Created attachment 53811
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53811&action=edit
testcase, -Os -fno-trapping-math

I changed the testcase so -fsingle-precision-constant is no longer needed; just
add the f to the end of the constants.

--- Comment #2 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
We're trying to solve op2 for:

[1,1] = NAN .UNLE_EXPR. op2

NAN needs to be special cased.

    [PR tree-optimization/107490] Handle NANs in op[12]_range.

    None of the build_<OP> functions in range-op handle NANs.  This is by
    design in order to force us to handle NANs specially, because
    "x relop NAN" makes no sense.  This patch fixes a handful of
    op[12]_range entries that weren't handling NANs.

    gcc/ChangeLog:

            * range-op-float.cc (foperator_unordered_lt::op1_range): Handle
            NANs.
            (foperator_unordered_lt::op2_range): Same.
            (foperator_unordered_le::op1_range): Same.

            (foperator_unordered_ge::op2_range): Same.

    gcc/testsuite/ChangeLog:

            * gcc.dg/tree-ssa/pr107490.c: New test.
