Chris Lattner 98cf1f5d64 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

Chris Lattner 3cf3782bc0 Updates to work with recent Statistic's changes: 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
    * Updated ProgrammersManual with new semantics.

of instruction constructors.

Chris Lattner b0b412e66e - Renamed Type::isIntegral() to Type::isInteger()

    also accepts bool.

Chris Lattner 60ebba51c4 * Remove dead code from ExprTypeConvert.cpp 
- I->use_empty() can never be true because of the IHolder's
* Fix bug: test/Regression/Transforms/LevelRaise/2002-07-16-SourceAndDestCrash.ll
   - Add a new NewCasts member to VMC to keep track of casts that have been
     created and to ensure there is always a reference to the cast.
   - Extend ValueHandle a bit so it can be used in an STL container
   - Make sure we destroy the ValueMapCache before verifying the function
     in LevelRaise.cpp

llvm-svn: 2936
 2002-07-17 17:11:33 +00:00
Chris Lattner 5ec260a714 * Add a bunch of debugging features to LevelRaise 
- Verify the function every time it is exprconverted if DEBUG is on
  - Provide a way to start exprconversion AT a specific instruction.

llvm-svn: 2714
 2002-05-22 17:27:12 +00:00
Chris Lattner a3c3456e7f Fix a major source of "type unsafety", where a cast is neccesary, but can 
be put either before or after a load.  We chose to cast the value loaded
instead of the pointer to load from.

Fixes bug: test/Regression/Transforms/LevelRaise/2002-05-10-LoadPeephole.ll

llvm-svn: 2621
 2002-05-14 05:23:45 +00:00
Chris Lattner da2eddd5c4 * Add support for the -stats command line option to report how much is changed 
* Make cast-of-self-ty DCE the dead cast instruction immediately instead of
  waiting for it to be DCE'd by another sweep over the function.  This speeds
  this up noticably.

to make debugging output a lot nicer.

Chris Lattner c8e665431b * 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

are being converted over to Function.

Chris Lattner 0d984ef719 Fix the: test/Regression/Other/2002-03-20-LevelRaiseCrash.ll bug. It turned 
out that almost always the result of the add was the same as the GEP that
would be generated.  In this case, however, it wasn't, so bad things happened.
