Now, you can either use the RM in the FSR or specify it in the insn.
(Except for FP->int; no dynamic for that.)

These instructions handled static shift amounts >= 32. Since we have
a 6-bit shift amount field, these opcodes are no longer necessary.

|
Massive changes to gcc, binutils to support new instruction encoding.
Simulator reflects these changes.
|
|
Moved cross-compiler to /xcc/ rather than /
Added ISA sim in /sim/
Added Proxy Kernel in /pk/ (to be cleaned up)
Added opcode map to /opcodes/ (ditto)
Added documentation to /doc/
