307fb1a314 Remove default operands that are never used 
llvm-svn: 4357

ca4a9d20b8 * Make MachineOperand ctors private, so MachineOperand can only be created 
by MachineInstr.
* Add a bunch of new methods to allow incremental addition of operands to the
  machine instr instance.

8c63b6897d Change MachineBasicBlock's to not be Annotations, instead they are kept as 
part of a linked list tracked by MachineFunction.  MachineBasicBlock::get
is now linear time instead of constant time, and thus is deprecated!

340bb96e64 Fairly major overhaul of MachineInstr & Operand classes 
- Inline methods that are mostly a single line anyway
  - Eliminate several methods that were never called
  - Group methods a bit more consistently

ce64eddb71 - Two minor improvements to the MachineInstr class to reduce footprint and 
overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!

f5492b0c5b Significant improvement: GEP used by a load or store no longer generates 
a separate ADD; instead just use the indexed load/store instruction!
Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).

9e5eb46362 Use vectors instead of hash_maps for issueGaps and conflictLists. 
These hash lookups were a major sink of time because they happen so often!
Also, add option to disable scheduling.

a predecessor if it has a non-zero first index and the predecessor
ends with a struct index.

than #available regs, compute the sum excluding duplicates and if that
is less than #regs, go ahead and coalesce.

  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.
