Synopsis: optimizer bug?
State-Changed-From-To: feedback->closed
State-Changed-By: toon
State-Changed-When: Fri Feb 14 21:09:02 2003
State-Changed-Why:
This is a classical case of x86-ism.
The symptoms are:
1. Comparison of two floating point values, one computed
and one stored.
2. Works on all architectures except x86.
3. Problem goes away when adding -ffloat-store to
the compiler options.
