I do have a couple concerns:
1. This one is MAJOR. Without using -Wstrict-aliasing, I never see warnings
about this change. I can't even begin to explain how bad that is. The gcc
programmers made a big change (that is default compile) and there isn't even a
warning by default! I wonder how many other things like this have been done.
2. Will other compilers compile this kind of code correctly?
inline bool IsNegative(float f)
{
union
{
float f;
int i;
} u;
u.f = f;
return u.i & 0x80000000;
}
