I have some questions to ask: 1. How does GCC support Sapphrie Rapids CPU now? 2. Does GCC 11 fully support all the features of SPR? From the release note, it seems that 5g ISA (fp16)/hfni is not supported yet. 3. What is the simulation tool used by GCC to verify SPR characteristics? Is it open source? Thanks for all the help, yancheng ^ permalink raw reply [flat|nested] 4+ messages in thread

Intel is doing the patching to GCC and binutils so I suspect they verify using their internal tools and I highly doubt it is free source.
