Chris Lattner d3fcf42efc Fix misspelled variable

Chris Lattner 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!

Chris Lattner 51a2c3cc2d - Make sure to only keep track of mappings that the TD pass may need in the 
future.  This prevents having spurious map entries to nodes that we really
    don't care about.  This allows us to reenable the DeadNodeElim, which was
    disabled.

Chris Lattner d90e74ae13 The callee is not correct, and confuses the TD pass. Null it out.

Chris Lattner 820d971233 - Rename AnalysisUsage::preservesAll to getPreservesAll & preservesCFG to 
setPreservesCFG to be less confusing.

Chris Lattner f76087336f - Add "ResolvingCaller" to the CallSite record. This keeps track of which 
function was finally able to resolve the function call.  Adding this allows
    the TD pass to actually work right!
  - Temporarily disable dead node pruning.  This will be reenabled soon.

llvm-svn: 4251
 2002-10-21 15:32:34 +00:00
Chris Lattner 78c1e7d83c As it turns out, we don't need a fully generic mapping copy ctor, we just need 
something that maps through a std::map.  Since this simplified the client and
implementation code, do so now.

Chris Lattner 32438d8c84 Don't create a new node for every reference to a global. This caused a huge 
node explosion that doesn't help anything at all.  In previous versions of
the representation this DID help, but not anymore.

Chris Lattner 295d3ed7b8 Remove a 'using' directives from a header file. Using directives cause 
global changes, so aren't good for headers.

call instructions

Chris Lattner 5c3ce31e1f - Make DSCallSite not inherit from std::vector. Renamed methods slightly. 
Make copy ctor have two versions to avoid dealing with conditional template
    argument.  DSCallSite ctor now takes all arguments instead of taking one
    and being populated later.

Vikram S. Adve ee5fb32466 Added a first-class representation for each call site that can be 
used in the DS graphs in DSGraph.h.  With that, the special-purpose
class BUDataStructure::CallSite is no longer needed here.

Vikram S. Adve dc9e142686 Added a first-class representation for each call site that can be 
used in the DS graphs.  Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function.  The special-purpose class
BUDataStructure::CallSite is no longer needed.

Chris Lattner f10327ebce * First try at implementing TD pass this does not merge global nodes yet, 
among other things.
  * Significant rewrite of TD pass to avoid potentially N^2 algorithms if
    possible.  It is still not complete, but at least it's checked in now.
