Btw. How compiler intrinsics work? I see there's only bswap declaration
(without body) in core.bitop. Where can I find compiler code which
actually substitutes bswap() into real instructions?
A complier intrinsic is a special function that the compiler replaces with
inline code. The idea is, some targets of the compiler have instructions
which implement the function, so instead of doing a function call and
inline assembly, the compiler just replaces the call to a single
instruction (in this case bswap).
So the answer is, you won't find that code anywhere :) If you grep for
bswap in the dmd source, you might find out how it does it.
