Hi,

I want to delete SOFTFLOAT option to get compatibility with pmax and
arc.

Currentry, hpcmips's user-land binaries are compiled with SOFTFLOAT
option. SOFTFLOAT binaries are possibly a little faster than binaryies
with kernel floating point emulation (HARDFLOAT). But it lacks binary
compatibility with other mips little endian platforms. Because the register
usage of function calling is compleately different between SOFTFLAT and
HARDFLOAT, dinamic linking liblaries will lose. And I feel that you can
scarely profit by the performance advantage.

Any objection ?
