            Bug ID: 61230
           Summary: [4.10 regression][AArch64] New shift costs make
                    scalar_shift_1.c to FAIL
           Product: gcc
           Version: 4.10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: christophe.lyon at st dot com

Since commit 210503 (New AArch64 costs 11/18-rotate and shifts), the
scalar_shift_1.c test now FAILs.

Tested with qemu-aarch64 on target aarch64-none-linux-gnu, and with the
Foundation Model on aarch64_be-none-elf and aarch64-none-elf.
