadcasts, revision 218263 added two extra tablegen patterns to allow selecting a VMOVDDUPrm from an X86VBroadcast where the scalar element comes from a loadi64/loadf64. However, revision 218263 forgot to add an extra fallback pattern for the case where we have a X86VBroadcast of a loadi64 with multiple uses. This patch adds the missing tablegen pattern in X86InstrSSE.td. This patch also adds an extra test to 'splat-for-size.ll' to verify that ISel doesn't crash with a 'fatal error in the backend' due to a missing AVX pattern to select v2i64 X86ISD::BROADCAST nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235509 91177308-0d34-0410-b5e6-96231b3b80d8		2015-04-22 14:53:39 +00:00
