These intrinsics are interesting. The descriptions on Intrinsic guide are for
immediate variant, but all compilers' implementations are register variant.
What's more, the codegen from Clang and GCC don't seem correct according to the
description of `vpsrlw zmm0, zmm0, xmm1`. They should do the same broadcast as
ICC.
Back to the question, I think the type in Clang's intrinsics match with
Intrinsic guide. They just not match each other. I guess it might be historical
reasons, so let's keep them and using cast?
================
Comment at: clang/lib/Headers/cetintrin.h:37
static __inline__ void __DEFAULT_FN_ATTRS _inc_ssp(unsigned int __a) {
- __builtin_ia32_incsspd((int)__a);
+ __builtin_ia32_incsspd((unsigned int)__a);
}
----------------
Unnecessary cast?
