            Bug ID: 80643
           Summary: NA->FAIL: gcc.dg/pr79214.c gcc.dg/pr79222.c
                    gcc.dg/pr79223.c
                    gcc.dg/tree-ssa/builtins-folding-gimple-ub.c
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: thopre01 at gcc dot gnu.org
                CC: msebor at gcc dot gnu.org
  Target Milestone: ---
            Target: arm-none-eabi

Hi,

The following testcases regressed or are new FAIL on arm-none-eabi targets
(such as -mcpu=cortex-m0, the last one FAILing only on that specific target) I
believe because of r247622:

NA->FAIL: gcc.dg/pr79214.c
NA->FAIL: gcc.dg/pr79222.c
NA->FAIL: gcc.dg/pr79223.c
PASS->FAIL: gcc.dg/tree-ssa/builtins-folding-gimple-ub.c
PASS->FAIL: c-c++-common/Wsizeof-pointer-memaccess2.c

Note that, unlike PASS->FAIL for gcc.dg/pr78138.c, the FAILs are still there if
I fix the obvious missing colon after the name of the function

The log for the errors is as follows:

NA->FAIL: gcc.dg/pr79214.c
