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?
