It partially does. But TC functions are missing:
$ cat a.c
typedef _Complex float __attribute__((mode(TC))) __complex128;
__complex128 foo (__complex128 z1, __complex128 z2) {
return z1 * z2; }
__complex128 bar (__complex128 z1, __complex128 z2) {
return z1 / z2; }
int main (void) {
(void) foo (0, 0);
return 0;
}
$ ./bin/gcc a.c -W -Wall
Undefined symbols:
___divtc3, referenced from:
_bar in ccqf0ZEK.o
___multc3, referenced from:
_foo in ccqf0ZEK.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
$ ./bin/gcc -v

(In reply to comment #4) and bootstrap fails at stage 1 with ld: duplicate symbol ___fixtfdi in fixtfdi_s.o and _fixtfdi_s.o That's with the patch from comment 2 (or comment 4) - but I think that's identical to the submitted patch (comment 5). -- burnus at gcc dot gnu dot org changed: What|Removed |Added CC||ubizjak at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45476
