This patch aims to help clang with better information so it can inline __bit_reference count function usage for both std::biset. Current clang inliner can not infer that the passed typed will be used only to select the optimized variant, it evaluates the type argument and type check as a load plus compare (although later optimization phases correctly optimized this out). It is mainly to help llvm inliner to generate better code for std::bitset count for aarch64. It helps on both runtime and code size, since if inline decides that _VSTD::count should not be inlined the vectorization will create both aligned and unaligned variants (which add both code size and runtime costs) llvm-svn: 350936 |
