Chris Lattner 55a07adc36 Allow modules to have 'any' pointer size and endianness. Luckily, we had 
some space for extra flags, so we don't need to bump the revision number.

Chris Lattner 5db8194ca9 * Bug fixes: 
- Fix problems where the constant table would not get updated when
    resolving constants causes other constants to change.

Changes to the V2 bytecode format
  - Null values are implicitly encoded instead of explicitly, this makes
    things more compact!
  - More compactly represent ConstantPointerRefs
  - Bytecode files are represented as:
      Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
    instead of
      Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
    which makes a lot of things simpler.

Changes to the reader:
  - Function loading code is much simpler.  We now no longer make function
    PlaceHolderHelper objects to be replaced with real functions.

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.

 2002-11-20 18:36:02 +00:00
Chris Lattner 49f4242d2b - Fix a really nasty bug in the bytecode reader that caused it to fail 
reading bytecode files with > 255 types in them, but only when optimization
    is enabled.  This was caused by GCC shrinking an enum to a single byte
    instead of a whole word.

Chris Lattner 95fcefcb7e Wow, for some reason, when reading bytecode from stdin, we were only reading 
4 bytes at a time.  Change this to read blocks of 4k

Chris Lattner 2862d2ec71 There is no way to guarantee that constants are not forward referenced. 
Handle forward referenced constants in a general way.  This fixes bug:
Assembler/2002-10-13-ConstantEncodingProblem.llx and allows the SPEC
197.parser benchmark to be built

Chris Lattner 149376dee5 - Change Function's so that their argument list is populated when they are 
constructed.  Before, external functions would have an empty argument list,
    now a Function ALWAYS has a populated argument list.

Chris Lattner 69ce8674b5 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to

Chris Lattner c8d952ebba Fix stupid oversight of missing #include. 
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 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.

llvm-svn: 3328
 2002-08-14 18:24:09 +00:00
Chris Lattner a13a2dac7e 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
