(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.

We now use %g1 instead since that is shared and volatile.

(2) Use intelligent multiply selection code for array allocas.
(3) Don't use cache padding for alloca'd stack slots!
(4) Bug fix in handling call arguments: was not copying sixth FP arg
    to int reg. when calling a function with no prototype.

this is a common case created by the front-end.

instructions so that (a) constant folding is done automatically before
code generation, and (b) selection does not have to deal with them.
Also, check for ConstantPointerRefs in additional to GlobalValues
when creating a GEP to load a global address.

created here.  Instead they are created in LiveRangeInfo.cpp.  This
simplifies the code here quite a bit.

needs the RegClass list to be passed in.

llvm-svn: 3963

Don't allow direct FP-to-uint conversion (must be eliminated by preselection).
Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed.

Also added method MachineInstrInfo::getNOPOpCode().

Original logs for PreSelection.cpp:

  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.

Preselection.

constructors so passes can be inserted by TargetMachine.cpp.

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

- 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.
