builtins.def (lceil, [...]): Mark with ATTR_CONST_NOTHROW_LIST.
* builtins.def (lceil, lceilf, lceill, lfloor, lfloorf, lfloorl,
llceil, llceilf, llceill, llfloor, llfloorf, llfloorl): Mark with
ATTR_CONST_NOTHROW_LIST.
* fold-const.c (tree_expr_nonnegative_warnv_p): Handle
FIX_TRUNC_EXPR.
testsuite:
* gcc.dg/builtins-55.c: Test *lceil* and *lfloor*.
* gcc.dg/torture/builtin-attr-1.c: Likewise.
* gcc.dg/torture/builtin-convert-1.c: Likewise. Also test *lrint* and *lround*.
* gcc.dg/torture/builtin-convert-2.c: Test ceil->lceil and floor->lfloor.
* gcc.dg/torture/builtin-convert-3.c: Test *lceil* and *lfloor*.
* gcc.dg/torture/builtin-integral-1.c: Likewise.
* gcc.dg/torture/builtin-minmax-1.c: Likewise. Also test *lrint*
and *lround*. Correct macro names.
* gcc.dg/torture/builtin-nonneg-1.c: Test *lceil* and *lfloor*.
* gcc.dg/torture/builtin-rounding-1.c: Likewise.
