- Added a function to hold the stack location 
  where GP must be stored during LowerCALL
- AsmPrinter now emits directives based on
  relocation type
- PIC_ set to default relocation type (same as GCC)

llvm-svn: 42779

- Modified instruction format to handle pseudo instructions
- Added LoadAddr SDNode to load symbols.

address (not just from / to frameindexes).
- Added target hooks to unfold load / store instructions / SDNodes into separate
load, data processing, store instructions / SDNodes.

Tested with "make check"!

init_trampoline.  There is now only one
trampoline intrinsic.

Patch by Sterling Stein!

llvm-svn: 41758

Add a variant of foldMemoryOperand to fold any load / store, not just load / store from / to stack slots.

llvm-svn: 41597

Changed the stack frame layout, StackGrowsUp fits better to Mips strange stack.
Stack offset calculation bug fixed!

MipsAdd SDNode created to add support to an Add opcode which supports input flag
Added an instruction itinerary to all instruction classes
Added branches with zero cond codes
Now call clobbers all non-callee saved registers
Call w/ register support added
Added DelaySlot to branch and load instructions
Added patterns to handle all setcc, brcond/setcc and MipsAdd instructions

fixed to generate instructions (add, lui) glued!

InOperandList. This gives one piece of important information: # of results
produced by an instruction.
An example of the change:
def ADD32rr  : I<0x01, MRMDestReg, (ops GR32:$dst, GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
=>
def ADD32rr  : I<0x01, MRMDestReg, (outs GR32:$dst), (ins GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;

Fixed print immediate 
Fixed Identation on MipsISelDAGToDAG.cpp

Prologue/Epilogue support fp,ra save/restore and use the stack frame the right
way!
