Chris Lattner 675e7a9e3d - Fighting with linking problem due to removing the ::ID elements. Now the 
implementation .cpp files for analyses are not being included into gccas
    and friends because it is linking to the .a file and there is no explicit
    symbol reference to bring in the .o file.  The new IncludeFile hack is the
    result.

Chris Lattner fda3b293d8 - Change constant printing to be better integrated with the rest of the

Chris Lattner 8f3acc6fde - Made GlobalDCE worklist driven, making it more successful. Now can handle

llvm-svn: 3381
 2002-08-18 01:28:30 +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

llvm-svn: 3367
 2002-08-17 22:02:41 +00:00
Chris Lattner 51fa0ef925 - Finally nailed: test/Regression/Assembler/2002-08-16-ConstExprInlined.llx 
- ParseConstantPool was resolving reference to value using the function
      slot # instead of the global slot #.
  - Bytecode reader changes:
    - Remove the failure<> template from Bytecode Reader
    - Remove extraneous #includes
    - s/method/function/ a bit
    - Eliminate the fwdRefs class that just added abstraction where it was not
      needed, making things more complex.
    - Use a vector instead of a list for function signatures.

llvm-svn: 3366
 2002-08-17 22:01:27 +00:00
Chris Lattner cfe8f53a4b Changed parser to always use parenthesis on ConstExprs to be consistent 
llvm-svn: 3363
 2002-08-16 21:17:11 +00:00
Chris Lattner 7f325cd0bc - Remove unused STRING token from lexer & parser 
- Changed parser to always use parenthesis on ConstExprs to be consistent
  - Parser now passes TRUE and FALSE tokens as a special case of the ConstExpr
    machinery instead of a special case of constant int stuff
  - Fix the AsmParser to use ValueRef ::= ConstExpr, and remove
    ResolvedVal ::= ConstExpr this allows constexprs to be used in PHI nodes

llvm-svn: 3362
 2002-08-16 21:14:40 +00:00

Vikram S. Adve 3db97eb499 Unary Not (boolean and bitwise) is no longer a separate LLVM instruction 
but is instead implemented with XOR.  Note that the InstrForest opLabels
for Not and BNot remain the same, i.e., the XOR is recognized and
represented as a (boolean or bitwise) Not when building the instruction
trees.  But these tree nodes are now binary, not unary.

llvm-svn: 3343
 2002-08-15 14:19:22 +00:00
Vikram S. Adve caed269085 Revise code generation for unary Not (boolean and bitwise), which is 
no longer a separate instruction but is instead implemented with XOR.

llvm-svn: 3342
 2002-08-15 14:17:37 +00:00
Vikram S. Adve 243f187791 Added more helper functions for binary instructions emulating 
unary Neg and Not: isNeg, isNot, getNegArgument, and getNotArgument.

llvm-svn: 3341
 2002-08-15 14:15:48 +00:00
Chris Lattner 0bb75910e2 Implement capability to fold this:

        %COND = setlt int %A, %B                ; <bool> [#uses=1]
        %result = cast bool %COND to uint               ; <uint> [#uses=1]
        ret uint %result
}
into a single cast instruction.

llvm-svn: 3339
 2002-08-14 23:21:10 +00:00
Chris Lattner 768c2b6bfe Avoid creating 'load X, 0' instead of just 'load X' 
This _trivial_ change causes GCSE and LICM to be much more effective at
hoisting loads.  Before it would not be able to eliminate 'load X' if there
was just a dominating 'load X, 0' because the expressions were not identical.

llvm-svn: 3337
 2002-08-14 22:11:52 +00:00
Chris Lattner 313fd77767 Avoid inserting an entry block unless we need it 
llvm-svn: 3336
 2002-08-14 21:35:02 +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 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.

llvm-svn: 3295
