Jack Carter 30a5982e75 Implement methods that enable expansion of load immediate
macro instruction (li) in the assembler.

We have identified three possible expansions depending on 
the size of immediate operand:
  1) for 0 ≤ j ≤ 65535.
     li d,j =>
     ori d,$zero,j

  2) for −32768 ≤ j < 0.
     li d,j =>
     addiu d,$zero,j

  3) for any other value of j that is representable as a 32-bit integer.
     li d,j =>
     lui d,hi16(j)
     ori d,d,lo16(j)

All of the above have been implemented in ths patch.

Akira Hatanaka a66d676b20 Define ADJCALLSTACKDOWN/UP nodes. These nodes are emitted regardless of whether
or not it is in mips16 mode. Define MipsPseudo (mode-independant pseudo) and

instruction class. SE stands for standard encoding.

Akira Hatanaka cdf4fd8267 This patch adds a predicate to existing mips32 and mips64 so that those
instruction encodings can be excluded during mips16 processing.

This revision fixes the issue raised by Jim Grosbach.

bool hasStandardEncoding() const { return !inMips16Mode(); }

When micromips is added it will be

bool StandardEncoding() const { return !inMips16Mode()&&  !inMicroMipsMode(); }

No additional testing is needed other than to assure that there is no regression
from this patch.

Akira Hatanaka 6bbe1f0d10 Fix bugs which were introduced when support for base+index floating point loads
and stores was added.

- SelectAddr should return false if Parent is an unaligned f32 load or store.
- Only aligned load and store nodes should be matched to select reg+imm
  floating point instructions.
- MIPS does not have support for f64 unaligned load or store instructions.

Bruno Cardoso Lopes 2312a3aaa0 Final patch that completes old JIT support for Mips:
-Fix binary codes and rename operands in .td files so that automatically
generated function MipsCodeEmitter::getBinaryCodeForInstr gives correct
encoding for instructions.
-Define new class FMem for instructions that access memory.
-Define new class FFRGPR for instructions that move data between GPR and
FPU general and control registers.
-Define custom encoder methods for memory operands, and also for size
operands of ext and ins instructions.
-Only static relocation model is currently implemented.
