tlively added a comment. I believe all the feedback has now been addressed.
================ Comment at: clang/lib/Headers/wasm_simd128.h:30 +typedef long long __i64x2 __attribute__((__vector_size__(16), __aligned__(16))); +typedef unsigned long long __u64x2 + __attribute__((__vector_size__(16), __aligned__(16))); ---------------- sunfish wrote: > Since this file is already including <stdint.h>, instead of `char`, `unsigned > char`, `short`, `unsigned short`, etc., can these use `int8_t`, `uint8_t`, > `int16_t`, `uint16_t`, and so on, for clarity? Also, this would avoid any > possible behavior change under `-funsigned-char`. Unfortunately not :( This change gives errors like ``` error: cannot initialize a parameter of type '__attribute__((__vector_size__(16 * sizeof(char)))) char' (vector of 16 'char' values) with an rvalue of type '__i8x16' (vector of 16 'int8_t' values) return (v128_t)__builtin_wasm_abs_i8x16((__i8x16)a); ``` Even changing `char` to `signed char` doesn't work. I would change the builtins to use the better types, but the builtin definition system does not allow those more interesting types. This is especially annoying because `-funsigned-char` does indeed change the behavior of the comparison intrinsics. I will have to do extra work in those functions to make it work. ================ Comment at: clang/lib/Headers/wasm_simd128.h:40 +#define __REQUIRE_CONSTANT(e) \ + _Static_assert(__builtin_constant_p(e), "Expected constant") + ---------------- sunfish wrote: > In clang's xmmintrin.h, helper macros like these `__DEFAULT_FN_ATTRS` and > `__REQUIRE_CONSTANT` are `#undef`ed at the end of the file. I can do that for `__DEFAULT_FN_ATTRS` but unfortunately not for `__REQUIRE_CONSTANT` because `__REQUIRE_CONSTANT` is present in the macro expansion of `wasm_i8x16_const` and friends.
