90c1474863
In ExpandFPLibCall, an assumption is made that all floating point libcalls that take integer arguments use unsigned integers. In the case of ldexp and frexp, this assumption is incorrect, leading to miscompilation and subsequent target-dependent incorrect operation. Indicate that ldexp and frexp utilize signed arguments in ExpandFPLibCall. Fixes #108904 Signed-off-by: Timothy Pearson <tpearson@solidsilicon.com>
