GCC and Clang for Linux, macOS and embedded targets, and Microsoft’s
compiler for Windows, and it’s only the latter that doesn’t support
inline assembler.

For the most part, the embedded targets is where performance matters,
but there’s a few places where it’s relevant on the host platforms too,
and the code I’m working on currently is one of those places.
