Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: bootstrap

Reporter: marxin at gcc dot gnu.org
CC: vmakarov at gcc dot gnu.org
Target Milestone: ---
Host: i586-linux-gnu
Target: i586-linux-gnu
I see the bootstrap is broken due to:

Reverting r13-5730-gf661c0bb6371f355966a67b5ce71398e80792948 makes it work

RA: Implement reuse of equivalent memory for caller saves optimization (2nd
version)
The test pr103541.c shows opportunity to reuse memory with constant address
for
caller saves optimization for constant or pure function call. The patch
implements the memory reuse.
PR rtl-optimization/103541
PR rtl-optimization/108711
gcc/ChangeLog:
* ira.h (struct ira_reg_equiv_s): Add new field caller_save_p.
* ira.cc (validate_equiv_mem): Check memref address variance.
(no_equiv): Clear caller_save_p flag.
(update_equiv_regs): Define caller save equivalence for
valid_combine.
(setup_reg_equiv): Clear defined_p flag for caller save
equivalence.
* lra-constraints.cc (lra_copy_reg_equiv): Add new arg
call_save_p. Use caller save equivalence depending on the arg.
(split_reg): Adjust the call.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr103541.c: New.
* g++.target/i386/pr108711.C: New.
