Hello
This patch adds support for the unordered floating-point comparison
operators (UNEQ, UNGE, UNGT, UNLE, UNLT), which return true if one of
the operands is a NaN. These comparisons can be generated by builtins
such as __builtin_isgreater.
GCC 10 appears to have a fall-back if the unordered comparisons are not
available (by generating an unordered comparison first, followed by the
main comparison), whereas previous versions would simply throw an ICE.
Still, it should be a little more efficient to have direct support for
these operators.
Tested on a GCN3 board with no regressions noted. Okay for trunk?
OK, thanks.
