Bug ID: 118504
Summary: Bogus -Wstringop-overflow warning on simple memcpy
type loop
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: aoliva at gcc dot gnu.org
CC: rguenth at gcc dot gnu.org
Target Milestone: ---
Target: arm-non-eabi
This is bug 113026, but for arm-none-eabi. Same symptom, same underlying cause
(epilogue for specific iterations writing past the end of the known array
size), just different vectorizing details, and it all fits the hints at
remaining issues in comments over there. Oh, and on arm-none-eabi, it only
hits at torture options "-O3 -fomit-frame-pointer -funroll-loops -fpeel-loops
-ftracer -finline-functions" for pr113026-1.c. No -ftracer, no warning.
