This patch causes clang to error out on the following code, which used to compile fine: $ cat f2.c typedef __attribute__((__ext_vector_type__(8))) unsigned short vector_ushort8; vector_ushort8 foo1(void) { return 1 << (vector_ushort8){7,6,5,4,3,2,1,0}; } $ clang f2.c -c clang used to transform the scaler operand to a vector operand (similar to the way gcc's vector is handled) when compiling for normal c/c++ (but printed an error message when compiling for opencl), but this patch dropped the check for LangOpts added in r230464 and changed that behavior. I don't think this was intentional? Repository: rL LLVM https://reviews.llvm.org/D21678
