whether the constant is signed or unsigned, then casting

Chris Lattner 98fa07b1d5 Fix Bug: Linker/2003-04-26-NullPtrLinkProblem.ll 
This was a problem with constants having their types resolved to some new type,
but there was already a constant of the new type created.  Before, these types
were never merged together, now they are.

 2003-03-06 21:02:18 +00:00
Chris Lattner 163b890dfb - Dramatically simplify the Constant::mutateReferences implementation, 
allowing it to be called on all constant types (structures/arrays)

llvm-svn: 4160
 2002-10-14 03:30:23 +00:00
Chris Lattner 69ce8674b5 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to 
reflect the fact that it's a range being defined.

llvm-svn: 4147
 2002-10-13 19:39:16 +00:00
Chris Lattner b1dd9bbc68 - Add new Constant::replaceUsesOfWithOnConstant which has an end result 
similar to User::replaceUsesOfWith but actually does the right thing for
    constants.

llvm-svn: 4102
 2002-10-09 23:12:25 +00:00
Chris Lattner 0d779712e7 Fix bug: Assembler/2002-10-08-LargeArrayPerformance.ll by using 
std::vector::reserve when possible

 2002-09-11 01:21:04 +00:00
Chris Lattner b0b412e66e - Renamed Type::isIntegral() to Type::isInteger() 
- Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

llvm-svn: 3574
 2002-09-03 01:08:28 +00:00
Chris Lattner 81fabb05e5 Add support for turning an array of characters into a string. 
llvm-svn: 3509
 2002-08-26 17:53:56 +00:00
Chris Lattner 0c6e0b9042 - ConstantPointerRefs are now automatically removed from the module table 
when they are destroyed, which makes Constant::destroyConstant an actually
    useful external interface.  Expose these methods publicly.
  - Implement destroyConstant on ConstPointerNull so that destroyConstant can
    be used on any derived type constant safely.

llvm-svn: 3379
 2002-08-18 00:40:04 +00:00
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.

Chris Lattner 31408f7a80 Return null on failure, instead of aborting.

Chris Lattner b1585a90d9 - Rename ConstantGenericIntegral -> ConstantIntegral 
- Add new methods to ConstantIntegral: getMaxValue, getMinValue,
   getAllOnesValue

llvm-svn: 3299
 2002-08-13 17:50:20 +00:00
Chris Lattner 41e99a07f1 - Added a new superclass of ConstantBool/ConstantInt: ConstantGenericIntegral 
- Moved InstCombine: isMaxValue, isMinValue, isAllOnesValue to Constants.h

Chris Lattner 3cd8c56cbb Cleanup ConstantExpr handling: 
* Correctly delete TypeHandles in AsmParser.  In addition to not leaking
   memory, this prevents a bug that could have occurred when a type got
   resolved that the constexpr was using
 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr

Chris Lattner d9f4ac6680 * ConstExpr::getelementptr now takes a vector of Constants not Values 
* Assert things instead of printing an error and returning null.

Vikram S. Adve 4c48533b57 Ensure ConstExpr constants are unique using a 
map of <opcode, operands> to ConstExpr.

llvm-svn: 2909
 2002-07-15 18:19:33 +00:00
Vikram S. Adve 4e537b27d8 Added subclass ConstantExpr to represent expressions consructed from 
constants using operators such as cast, getelementptr, add, shl, etc.
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.
