Owen Anderson 4187801f85 Template DominatorTreeBase by node type. This is the next major step towards
having dominator information on MBB's.

Owen Anderson 8313e75ea7 Completely merge the implementation details of DomTree and PostDomTree.
Also, add a FIXME for a bug in PostDomTree calculation I noticed while writing this,

2007-09-28 01:23:47 +00:00
Owen Anderson 15efb43db7 Factor the calculation details for PostDomTree out of PostDominators.cpp and
into a separate header file.

Next step: merging PostDominatorCalculation.h with DominatorCalculation.h.

Chris Lattner c63d4c2e4e reimplement dfs number computation to be significantly faster. This speeds up
natural loop canonicalization (which does many cfg xforms) by 4.3x, for 
example.  This also fixes a bug in postdom dfnumber computation.

Chris Lattner d2eb0c9653 Fix an iterator invalidation bug I induced.
llvm-svn: 40830
2007-08-05 00:24:30 +00:00
Chris Lattner 0e8f85f87e Switch some std::sets to SmallPtrSet. This speeds up
domtree by 10% and postdomtree by 17%

llvm-svn: 40829
2007-08-05 00:15:57 +00:00
Chris Lattner 77e05fe20d Switch the internal "Info" map from an std::map to a DenseMap. This
speeds up idom by about 45% and postidom by about 33%.

Some extra precautions must be taken not to invalidate densemap iterators.

llvm-svn: 40827
2007-08-05 00:02:00 +00:00
Chris Lattner bd0fe01daf switch the DomTreeNodes and IDoms maps in idom/postidom to a
DenseMap instead of an std::map.  This speeds up postdomtree
by about 25% and domtree by about 23%.  It also speeds up clients,
for example, domfrontier by 11%, mem2reg by 4% and ADCE by 6%.

Devang Patel 8c78a0bff0 Drop 'const'
llvm-svn: 36662
2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'.
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652
2007-05-02 21:39:20 +00:00
Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager.

llvm-svn: 36094
2007-04-15 23:14:18 +00:00
Owen Anderson f35a1dbc7a Remove ImmediateDominator analysis. The same information can be obtained from DomTree. A lot of code for
constructing ImmediateDominator is now folded into DomTree construction.

This is part of the ongoing work for PR217.

reduce amount of stack space used at runtime.

Reid Spencer be535661cc For PR780:
1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files
   with the macros in IncludeFile.h
This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.

llvm-svn: 28715
2006-06-07 22:00:26 +00:00
Reid Spencer 5861659a1e Change from using a stub function to a stub variable for passing to the
IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.

Nate Begeman d5811b965d Fix PR681 by using the standard Lengauer and Tarjan algorithm for dominator
set construction, rather than intersecting various std::sets.  This reduces
the memory usage for the testcase in PR681 from 496 to 26MB of ram on my
darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a
2.5GHz G5.  This also enables future code sharing between Dom and PostDom
now that they share near-identical implementations.
