cbf828dd0d Had to comment out a line in outByte() to get it to compile because Out and tmp were
undeclared. I was not sure what Brian wanted, so I will let him fix this. But now it compiles.

efafdf8046 * Instead of re-inventing the MachineConstantPool emitter that's already given
in Emitter.cpp, just convert the Sparc version of the constant pool into
  what's already supported and inter-operate.
* Implemented a first pass at lazy function resolution in the JITResolver. That
  required adding a SparcV9CodeEmitter pointer to simplify generating
  bit-patterns of the instructions.
* SparcV9CodeEmitter now creates and destroys static TheJITResolver, which makes
  sense because the SparcV9CodeEmitter is the only user of TheJITResolver, and
  lives for the entire duration of the JIT (via PassManager which lives in VM).
* Changed all return values in the JITResolver to uint64_t because of the 64-bit
  Sparc architecture.
* Added a new version of getting the value of a GlobalValue in the
  SparcV9CodeEmitter, which now works for already-generated functions (JITted or
  library functions).
* Removed little-used and unused functions, cleaning up the internal view of the
  SparcV9CodeEmitter.

71ab329f08 I documented this file, in an attempt to understand it, with a view toward
rewriting it.  I also vacuumed out all the commented-out code and
inaccurate comments, etc.

(We need to put the mapping information in a data structure so that we can
pass it out to the JIT, instead of automagically converting it to .byte
directives.)

b54bf54065 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).

None of these instructions are actually used in the Sparc backend, so no changes

843d6933a0 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

ba6f8e274a Several bug fixes: globals in call operands were not being pulled out;
globals in some other places may not have been pulled out either;
globals in phi operands were being put just before the phi instead of
in the predecessor basic blocks.

a83804a29a Extensive changes to the way code generation occurs for function
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

f6e4dce74c Because the format of the shift instructions is `shift r, shcnt, r', the
instructions of format 3.12 and 3.13 cannot inherit from F3rdrs1, because that
implies that the two registers are the first two parameters to the instruction.

Thus I made the instructions inherit from F3rd again, and manually added an rs1
field AFTER the shcnt field in the instruction, which maps to the appropriate
place in the instruction.

The other changes are just elimination of unnecessary spaces.

d380f29377 Makefile: Make SparcV9CodeEmitter.inc depend on SparcV9_F*.td as well.
SparcV9_F3.td: F3_12 and F3_13 instructions have rd and rs1 fields. Also,
 their fields were totally screwed up. This seems to fix the problem.

35d5512f34 When TableGen finds an error in the SparcV9.td file, it exits with a non-zero
exit code. This, in turn, makes an empty file SparcV9CodeEmitter.inc, and only
much later, produces a link error because the key function that TableGen creates
isn't found.

Using a temporary file in the middle forces a good .INC file to be generated by
TableGen, and it will keep trying until you fix the input file.
