Bug ID: 124112
Summary: FAIL: gcc.dg/vect/vect-early-break_65.c
scan-tree-dump-times vect "vectorized 1 loops" 1 for
arm-none-eabi
Product: gcc
Version: 15.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
I cannot find a single version of GCC where this test case succeeds for
arm-none-eabi.
In r15-6807-g68326d5d1a593d, the expected number of loops was changed from 0 to
1, but both before and after, it was 0 for arm-none-eabi anyway.
Running the same test on x86_64-pc-linux-gnu succeeds.
