Daniel Neilson 0ad57a67a0 Create instruction classes for identifying any atomicity of memory intrinsic. (NFC) ... Summary: For reference, see: http://lists.llvm.org/pipermail/llvm-dev/2017-August/116589.html This patch fleshes out the instruction class hierarchy with respect to atomic and non-atomic memory intrinsics. With this change, the relevant part of the class hierarchy becomes: IntrinsicInst -> MemIntrinsicBase (methods-only class) -> MemIntrinsic (non-atomic intrinsics) -> MemSetInst -> MemTransferInst -> MemCpyInst -> MemMoveInst -> AtomicMemIntrinsic (atomic intrinsics) -> AtomicMemSetInst -> AtomicMemTransferInst -> AtomicMemCpyInst -> AtomicMemMoveInst -> AnyMemIntrinsic (both atomicities) -> AnyMemSetInst -> AnyMemTransferInst -> AnyMemCpyInst -> AnyMemMoveInst This involves some class renaming: ElementUnorderedAtomicMemCpyInst -> AtomicMemCpyInst ElementUnorderedAtomicMemMoveInst -> AtomicMemMoveInst ElementUnorderedAtomicMemSetInst -> AtomicMemSetInst A script for doing this renaming in downstream trees is included below. An example of where the Any* classes should be used in LLVM is when reasoning about the effects of an instruction (ex: aliasing). --- Script for renaming AtomicMem* classes: PREFIXES="[<,([:space:]]" CLASSES="MemIntrinsic|MemTransferInst|MemSetInst|MemMoveInst|MemCpyInst" SUFFIXES="[;)>,[:space:]]" REGEX="(${PREFIXES})ElementUnorderedAtomic(${CLASSES})(${SUFFIXES})" REGEX2="visitElementUnorderedAtomic(${CLASSES})" FILES=$( grep -E "(${REGEX}|${REGEX2})" -r . | tr ':' ' ' | awk '{print $1}' | sort | uniq ) SED_SCRIPT="s~${REGEX}~\1Atomic\2\3~g" SED_SCRIPT2="s~${REGEX2}~visitAtomic\1~g" for f in $FILES; do echo "Processing: $f" sed -i ".bak" -E "${SED_SCRIPT};${SED_SCRIPT2};${EA_SED_SCRIPT};${EA_SED_SCRIPT2}" $f done Reviewers: sanjoy, deadalnix, apilipenko, anna, skatkov, mkazantsev Reviewed By: sanjoy Subscribers: hfinkel, jholewinski, arsenm, sdardis, nhaehnle, JDevlieghere, javed.absar, llvm-commits Differential Revision: https://reviews.llvm.org/D38419 llvm-svn: 316950		2017-10-30 19:51:48 +00:00
