WebAug 16, 2024 · It's unfortunate that Intel's intrinsics aren't defined as constexpr. There's no reason they couldn't be; compilers can and do evaluate them at compile time for constant-propagation and other optimizations.

WebMar 18, 2016 · Ah, that goes some way to explaining why headers with just prototypes might exist for things that are supposed to be intrinsics. The prototypes might help IDEs and stuff, but probably the MSVC compiler itself already has internal built-in definitions for them the way gcc/clang have __builtin_XYZ pre-defined. – WebApr 13, 2024 · 1 Answer Sorted by: 7 but the calls to __builtin_memcpy and __builtin_memset are replaced with imported functions in the assembly: The reason is that those instructions are not part of the core (MVP) WebAssembly instruction set, and were added later in the bulk-memory proposal.
