Subject: Add a separate NeonPolyVector kind to distinguish polynomial vector types.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=491328c90c00ecad6ad27fa0ab3cdf9195a4a820;p=clang

Add a separate NeonPolyVector kind to distinguish polynomial vector types.
Add support for mangling those types according to ARM's ABI.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118898 91177308-0d34-0410-b5e6-96231b3b80d8
