Bug ID: 124262
Summary: FAIL: gcc.dg/fold-round-1.c scan-assembler-not
link_error

Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
For arm-none-eabi, this test fails due to that the __builtin_* functions are
not always implemented.
