Description Kazu Hirata 2005-11-28 14:32:23 UTC 
Consider

double
foo (unsigned int a)
{
  return a;
}

int
main (void)
{
  return 0;
}

When I compile and link this like so

  m68k-elf-gcc -Wl,-T,sim.ld -o test test.c

I get

  undefined reference to `__floatunsidf'

Inspection of m5200/libgcc.a reveals that it does not contain __floatunsidf.

I think this is a 4.2 regression cause by JSM's patch, could you check to see if this is a regression?
