--- Comment #10 from Dimitri John Ledkov <dimitri.ledkov at surgut dot co.uk> --- I agree that this is not a bug in GCC. But users are in pain and github is full of bug reports against random projects from many users claiming that nothing works. https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html is already full of documentation about various vendors, their cpus, features, and buggy features or missing implementation. The only ask I have, is to mention that one more vendor which has roughly 20% market share of new machines shipped in the last 12 months is also mentioned for the one instruction that is expected to be there, but actually is not. Because it otherwise implements and document usage of instructions that are higher/newer than SAHF. There are 28 mentions of SAHF on that page in relation to various vendors and their products. Is a one-line additional documentation, about one more vendor, is too much to ask?
