So with the following patch (and -disable-werror) the profiledbootstrap
finishes:
@@ -75,9 +75,8 @@ const char *get_file_srcdir_relative_path (const input_file
*inpf);
static inline const char*
get_input_file_name (const input_file *inpf)
{
- if (inpf)
- return inpf->inpname;
- return NULL;
+ gcc_assert (inpf);
+ return inpf->inpname;
}
Thus, it's regression.
