Thanksfor preparing this! I did not see any response, but now
noticed the designated MIPS maintainer Matthew Fortune (per
gcc/MAINTAINERS) was not on copy.
Thanks for the replay. Sorry for the late response.
The first line is a bit long; can you please wrap?
Will do.
The note on hard-float targets does not seem completely clear to me:
I understand it requires glibc 2.31, but per the language it still
may not enabled by default even if in that case? What is the
situation on the default in the hard-float case?
It retains the original behavior of not using GNU-stack notes at all.
You have to use --with-glibc-version=2.31 in all stages of gcc build
to enable GNU-stack note usage.
If believe you do not have commit access, but if you share an updated
patch I can apply for you.
