Subject: Remove special handling for opaque Neon vector types.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=29dd67bc59249adef304827d68b094f5b5cfc645;p=clang

Remove special handling for opaque Neon vector types.
Clang does not wrap the vectors in structs anymore so this isn't needed.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123241 91177308-0d34-0410-b5e6-96231b3b80d8
