Chris Lattner 07a5218b6e Fix testcases that used to now dead 'not' instruction

Chris Lattner 330b7ac76c Remove support for Not ConstantExpr. This simplifies the unary case to only 
have to support the cast instruction, so the function is renamed to getCast.

Vikram S. Adve 2d01206a37 Add method MachineInstr::substituteValue() which substitutes 
one Value with another one in all operands and implicit references
of the machine instruction.

Also add method MachineOperand::getVRegValueOrNull().

 2002-08-13 20:45:11 +00:00
Vikram S. Adve a3efa260ea Bug fix in TargetData::getIndexedOffset: We were using the pointer 
type instead of the element type for the element size for arrays.

Chris Lattner 56e9166b84 - Clean up interface to Sparc register handling a bit: 
- Eliminate Sparc*Order classes, moving contents to Sparc*Class classes
   - get register name methods now return const char * const pointers instead
     of std::string's.
   - Added file header comments to SparcRegClassInfo.(cpp|h)
   - Moved BIG constant arrays out of SparcRegClassInfo.h, into
     SparcRegInfo.cpp.  This should allow a LOT of std::string constructors to
     not have to be called.

Chris Lattner 41e99a07f1 - Added a new superclass of ConstantBool/ConstantInt: ConstantGenericIntegral 
- Moved InstCombine: isMaxValue, isMinValue, isAllOnesValue to Constants.h

 2002-08-12 21:20:59 +00:00
Chris Lattner 01f68c6d78 - Makefile changes: 
- Now build executables into /shared
   - New BUILD_ROOT_TOP variable which is basically = $(BUILD_ROOT)/$(LEVEL) but
     cleaner and works for llvm/test/*
   - Use := more in Makefile.common

Chris Lattner 593a74adc5 Add comment 
llvm-svn: 3287
 2002-08-12 19:18:49 +00:00
Chris Lattner 6d14f2a7ae New functionality for instcombine: 
* New ReplaceInstUsesWith function to factor out tons of common code
     This needs to be used more in the future still, but it's a good start
   * New InsertNewInstBefore to allow multi-instruction replacements
   * Change getMaxValue functions to isAllOnesValue function, which doesn't
     have to CREATE/lookup a new constant.  Also the name is accurate
   * Add new isMaxValue, isMinValue, isMaxValueMinusOne, isMinValuePlusOne
     functions:  This should be moved to Constant* classes eventually
   * Implement xor X, ALLONES -> not X
   * Fold ALL setcc's of booleans away
   * Handle various SetCC's for integers against values at the end of their
     ranges, possibly off by one.  This implements the setcc-strength-reduce.ll
     testcase.
