8ce750145d The only clients of the slot calculator are now the asmwriter and bcwriter.
Since this really only makes sense for these two, change hte instance variable
to reflect whether we are writing a bytecode file or not.  This makes it
reasonable to add bcwriter specific stuff to it as necessary.

2cffeec014 Add a new AliassetTracker::remove method. Because we need to be able to remove
a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.

eae45cf44b The recalclulate method was a nasty hack that was once used by the -cee pass,
which never worked itself.  The cee pass still doesn't work, but it doesn't use
this method anymore anyway, so eliminate the method.

15869aa2c7 All DSGraphs keep a reference to the targetdata they are created with. This is
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.

420a8bf2b2 Rework dominator and post dominator information so that we do not have to
unify all exit nodes of a function to compute post-dominance information.
This does not work with functions that have both unwind and return nodes,
because we cannot unify these blocks.  The new implementation is better
anyway. :)

a53e3da92c (1) Added DSGraph::cloneReachableSubgraph and DSGraph::cloneReachableNodes
to clone the subgraph reachable from a set of root nodes, into the
    current graph, merging the global nodes into those in the current graph.
(2) Added DSGraph::updateFromGlobalGraph() to rematerialize nodes from the
    globals graph into the current graph in both BU and TD passes.
(3) Added hash_set<const GlobalValue*> InlinedGlobals: a set of globals to
    track which globals have been inlined into the current graph from
    callers or callees.  In the TD pass, such globals are up-to-date and
    do not need to be rematerialized from the GlobalsGraph.
(4) Added StripIncompleteBit/KeepIncompleteBit to remove incomplete bit
    when cloning nodes into the globals graph.

9971ac4a36 This is a substantial rewrite of the AliasSetTracker class which now uses
a union-find based algorithm, is significantly faster, and is more general.
It will also scale to handle call instructions correctly, which is a nice
added bonus.

This includes a new pass -print-alias-sets which can be used to show how
alias sets are formed for a particular analysis.

8f0a16eac6 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.

6aa0d62cb9 Add support for a top-down propagation pass.
Each DSGraph now keeps a list of pending callers that have not
been inlined into the function represented by that graph.
It also keeps a copy of the original call nodes before the BU pass
eliminates some of them.

b195911eab * s/method/function
* BIG CHANGE: The root of the call "graph" is considered to be the external
  node, not the "Root".  This means that users using graph iterators like
  df_begin() will start from the external node.

f57b845547 * Rename MethodPass class to FunctionPass
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well
