Summary: - Similar to the workaround in fix of PR30188, skip sinking common lifetime markers of `alloca`. They are mostly left there after inlining functions in branches. Subscribers: hiraditya, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D66950 llvm-svn: 370376
Add a GISelPredicateCode to ldaxr_*. This allows us to import the patterns for @llvm.aarch64.ldaxr.*, and thus select them. Add `isLoadStoreOfNumBytes` for the GISelPredicateCode, since each of these intrinsics involves the same check. Add select-ldaxr-intrin.mir, and update arm64-ldxr-stxr.ll. Differential Revision: https://reviews.llvm.org/D66897 llvm-svn: 370377
Same thing as D66897, but for ldxr.* instead. Add a GISelPredicateCode to the ldxr_* definitions, which allows us to import them. Add select-ldxr-intrin.mir, and update arm64-ldxr-stxr.ll. Differential Revision: https://reviews.llvm.org/D66898 llvm-svn: 370378

….stlxr.* Remove manual selection code for this intrinsic and use a GISelPredicateCode instead. This allows us to fully select this intrinsic without any tricky custom C++ matching. Differential Revision: https://reviews.llvm.org/D65780 llvm-svn: 370380
