m department, I have been working with GCC and contributed
code to the upstream repository since 2021. In September 2021, I was given
write access to the repository:
https://gcc.gnu.org/git/?p=gcc.git&a=search&h=HEAD&st=author&s=YunQiang+Su
Please let me know about your thoughts
ion like march=p6500 etc or native?
I guess the problem is about nan=2008 vs nan=legacy.
