Chris Lattner 76a95ecad0 Convert to use an enum to access def/use/use&def information. These make 
reading code much easier than just seeing "true, false" especially when
default parameters default one but not both arguments.

Brian Gaeke e74543584a include/llvm/CodeGen/MachineInstrBuilder.h: Add addClobber() inline 
convenience method.  Fix typo in comment.
lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.
 Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
 Take out LEAVE instructions.
 32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
 Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
 Add some simple code to Printer::runOnFunction to iterate over
  MachineBasicBlocks and call X86InstrInfo::print().
lib/Target/X86/X86InstrInfo.def: Make some more instructions with
 implicit defs "Void".  Add more sign/zero extending "move" insns
 (movsx, movzx).
lib/Target/X86/X86RegisterInfo.def: Add EFLAGS as a register.

Vikram S. Adve 16eac628f4 Pass to compute various statisics related to DSGraphs. 
For now, this just computes the #indirect call sites and
the avg. #callees per indirect call site (actually it prints
both totals and the average is their ratio).

 2002-11-12 15:57:28 +00:00
Chris Lattner dcb4ac9594 Fix two bugs: 
* The globals vector was getting broken and unsorted, this caused vortex
   to get badly pessimized
 * Node offset handling was being handled really poorly, and in particular
   we were not merging types with offsets right.  This causes several graphs
   to be non-merged.

Chris Lattner 7b61563d99 * Dramatically rework liveness evaluation. 
* Implement the first step of the Globals graph: Deleting nodes from function
  graphs.  In practice, these nodes need to be moved to the globals graph, but
  this will be taken care of later.  Note that the graphs computed right now are
  not strictly correct!
