Currently clang allows the following code int a; int b = (const int) a; However it does not the following code int4 a; int4 b = (const int4) a; This is because Clang compares the qualified types instead of unqualified types for vector type casting, which causes the inconsistency. This patch fixes that. Differential Revision: https://reviews.llvm.org/D38463 llvm-svn: 314802
