[llvm-commits] Patch: Pattern matching for intrinsics

[Michael Ilseman]

Below is a patch to add some pattern matching support for intrinsics to PatternMatch.h:


Pattern matching code for intrinsics.

Provides m_Intrinsic pattern that can be templatized over the intrinsic id and bind/match operands similarly to other pattern matchers. Also provides example template specialization for bswap (m_BSwap) and example of code cleanup for its use. One motiviation for this is to ease upcoming peephole fast-math optimizations which may want to inspect into built-in intrinsics.
