[Bug libfortran/24313] complex sqrt function does not return principal value

[kargl at gcc dot gnu dot org]

------- Comment #4 from kargl at gcc dot gnu dot org  2005-10-11 19:56 -------
This is definitely a gcc bug.

gfortran -fdump-tree-original csqrt.f 

yields (with removal of IO crap and shorting of long constants)

MAIN__ ()
{
  complex4 y;
  complex4 x;

  x = __complex__ (0.0, -1.0e+0);
  y = __builtin_csqrtf (x);

 x = __complex__ (1.17549435082228750796873653722224e-38, -1.0e+0);
  y = __builtin_csqrtf (x);

  x = __complex__ (-1.175494350822287507968736537222e-38, -1.0e+0);
  y = __builtin_csqrtf (x);

}


Note the use of __builtin_csqrtf().
