           Summary: [10 regression][arm]
                    gcc.target/arm/unaligned-memcpy-2.c FAIL since r274986
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

  Target Milestone: ---

Since r274986, even with the patch from
https://gcc.gnu.org/ml/gcc-patches/2019-08/msg02018.html, I've noticed:

FAIL: gcc.target/arm/unaligned-memcpy-2.c scan-assembler-times ldrd 0
FAIL: gcc.target/arm/unaligned-memcpy-3.c scan-assembler-times strd 0

on target arm-none-linux-gnueabihf
--with-mode arm
--with-cpu cortex-a15
--with-fpu neon-vfpv4

When building GCC --with-mode thumb, the regressions are:
FAIL: gcc.target/arm/unaligned-memcpy-2.c scan-assembler-times ldrd 0
FAIL: gcc.target/arm/unaligned-memcpy-2.c scan-assembler-times strd 1
FAIL: gcc.target/arm/unaligned-memcpy-3.c scan-assembler-times ldrd 1
FAIL: gcc.target/arm/unaligned-memcpy-3.c scan-assembler-times strd 0
