--- Comment #6 from Avinash Jayakar <avinashd at gcc dot gnu.org> --- (In reply to Segher Boessenkool from comment #5) > Our current code for "parity", does not do anything newer than ISA 2.05 (so, > p6), > and is mostly ISA 2.02 even, so p5. > > popcntd is an ISA 2.07 (p8) insn. But that is 12 years old already as well, > maybe we should finally make good use of its new insns? :-) Correct, I have created a patch for this, please let me know if this is OK. https://gcc.gnu.org/pipermail/gcc-patches/2025-December/702916.html Also in the p10 ISA document, popcntd is mentioned to be supported from 2.06. Thats why in comment in this patch I mentioned that, and in test case I have used power7.
