--- Comment #5 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Michal Jires <[email protected]>: https://gcc.gnu.org/g:6a3f305b298438091ef45f92553618d92a47f8dd commit r17-2420-g6a3f305b298438091ef45f92553618d92a47f8dd Author: Michal Jires <[email protected]> Date: Mon May 11 21:11:10 2026 +0200 lto: Fix cache partitioning to handle min_partition_size=0 Cache partitioning asserts that {min,max}_partition_size parameter cannot be 0 to prevent later divisions by zero. This is needlessly strict, we can clamp the value to 1 to get reasonable/expected behavior. PR lto/125257 gcc/lto/ChangeLog: * lto-partition.cc: Handle min/max_partition_size = 0 for cache partitioning. gcc/testsuite/ChangeLog: * gcc.dg/lto/pr125257_0.c: New test.
