Author: olista01 Date: Fri Apr 27 06:56:02 2018 New Revision: 331038 URL: http://llvm.org/viewvc/llvm-project?rev=331038&view=rev Log: [ARM] Add __ARM_FEATURE_DOTPROD pre-defined macro
This adds a pre-defined macro to test if the compiler has support for the v8.2-A dot rpoduct intrinsics in AArch32 mode. The AAcrh64 equivalent has already been added by rL330229. The ACLE spec which describes this macro hasn't been published yet, but this is based on the final internal draft, and GCC has already implemented this.
