// PowerPC names the IEEE binary128 comparison soft-float routines with a "kf"
// infix instead of the generic "tf".  The semantics are identical to the
// generic comparetf2.c routines; only the exported names differ.  We provide
// them here because comparetf2.c cannot be reused via a -D rename: its libgcc
// compatibility aliases stringize the (unrenamed) target symbol name.
//
//   __lekf2(a,b) returns -1 if a < b, 0 if a == b, 1 if a > b, 1 if NaN
//   __gekf2(a,b) returns -1 if a < b, 0 if a == b, 1 if a > b, -1 if NaN
//   __unordkf2(a,b) returns 1 if either operand is NaN, 0 otherwise
