Akira Hatanaka 7f4c9d1429 Emit abs.s or abs.d only if -enable-no-nans-fp-math is supplied by user. 
Invalid operation is signaled if the operand of these instructions is NaN.

Akira Hatanaka e2498d014b MIPS disassembler support. 
Patch by Vladimir Medic.

 2012-04-03 02:20:58 +00:00
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.

Akira Hatanaka 2263c10946 Fix handling of double precision loads and stores when Mips1 is targeted. 
Mips1 does not support double precision loads or stores, therefore two single
precision loads or stores must be used in place of these instructions. This 
patch treats double precision loads and stores as if they are legal
instructions until MCInstLowering, instead of generating the single precision
instructions during instruction selection or Prolog/Epilog code insertion.

Without the changes made in this patch, llc produces code that has the same 
problem described in r137484 or bails out when
MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before
register allocation.
