Hi:
For avx512f scalar instructions, current builtin function like
__builtin_ia32_*{sd,ss}_round can be replaced by
__builtin_ia32_*{sd,ss}_mask_round with mask parameter set to -1. This
patch did the replacement and remove the corresponding redundant
builtins.
Bootstrap is ok, make-check ok f
This libgo patch by Svante Signell adds some Hurd portability patches
to libgo. These are from GCC PR 93020. Bootstrapped and ran Go
testsuite on x86_64-pc-linux-gnu. Committed to mainline.

Some of the comments on the BFMMLA/BFMLA[LT] patch apply here too.

That's the other patch :-)

Thanks for the patch, looks good.

If this performs well, okay for trunk. Thanks!

We can't yet vectorise conditional internal functions whose boolean
condition is fed by a data access (or more generally, by a tree of logic
ops in which all the leaves are data accesses). Although we should add
that eventually, we'd need further work to generate good-quality code.
