e8b6c4d380 All store instructions really want 'rd' in the first field.
Special cases: STFSRx and STXFSRx - they operate on predefined rd=0 or rd=1, and
expect %fsr as the parameter in assembly. They are disabled (since not used)
until an encoding, both for code generation and output, is chosen.

4c382415f6 Store instructions are different from other Format 3.1/3.2 instructions in that
they prefer the destination register to be last. Thus, two new classes were made
for them that accomodate for having this layout of operands (F3_1rd, F3_2rd).

2a257c6d5d * Added section A.34: Move FP register on int reg condition (FMOVr)
* Labeled sections that are not currently used in the Sparc backend as not
  requiring completion at this time.

f343fb82d0 Added MOVR (move int reg on register condition), aka comparison with zero.
None of these instructions are actually used in the Sparc backend, so no changes
were required in the instruction selector.

6f65b13ed3 SparcInstr.def: added 'r' and 'i' versions of MOV(F)cc instructions
SparcInstrSelection.cpp:
* Fixed opcodes to return correct 'i' version since the two functions are each
  only used in one place.
* Changed name of function to have an 'i' in the name to signify that they each
  return an immediate form of the opcode.
* Added a warning if either of the functions is ever used in a context which
  requires a register-version opcode.

SparcV9_F4.td: fixed class F4_3, added F4_4 and notes that F4_{1,2} need fixing
SparcV9.td: added the MOV(F)cc instructions

* Changed // comments to #ifdef 0 to maintain syntax highlighting.

d0b1d8fa42 * Broke up SparcV9.td into separate files as it was getting unmanageable
* Added some Format 4 classes, but not instructions
* Added notes on missing sections with FIXMEs
* Added RDCCR instr

45acae8fa4 Fixed ordering of elements in instructions: although the binary instructions
list (rd, rs1, imm), in that order (bit-wise), the actual assembly syntax is
instr rd, imm, rs1, and that is how they are constructed in the instruction
selector. This fixes the discrepancy.

Also fixed some comments along the same lines and fixed page numbers referring
to where instructions are described in the Sparc manual.
