8cedc4ffa6 * Removed `using' declaration, now use full namespace qualifier std::string 
* Simplified code by using an inline function instead of copy-pasted code

c666ae831c * Set annul bit to be 0, because the Sparc backend currently does not use it. 
* Use the name of the predict field instead of just the const 1 in the
  Instruction.

17fc21b5fa This is the real fix for the previous register allocator problem. 
Physical registers should not float around.

cf51f31c3e Add patterns for (mov R, R) (mov R, I) and subtracts. The moves are to enable 
testing, the subtracts are because I was in the neighborhood.

96704b97ca * Sort #includes, remove dupliates 
* Use .zero to emit padding between struct elements
* Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print
* Print global variable identifiers next to initializer more nicely.

128b75130d * Start using tablegen'd instruction descriptions 
* Fix bug in the createNOP method, which was not marking the operands of the
  generated XCHG as useanddef.  I don't think this method is actually used,
  so it wasn't breaking anything, but it should be fixed anyway...

eda4d9cb09 Add all arithmetic operators to ConstantExprToString(). 
Note that some generated operators (like &, | or ^) may
not be supported by the assembler -- but if they've got
this far, it's better to generate them and let the assembler decide.

4576ae1530 Put back the separate pass to decompose multi-dimensional references 
since it is *necessary* for correct code generation.  Only optional
transformations belong in the PreOpts pass (which needs to be renamed
from PreSelection to PreOpts).
