toplev.c: Check for null argument to fprintf
Ensure that CF does not equal NULL in function output_stack_usage_1
before calling fprintf. This fixes the following warning/error:
gcc/toplev.c:976:13: error: argument 1 null where non-null expected [-Werror=nonnull]
976 | fprintf (cf, "\\n" HOST_WIDE_INT_PRINT_DEC " bytes (%s)",
| ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
977 | stack_usage,
| ~~~~~~~~~~~~
978 | stack_usage_kind_str[stack_usage_kind]);
An example call side where CF is NULL is in function output_stack_usage.
gcc/ChangeLog:
2020-04-30 Stefan Schulze Frielinghaus <stefansf@linux.ibm.com>
* toplev.c (output_stack_usage_1): Ensure that first
argument to fprintf is not null.
