Hello everyone!
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.
It will be included in GCC 12 which should be released in less than 4 months.
Thank you for your reply！
3. What is the simulation tool used by GCC to verify SPR characteristics?
Is it open source?
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.
Thanks,
Andrew Pinski
Any suggestions from Intel?
Thanks!
