[X86] Make memcmp vector lowering handle arbitrary expansions

2019-10-30T07:12:57+00:00

Teach combineVectorSizedSetCCEquality() to handle arbitrary memcmp expansions but do not change any default policy for now. This also fixes a bug in the memcmp expansion itself when large displacements are needed. https://reviews.llvm.org/D69507

To prevent AArch64 tests from running when the target is not compiled. Fixes r371502: /home/buildslave/ps4-buildslave4/llvm-clang-lld-x86_64-scei-ps4-ubuntu-fast/llvm.src/test/Transforms/ExpandMemCmp/AArch64/memcmp.ll:11:15: error: CHECK-NEXT: expected string not found in input ; CHECK-NEXT: [[TMP0:%.*]] = bitcast i8* [[S1:%.*]] to i64* llvm-svn: 371503

This allows later passes (in particular InstCombine) to optimize more cases. One that's important to us is `memcmp(p, q, constant) < 0` and memcmp(p, q, constant) > 0. llvm-svn: 364412

As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
