Chris Lattner 93dea78f85 I can't believe the incompetence of the people I have to deal with around here. 
These fools don't even wrap code at 80 columns.

Oh wait, _I_ wrote that.  That explains a lot!!

Chris Lattner cd45bc4086 Fix PR 110: the constant folding code assumes that if something is not a 
constant expression, but is of (for example) ubyte type, then it is a
ConstantUInt.  This was not true for placeholders.

more efficient encoding of varargs calls, and the new varargs intrinsics.

Chris Lattner 2d05c60bac Add support for 'weak' linkage. 
For now, we translate linkonce into weak linkage in the bytecode format because
we don't have enough bits to represent it.  We will rev the bytecode version
soon anyways, so this will be fixed in the near future.

Chris Lattner fdf472a83a Ok, the "fix" for this is to do a real associative container. Symbol tables 
are ordered by name, not by slot, so the previous solution wasn't any good.
On a large testcase, this reduces time to parse from 2.17s to 1.58s.

llvm-svn: 8985
 2003-10-09 20:30:04 +00:00
Chris Lattner e7691a4520 Major refactoring of the bytecode reader. This includes the following 
changes:
  * BytecodeReader::getType(...) used to return a null pointer
    on error.  This was only checked about half the time.  Now we convert
    it to throw an exception, and delete the half that checked for error.
    This was checked in before, but psmith crashed and lost the change :(
  * insertValue no longer returns -1 on error, so callers don't need to
    check for it.
  * Substantial rewrite of InstructionReader.cpp, to use more efficient,
    simpler, data structures.  This provides another 5% speedup.  This also
    makes the code much easier to read and understand.

llvm-svn: 8984
 2003-10-09 20:22:47 +00:00
Chris Lattner bd26abdc95 Significantly clean up parsing of instructions. This exceptionizes and 
simplifies the control flow a bit.  This provides a small (~3%) speedup,
but it's primarily a cleanup exercise.

llvm-svn: 8983
 2003-10-09 18:25:19 +00:00
Chris Lattner 1e8addf890 Eliminate the instruction placeholder. Simplify a bunch of code. 
This results in no significant speedup, but does provide simpler code

llvm-svn: 8980
 2003-10-09 06:14:26 +00:00
Chris Lattner 42dce1e365 Eliminate the old LateResolveValues data structure, replacing it with a 
new, simpler, ForwardReferences data structure.  This is just the first
simple replacement, subsequent changes will improve the code more.

This simple change improves the performance of loading a file from HDF5
(contributed by Bill) from 2.36s to 1.93s, a 22% improvement.  This
presumably has to do with the fact that we only create ONE placeholder for
a particular forward referenced values, and also may be because the data
structure is much simpler.

Chris Lattner a9c297c8ea Remove a dead method 
llvm-svn: 8978
 2003-10-09 05:25:34 +00:00
Chris Lattner abf6412c09 This patch substantially simplifies and cleans up handling of basic blocks 
in the bytecode parser.  Before we tried to shoehorn basic blocks into the
"getValue" code path with other types of values.  For a variety of reasons
this was a bad idea, so this patch separates it out into its own data structure.

This simplifies the code, makes it fit in 80 columns, and is also much faster.
In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds
up bytecode parsing from taking 6.9s to taking 2.32s.  More speedups to
follow later.

Chris Lattner 428bf5abc9 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.

Writer changes:
  - We now explictly encode versioning information in the bytecode files.
  - This allows new code to read bytecode files produced by old code, but
    new bytecode files can have enhancements such as the above.  Although this
    makes the reader a bit more complex (having to deal with old formats), the
    writer only needs to be able to produce the most recent version.

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 49f4242d2b - Fix a really nasty bug in the bytecode reader that caused it to fail

    instead of a whole word.

    * Sort the list by pass name when printing

      the statistics dtors are called.

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.
