re PR middle-end/35509 (builtin isinf() mismatch to compile-time substitution)
PR middle-end/35509
* builtins.c (mathfn_built_in_1): Renamed from mathfn_built_in.
Add `implicit' parameter. Handle BUILT_IN_SIGNBIT.
(mathfn_built_in): Rewrite in terms of mathfn_built_in_1.
(fold_builtin_classify): Handle BUILT_IN_ISINF_SIGN.
(fold_builtin_1): Likewise.
* builtins.def (BUILT_IN_ISINF_SIGN): New.
c-common.c (check_builtin_function_arguments): Handle
BUILT_IN_ISINF_SIGN.
* doc/extend.texi: Document __builtin_isinf_sign.
* fold-const.c (operand_equal_p): Handle COND_EXPR.
testsuite:
* gcc.dg/builtins-error.c: Test __builtin_isinf_sign.
* gcc.dg/tg-tests.h: Likewise. Mark variables volatile.
* gcc.dg/torture/builtin-isinf_sign-1.c: New test.
