Commit For New Tool: llvm-abcd (Analysis of ByteCode Dumper). This tool
...
will (eventually) provide statistical analysis of bytecode files as well
as the ability to dump them in a low level format (slot numbers not
resolved). The purpose of this is to aid in the Type!=Value change of
bug 122. With this initial release, llvm-abcd merely dumps out the
bytecode. However, the infrastructure for separating bytecode parsing from
handling the parsing events is in place. The style chosen is similar to
SAX XML parsing where a handler object is called to handlign the parsing
events. This probably isn't useful to anyone but me right now as there is
no analysis yet, and the dumper doesn't work on every bytecode file. It
will probably be useful by the end of this week. Note that there is some
duplication of code from the bytecode reader. This was done to eliminate
errors from being introduced in the reader and to minimize the impact to
other LLVM developers. At some point, the Analyzer and the Reader will be
integrated to use the same infrastructure. Also, sorry for the minor change
to Instruction.h but I just couldn't bring myself to write code that
depends on Instruction internals.

Emit & read more compressed bytecode by not emitting a bytecodeblock for

each basic block in function. Instead, just emit a stream of instructions,

saves a fairly substantial chunk of bytecode space. In stripped, sample
cases, for example, we get this reduction in size:

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.

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.

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.

* Cleaned up code:
...
- no more passing around a string pointer to set errors
- no more returning booleans and checking for errors, we use C++ exceptions
* Broke functionality into 2 new classes, one reads from file, one from a stream
* Implemented lazy function streaming - the parser can read in a function at-a-time

* 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.
