[Bug middle-end/29056] gcc.target/powerpc/ppc-negeq0-1.c fails on powerpc64

[howarth at nitro dot med dot uc dot edu]

------- Comment #5 from howarth at nitro dot med dot uc dot edu  2007-12-24 18:26 -------
Would...

/* { dg-do compile } */
/* { dg-options "-O2" } */

long foo(long x)
{
  return -(x == 0);
}

long bar(long x)
{
  long t = __builtin_clzl(x);
  return -(t>>5);
}

/* { dg-final { scan-assembler-not "cntlzw" } } */

...be an acceptable revision then. This passes on powerpc-apple-darwin9 with
gcc trunk. However I wasn't sure if the size of the shift on t in the return
statement didn't need to be changed (or eliminated)?
