--- Comment #14 from Matt Emmerton <memmerto at ca dot ibm.com> --- I'd like to thank everyone for the great discussion so far. Here's a summary of where we are at this point. 1) sync intrinsics Useful, but with caveats. 2) cache prefetch intrinsics Implemented via __builtin_prefetch() 3) larx/stcx intrinsics Useful, but with caveats. Improvements to stcx CR handling, see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93417 4) streaming cache prefetch intrinsics See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93408
