Evan Cheng 139edae4a2 Various Thumb mode load / store isel bug fixes. 
llvm-svn: 33472
 2007-01-24 02:21:22 +00:00
Evan Cheng c0b7366cf9 - Reorg Thumb load / store instructions. Combine each rr and ri pair of 
instructions into one (e.g. tLDRrr, tLDRri -> tLDR).
- Thumb ldrsb and ldrsh only have the [reg, reg] address format. If the
  address is not an add, materialize a 0 immediate into a register and use
  it as the offset field.

Reid Spencer e63b6518fa For PR950: 
Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
   type of an function parameter was used to determine whether it should
   be sign extended or zero extended before the call. This information is
   now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
   the parameter attribute information. Although it would have been
   convenient to pass in the FunctionType itself, there isn't always one
   present in the caller. Consequently, a signedness indication for the
   result type and for each parameter was provided for in the interface
   to this method. All implementations were changed to make the adjustment
   necessary.
