            Bug ID: 59290
           Summary: [ARM] regression on negdi-2.c (big-endian)
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: christophe.lyon at st dot com

Since commit 203828 (new cortexa9_extra_costs table), I have noticed a
regression on:
  gcc.target/arm/negdi-2.c scan-assembler-times mov 1
in big-endian targets:
armeb-none-linux-gnueabihf
mode: arm or thumb
cpu=cortex-a9
fpu=neon-fp16

The preceding test in the same testcase (scan-assembler-times "negs\\tr0, r0"
1) FAILs too, but it was already the case before that commit.

The testcase might need to be adapted to cope with big-endian targets.
