9 // PowerPC names the IEEE binary128 comparison soft-float routines with a "kf"
10 // infix instead of the generic "tf". The semantics are identical to the
11 // generic comparetf2.c routines; only the exported names differ. We provide
12 // them here because comparetf2.c cannot be reused via a -D rename: its libgcc
13 // compatibility aliases stringize the (unrenamed) target symbol name.

15 // __lekf2(a,b) returns -1 if a < b, 0 if a == b, 1 if a > b, 1 if NaN
16 // __gekf2(a,b) returns -1 if a < b, 0 if a == b, 1 if a > b, -1 if NaN
17 // __unordkf2(a,b) returns 1 if either operand is NaN, 0 otherwise
