operand by constant or invariant equivalence.

Hey,
Regression tested on aarch64-linux-gnu and found no regressions.
Built for arch64-w64-mingw32, ran target dependent tests, and
found no regressions.
Ok for master?
Thanks,
Saurabh

2 non-complex incoming edges.

* config/xtensa/xtensa.cc (constantsynth_pass1):
Change the comparison between src and SET_SRC(pat) to be performed
using rtx_equal_p rather than between references (pointer values)
directly, and adjust the destination of changes in validate_change
to eliminate the need to call gen_rtx_SET.
(constantsynth_pass2):
Fill in missing spacing in one place and changes dump file output
slightly.
2026-03-13 Takayuki 'January June' Suwa <jjsuwa_sys3175@yahoo.co.jp>
* config/xtensa/xtensa.cc (xtensa_split_operand_pair)
Move the common code from the split part of movd[if]_internal
MD patterns into this function, since this function is only
called from the split part of that patterns.
Also, during non-debug optimization, re-register new literal
pool entries with the split values themselves instead of
splitting the memory reference of the source numeric constant
placed in the pool.
(split_DI_SF_DF_const):
Rename to convert_SF_const and remove the split function of
D[IF]mode constant assignment.
(do_largeconst2):
Change the call from split_DI_SF_DF_const to convert_SF_const.
* config/xtensa/xtensa.md (movdi_internal, movdf_internal):
Reduce their split parts to just a call to xtensa_split_operand_pair.

* config/xtensa/xtensa.cc (FPreg_neg_scaled_simm12b_1):
Change the test to determine whether REAL_VALUE_TYPE is a non-
zero finite value to whether it is normal.
(FPreg_neg_scaled_simm12b):
Place the call to FPreg_neg_scaled_simm12b_1 last in the
expression to improve performance, and change the dump file
output slightly.

* config/xtensa/xtensa-passes.def (pass_xtensa_largeconst):

Rename it to do_largeconst1 and leave only the mandatory insn
transformation process.

transformation processes from the old do_largeconst.
(rest_of_handle_largeconst):
Rename to rest_of_handle_largeconst1 and change to call
do_largeconst1.

do_largeconst2.

rest_of_handle_largeconst1.
