Chris Lattner 3a7241c13e Add support for passes to announce that they only depend on the CFG of a

Chris Lattner feede662ad * Add getPrimitiveSize method 
* Remove isPointerType, isMethodType, etc... methods.  Use isa<> instead
* Added specialization of isa for pointer types so that DerivedTypes.h doesn't
  have to be #included to use isa<PointerType>(..)

Chris Lattner 09bbb5c015 Remove unused files: This is the old induction varaible cannonicalization 
pass built on top of interval analysis

llvm-svn: 2411

Chris Lattner a452f86593 Tighten up the AnalysisUsage of lots of passes, primarily to correctly indicate whether or not they invalidate the CFG 
llvm-svn: 2385
 2002-04-28 21:26:51 +00:00
Chris Lattner ee2ff5da74 Move FunctionPass::doesNotModifyCFG to AnalysisUsage::preservesCFG() 
llvm-svn: 2384
 2002-04-28 21:25:41 +00:00
Chris Lattner 37c8667190 * Add a stub to FunctionPass so that subclasses can declare that they do not 
modify the CFG.  It currently does nothing, but will in the future.
* Changes to make the public PassManager.h be MUCH smaller, and devoid of
  implementation details.  Now PassManager is just a Pimpl class that wraps
  PassManagerT<Module>, but lib/VMCore/Pass.cpp is now the only class that
  has to #include PassManagerT.h

llvm-svn: 2334
 2002-04-27 06:57:52 +00:00
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

llvm-svn: 2333
 2002-04-27 06:56:12 +00:00

Vikram S. Adve 7447c1b750 Added functions to compute the offset of a given incoming or outgoing 
argument. These are no longer allocated as they are discovered.

llvm-svn: 2320
 2002-04-25 04:48:54 +00:00
Vikram S. Adve f0a992f0de Optional args are no longer allocated as they are discovered. 
(This can be improved to avoid making the initial pass over the method.)
Also, ensure automatic vars and reg. spills areas are not extended
if their sizes are used for computing some other offset.

llvm-svn: 2319
 2002-04-25 04:47:26 +00:00
Chris Lattner a7d90ceccb Changes to make print pass work!

llvm-svn: 2301
 2002-04-18 19:53:34 +00:00
Chris Lattner 9844d8868f Remove getStrValue method from Constant implementations. The AssemblyWriter 
now knows how to write out a constant, not the constants themselves.  This is
fixed due to the move of the AsmWriter to the VMcore library.

llvm-svn: 2297
 2002-04-18 18:51:39 +00:00

be 'Argument' instead of FunctionArgument.

llvm-svn: 2217
 2002-04-09 19:59:31 +00:00
Chris Lattner 34c925e22a Move FunctionArgument out of iOther.h into Argument.h and rename class to

llvm-svn: 2198
 2002-04-09 15:04:37 +00:00
Chris Lattner 8c7e050576 Don't leak all of the Loop objects created... 
llvm-svn: 2196
 2002-04-09 05:43:19 +00:00
Chris Lattner f8a9bfbc03 Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the 
new PrologEpilogCodeInserter.cpp file, and include the bodies of the
GetInstructionsFor(Prolog|Epilog) functions from SparcInstrSelection.cpp
into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.

llvm-svn: 2194

* Remove WriteToAssembly functions from interface
* Move operator<< definition to only allow top level operator<< on Value*'s.
  Defined in Value.h

This header file is greatly deemphasized by these changes.  Now it is only
used if custom printing through WriteTypeSymbolic or WriteAsOperand is needed.

  directly.
* Provide operator<< for values here, instead of in Assembly/Writer.h

llvm-svn: 2168
 2002-04-08 21:51:32 +00:00

because the slot calculator is already part of the VMCore library.
* Rename incorporateMethod and purgeMethod to *Function

llvm-svn: 2154
 2002-04-07 22:49:37 +00:00
Chris Lattner 6a3d2f3598 VCG output support removed because it was broken and will never be used.

 2002-04-07 22:30:17 +00:00
Chris Lattner 62b7fd136e Change references to the Method class to be references to the Function
