// NOTE cfg(all(feature = "c", ..)) indicate that compiler-rt provides an arch optimized
// implementation of that intrinsic and we'll prefer to use that

// NOTE(aapcs, aeabi, arm) ARM targets use intrinsics named __aeabi_* instead of the intrinsics
// that follow "x86 naming convention" (e.g. addsf3). Those aeabi intrinsics must adhere to the
// AAPCS calling convention (`extern "aapcs"`) because that's how LLVM will call them.
