[llvm-commits] CVS: llvm/test/Programs/SingleSource/Benchmarks/Misc/mandel.c

[Misha Brukman]

Changes in directory llvm/test/Programs/SingleSource/Benchmarks/Misc:

mandel.c updated: 1.8 -> 1.9

---
Log message:

Some platforms (e.g., MacOS X) define cabs() as:
  struct {double x, y;} z;
  double cabs(z);
cabs(z) == hypot(x,y) == sqrt(x*x+y*y), so rewrite to be more portable.

Diffs of the changes:  (+3 -3)
