            Bug ID: 83216
           Summary: [8 regression] FAIL: gcc.dg/graphite/interchange-3.c
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: thopre01 at gcc dot gnu.org
  Target Milestone: ---
            Target: arm-none-eabi

Hi,

The following tests started to fail on arm-none-eabi targets after commit
r253809:

PASS->FAIL: gcc.dg/graphite/interchange-3.c scan-tree-dump graphite "tiled"
PASS->FAIL: gcc.dg/graphite/interchange-7.c scan-tree-dump graphite "tiled"
PASS->FAIL: gcc.dg/graphite/interchange-9.c scan-tree-dump graphite "tiled"
PASS->FAIL: gcc.dg/graphite/uns-interchange-9.c scan-tree-dump graphite "tiled"

GCC was configured with:

--target=arm-none-eabi --with-newlib --with-mode=thumb --with-cpu=cortex-m3

Failure can be observed when targeting Arm Cortex-M0, Cortex-M3, Cortex-M4 and
Cortex-M7 at least.

Best regards.
