[PR96264] LRA: Check output insn hard regs when updating available rematerialization after the insn
Insn for rematerialization can contain a clobbered hard register. We
can not move such insn through another insn setting up the same hard
register. The patch adds such check.
gcc/ChangeLog:
PR rtl-optimization/96264
* lra-remat.c (reg_overlap_for_remat_p): Check also output insn
hard regs.
gcc/testsuite/ChangeLog:
PR rtl-optimization/96264
* gcc.target/powerpc/pr96264.c: New.
