Tried building fsf mainline on x86-darwin. Syntax error compiling c-
common.c. The preprocessed file shows the following:
if ("__builtin_" "acosf" && 1)
{ tree decl;
((void)(!((!1 && !1) || !strncmp ("__builtin_" "acosf",
"__builtin_", strlen ("__builtin_"))) ? fancy_abort ("../../gcc-
mainline/gcc/builtins.def", 162, __FUNCTION__), 0 : 0));
if (!1)
decl = lang_hooks.builtin_function ("__builtin_" "acosf",
builtin_types[BT_FN_FLOAT_FLOAT], BUILT_IN_ACOSF, BUILT_IN_NORMAL,
(1 ? ("__builtin_" "acosf" + strlen ("__builtin_")) : ((void *)0)),
built_in_attributes[(int) (flag_errno_math ? ATTR_NOTHROW_LIST :
(flag_unsafe_math_optimizations ? ATTR_CONST_NOTHROW_LIST :
ATTR_PURE_NOTHROW_NOVOPS_LIST))]);
else
decl = builtin_function_2 ("__builtin_" "acosf", "__builtin_"
"acosf" + strlen ("__builtin_"), builtin_types[BT_FN_FLOAT_FLOAT],
builtin_types[BT_FN_FLOAT_FLOAT], BUILT_IN_ACOSF, BUILT_IN_NORMAL,
1, !flag_isoc99, built_in_attributes[(int) (flag_errno_math ?
ATTR_NOTHROW_LIST : (flag_unsafe_math_optimizations ?
ATTR_CONST_NOTHROW_LIST : ATTR_PURE_NOTHROW_NOVOPS_LIST))]);
built_in_decls[(int) BUILT_IN_ACOSF] = decl;
if ()
^^^^^^
implicit_built_in_decls[(int) BUILT_IN_ACOSF] = decl;
}
Which is result of macro expansion of:
DEF_C99_C90RES_BUILTIN (BUILT_IN_ACOSF, "acosf", BT_FN_FLOAT_FLOAT,
ATTR_MATHFN_FPROUNDING_ERRNO)
in builtins.def.
