--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
/* Get the length of the string passed to fputs. If the length
can't be determined, punt. */
tree len = get_maxval_strlen (arg0, SRK_STRLEN);
if (!len
|| TREE_CODE (len) != INTEGER_CST)
return false;
And before we had a call to c_strlen.
In both cases, they both always returned a size in ssizetype.
As far as I can tell this has been broken since the merge of the tree-ssa
branch into the trunk. I have not done a "git blame" on the tree-ssa branch to
see which revision introduced this without a cast.
Confirmed.
gimple *repl = gimple_build_call (fn_fwrite, 4, arg0,
size_one_node, len, arg1);
replace_call_with_call_and_fold (gsi, repl);
Basically you need to add a fold_convert of len to size_type_node and do a
temporary if needed.
