Author: sam_parker Date: Wed Aug 29 03:39:03 2018 New Revision: 340911 URL: http://llvm.org/viewvc/llvm-project?rev=340911&view=rev Log: [ARM] Set __ARM_FEATURE_SIMD32 for +dsp cores
ARM_FEATURE_DSP is already set for targets with the +dsp feature. In the backend, this target feature is also used to represent the availability of the of the instructions that the ACLE guard through the __ARM_FEATURE_SIMD32 macro. We don't have any cores that implement one and not the other, so set this macro for cores later than V6 or for Cortex-M cores that the target parser, or user, reports that the 'dsp' instructions are supported.
