fp-bit.c:744: error: unrecognizable insn:

This needs to match one of the call_value patterns in the rs6000.md file. Presumably the call_value_local32 pattern. The matching happens in recog. You could put a breakpoint there, and try stepping through the code to see what is wrong. You can print rtl by using the pr gdb macro. E.g.
print insn
pr
call_value_local32 doesn't do much, so I'd guess it is the current_file_function_operand predicate. You could try putting a breakpoint there also.
