Hi,
This patch implements V8HI byte reverse on Power8 by vector rotation.
It should be effecient than orignial vector permute. The patch comes from
Xionghu's comments in PR. I just added a test case for it.
Bootstrapped and tested on ppc64 Linux BE and LE with no regressions.
Is this okay for

Hi Hongtao,
This patch introduces function finish_cost and
determine_suggested_unroll_factor for x86 backend, to make it be
able to suggest the unroll factor for a given loop being vectorized.
Referring to aarch64, RS6000 backends and basing on the analysis on
SPEC2017 performance evaluation

Move away from the pre-C++11 compatibility macro CONSTEXPR.
This patch is inspired by aarch64:
https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603974.html.
gcc/ChangeLog:
* config/riscv/riscv-vector-builtins-bases.cc: Replace CONSTEXPR
with constexpr
Committed, thanks for the fix!

I made a mistake in this patch. I mixed 2 commits into a single patch.
Sorry about that. Please ignore this patch. Thanks.

Both current lld and the next version of ld have an option -pdb, which
creates a PDB file which Microsoft's debuggers can use. This patch adds
a -gcodeview option, which passes this to the linker.
I do intend to expand this so it also creates the .debug$S and .debug$T
sections which would make
The Plan 9 compilers defer duplicate declaration checks until field
resolution time. Further, there is a priority order of resolution such
that field lookups first match the name, then typedef'd names before
recursing into substructures.
This enables large portions of the Plan 9 userspace and
[Jakub and other FP experts, would this be OK, or am I missing
something?]
Vax does not seem to have !flag_finite_math_only, but float_type_node
does not HONOR_NANS. The check in frange::verify_range dependend on
flag_finite_math_only, which is technically not correct since

Great! Thanks for the review. I don't have push rights currently, so I
must ask that someone else pushes this patch for me.
Have a great day!

When linking with -static-pie, we need to use rcrt0.o (and grcrt0.o for
-pg). Also, set static:crt0.o before pie:Scrt1.o, otherwise -static -pie
fails to link with Scrt1.o due to missing _DYNAMIC symbol.
Also, -static-pie needs crtbeginS.o (otherwise it contains a relocation
in read-only .text).
