Chris Lattner 63ba1aca7c Implement the "unknown flag" which mainly consists of aligning printing code

Chris Lattner a7b0d4eb08 Stop representing scalars as explicit nodes in the graph. Now the only 
nodes in the graph are memory objects, which is very nice.  This also greatly
reduces the size and memory footprint for DSGraphs.  For example, the local
DSGraph for llu went from 65 to 13 nodes with this change.  As a side bonus,
dot seems to lay out the graphs slightly better too.  :)

Chris Lattner a19a7bccc0 * Eliminate Scalar node type (renumber other node types) 
* Allow DSNodeHandle::mergeWith to work if a node handle isn't pointing to a node yet

Chris Lattner c1d8820711 * Minor optimization: when merging nodes, merge the smaller one into the 
larger one.
     * Handle the case where we are merging two nodes of different size better.

Vikram S. Adve 8c7b93f7e3 Restore support for indirect function calls (which briefly wasn't working 
after I removed annotations on MachineInstr for the CallDescriptor).

Vikram S. Adve c0724e8d92 Do not print "NEW FILES AND DIRECTORIES" unless requested separately 
because this is usually such a long list that it makes the output
useless anyway.

Disable checking exit status until we can find something more precise.
The exit status is too coarse-grain to be useful.

Misha Brukman d88a3c3c93 Refactored DSGraph.h: 
* DSGraph.h   contains DSGraph
* DSNode.h    contains DSNode (soon UDSNode and MDSNode)
* DSSupport.h contains DSCallsite, DSTypeRec, and DSNodeHandler

Chris Lattner 7d5f19886d This fixes all kinds of problems with array handling. There are still bugs to 
be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.

 2002-10-31 01:25:13 +00:00
Chris Lattner 61596ad266 Fix two problems: 
* Load Implementation can cause unaligned memory accesses, which caused
    problems for sparc.
  * cast from pointer to pointer would zero the upper 32 bits of the pointer
    which obviously causes problems on 64 bit hosts.
