Currently experiencing this on a release build of a program The instruction seems to be an SSE4a instruction, a subset only available on AMD CPUs If this instruction were supported, it would be greatly appreciated! This instruction is issued by clang in 19.0.0

I'd be interested in fixing this bug, as I am facing it again. I will take it and I'll take a look at contributing documentation
Created attachment 177871 [details] Patch to add support for the hole SSE4a instruction set (compressed due to diff being quite large at ~4MB)
Please see attached patch with the SSE4a support
Thanks for the patch. I'm busy at the moment setting up a new PC. It might take some time. I'll take a look when that's all done.

The patch builds OK with no warnings on FreeBSD with clang 18.1.6. No problems with the new tests either. OK with sourceware build macines.
