[Bug target/45476] libgcc should contain TCmode functions

[fxcoudert at gcc dot gnu dot org]

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          
Using built-in specs.
