W/o TARGET_SSE4_1, it takes 3 instructions (pand, pandn and por) for
movdfcc/movsfcc, and could possibly fail cost comparison. Increase
branch cost could hurt performance for other modes, so specially add
some preference for floating point ifcvt.

Hi, I saw Robin commit these following patches:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=9781885a624f3e29634d95c14cd10940cefb1a5a

I think they need to be backport to GCC-14.
Any objections ? or can som

Implement a C23 clang compatible musttail attribute similar to the earlier
C++ implementation in the C parser.

When musttail is set, make tree-tailcall to give error messages
when it cannot handle a call. This avoids vague "other reasons"
error messages later at expand time.
This doesn't always work, for example when find_tail_call
walking gives up because the control flow is too complicated
then it won't
Enable the tailcall optimization for non optimizing builds,
but in this case only checks calls that have the musttail attribute set.
This makes musttail work without optimization.
This is done with a new late musttail pass that is only active when
not optimizing. The pass must be after ehcleanup.
It does nothing currently since statement attributes are handled
directly in the parser.
gcc/c-family/ChangeLog:
* c-attribs.cc (handle_musttail_attribute): Add.

Some of the cfg fixups in pro_and_epilogue for sibcalls were dependent on
"optimize".
Make them check cfun->tail_call_marked instead to handle the -O0 musttail
case. This fixes the musttail test cases on arm targets.

This patch implements a clang compatible [[musttail]] attribute for
returns.
musttail is useful as an alternative to computed goto for interpreters.
With computed goto the interpreter function usually ends up very big
which causes problems with register allocation and other per function
optimizati
This version fixes C++ template propagation of musttail, avoids ICEs for
ARM (and probably some other targets) generation of -O0 tail calls,
and improves the error messages in tree-musttail again, as well as
the documentation.
I bootstrapped/tested it on x86_64-linux, and checked the musttail test
- Give error messages for all causes of non sibling call generation
- When giving error messages clear the musttail flag to avoid ICEs
- Error out when tree-tailcall failed to mark a must-tail call
sibcall. In this case it doesn't know the true reason and only gives
a vague message.

aarch64: Additional interface function implementation.
Hello All:
All comments are addressed and patch is split into rs6000 and aarch64 target
changes.
Common infrastructure using generic code for pair mem fusion of different
targets.
rs6000 target specific code implements virtual functions defined by generic
code.
Target specific code are added
Since the patch works fine so far for mainline, ok to backport to GCC 14?
