David Chase 8eec2bbfbc cmd/compile: added some intrinsics to SSA back end ... One intrinsic was needed to help get the very best performance out of a future GC; as long as that one was being added, I also added Bswap since that is sometimes a handy thing to have. I had intended to fill out the bit-scan intrinsic family, but the mismatch between the "scan forward" instruction and "count leading zeroes" was large enough to cause me to leave it out -- it poses a dilemma that I'd rather dodge right now. These intrinsics are not exposed for general use. That's a separate issue requiring an API proposal change ( https://github.com/golang/proposal ) All intrinsics are tested, both that they are substituted on the appropriate architecture, and that they produce the expected result.
