Subject: Headers: add hint intrinsics to arm_acle.h
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=71f06af4f7951c910333ea8f40ad343f5e754d75;p=clang

Headers: add hint intrinsics to arm_acle.h

This adds the ARM ACLE hint intrinsic wrappers to arm_acle.h.  These need to be
protected with a !defined(_MSC_VER) since MSVC (and thus clang in compatibility
mode) provide these wrappers as proper builtin intrinsics.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@212891 91177308-0d34-0410-b5e6-96231b3b80d8
