--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2010-11-08 19:18:37 UTC ---
Reduced testcase (fails without any options, -Wwrite-strings is not needed):
__attribute__((gnu_inline, always_inline)) extern inline char *
strncpy (char *dest, const char *src, __SIZE_TYPE__ len)
{
return __builtin_strncpy (dest, src, len);
}
void
foo (char *s)
{
strncpy (s, "", 0);
}
The problem is the fold_stmt Honza added to gimplify_call_expr.
Unfortunately fold_stmt doesn't expect it is being called when still not in SSA
form. Seems
gimplify_and_update_call_from_tree
has been adjusted for that in PR45073, but
update_call_from_tree still needs doing that. Will work on it tomorrow.
