re PR middle-end/19775 (sqrt(pow(x,y)) != pow(x,y*0.5) (with -ffast-math))
2005-02-07 Richard Guenther <rguenth@gcc.gnu.org>
PR middle-end/19775
* builtins.c (fold_builtin_sqrt): Transform
sqrt(pow(x,y)) to pow(fabs(x),y*0.5), not
pow(x,y*0.5).
* gcc.dg/torture/builtin-power-1.c: Disable test for
invalid transformation.
* gcc.dg/builtins-10.c: Likewise. Disable one test we
no longer optimize.
* gcc.dg/builtins-47.c: New testcase.
