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.
