            Bug ID: 67959
           Summary: "width of 'code' exceeds its type" error in
                    ssa-thread-13
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

By declaring the field "code" in struct rtx_def

ssa-thread-13 assumes that enum rtx_code is 16-bit or more in size when
declaring the field "code" in struct rtx_def. This can only be assumed if
passing -fno-short-enums when compiling since targets are free to default to
short enum (ARM does for AAPCS based API, see arm_default_short_enums in
config/arm/arm.c).

Because of that the test is currently failing on ARM.

Thomas, in the future it'd be helpful to indicate an actual target
configuration for those not as intimately familiar with the ARM targets :-)

I went through 3 before I stumbled on on that would show this failure.

I'll be checking in a fix momentarily.

I confirm the test now passes on arm-non-eabi targets.
