Also added method MachineInstrInfo::getNOPOpCode().

Original logs for PreSelection.cpp:

  revision 1.2
  date: 2002/09/17 23:50:32;  author: lattner;  state: Exp;  lines: +1 -3
  Don't put default parameter values into .cpp files, it breaks 3.x compilers

  revision 1.1
  date: 2002/09/16 15:31:13;  author: vadve;  state: Exp;
  New preselection pass that specializes LLVM code for a target machine,
  while remaining in legal portable LLVM form and preserving type
  information and type safety.

constants).  Useful for target-dependent LLVM transformations like
Preselection.

llvm-svn: 3743

constructors so passes can be inserted by TargetMachine.cpp.

llvm-svn: 3742

TargetMachine.cpp, since it is entirely machine-independent.
Also, add options to disable optional back-end passes (preselection and
instr. scheduling).

Again, including Module makes Function unnecessary.

    indexes for sequential types.

- Change getelementptr instruction to use long indexes instead of uint
    indexes for sequential types.

e.g., cast double to double.

Add UltraSparcInstrInfo::CreateZeroExtensionInstructions to help with that.

-- A few bug fixes in casting between floats and ints.
-- Use SRL reg, 0 instead of AND reg, 0xffffffff to clear high 32 bits.

llvm-svn: 3579

-- Add support for ConstantExpr constants (only cast and add operators so far)
-- Avoid generating label Bbss.bss, which sometimes came out twice.

llvm-svn: 3578

  - Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

SetOperandsForMemInstr significantly).  Load and Store
no longer have any indices.  Eliminate spurious sign-extension
on a cast to float/double.

since uint is not normally sign-extended when casting to uint64_t.

llvm-svn: 3489

Eliminated the MemAccessInst class, folding contents into GEP class.

reg and Constant instead.

llvm-svn: 3441

Eliminate bool, boolreg and boolconst nonterminals, and just use
reg and Constant instead.

no longer a separate instruction but is instead implemented with XOR.

   - Eliminate Sparc*Order classes, moving contents to Sparc*Class classes
   - get register name methods now return const char * const pointers instead
     of std::string's.
   - Added file header comments to SparcRegClassInfo.(cpp|h)
   - Moved BIG constant arrays out of SparcRegClassInfo.h, into
     SparcRegInfo.cpp.  This should allow a LOT of std::string constructors to
     not have to be called.

llvm-svn: 3295

* Removed extraneous #includes
* Fixed file headers to be consistent with the rest of LLVM
* Other minor fixes
