* fold-const.c (invert_tree_comparison): Do invert ORDERED_EXPR and
UNORDERED_EXPR for floating point.
Minor protest about the ChangeLog: I think you mean "Do _not_ invert..."
No, I do mean do invert. The point of the patch is that even for floating
point and even with trapping-math, it is still safe to invert them.
Maybe I can reformulate as: "Invert ORDERED_EXPR and UNORDERED_EXPR even
for trapping floating point." ?
