Bug ID: 118055
Summary: [15 Regression] gcc.dg/tree-ssa/pr83403-1.c and -2 for
CRIS and m68k since r15-6097-gee2f19b0937b5e
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: hp at gcc dot gnu.org
CC: liuhongt at gcc dot gnu.org
Target Milestone: ---
Target: cris-elf, m68k-unknown-linux-gnu
The commit r15-6097-gee2f19b0937b5e caused gcc.dg/tree-ssa/pr83403-1.c and
gcc.dg/tree-ssa/pr83403-2.c to regress for cris-elf - and also
m68k-unknown-linux-gnu from inspection of
https://gcc.gnu.org/pipermail/gcc-testresults/2024-December/832621.html and
https://gcc.gnu.org/pipermail/gcc-testresults/2024-December/832703.html like
so:
FAIL: gcc.dg/tree-ssa/pr83403-1.c scan-tree-dump-times lim2 "Executing store
motion of" 10
FAIL: gcc.dg/tree-ssa/pr83403-2.c scan-tree-dump-times lim2 "Executing store
motion of" 10
Apparently and surprisingly, this happens for no other target posted
around that time than for (CRIS and) m68k.
Possibly arm*-*-* was also affected, as the commit forces "--param
max-completely-peeled-insns=300" but with no explanation.
