f9c3f6178a It doesn't matter what the 2nd operand is; if the GEP has 2 operands and 
the first is a zero, we should leave it alone.

ef192b1a19 Add helper function. 
Don't touch GEPs for which DecomposeArrayRef is not going to do anything
special (e.g., < 2 indices, or 2 indices and the last one is a constant.)

5c1abfecfe Find bugs sooner rather than later. In this case, don't allow the creation 
of instructions that don't have a first-class or void type.

e63894ba81 Change the "rotate by 90" xtics specification to just "rotate" which is 
equivalent. The "by <angle>" syntax is not acceptable for all output
devices. Apparently the Sparc and x86 output devices (no color) don't
accept this, but should accept the plain "rotate".

bug!

4d6c479f08 Implement InstCombine/sub.ll:test15: X % -Y === X % Y 
Also, remove X % -1 = 0, because it's not true for unsigneds, and the
signed case is superceeded by this new handling.

d450ccbc91 Fix a bug in the unreachable block elim pass. Dropping all references on a 
basic block clear()'s all of the operands lists, including phis.  This
caused removePredecessor to get confused later.  Because of this, we just
nuke (without prejudice) PHI nodes in unreachable blocks.

f847cbddab - Reorganized the document contents 
- Provided a "General Layout" section that currently covers just the block
  structure of the bytecode file.
- Wrote the section on the Global Type Pool
- Wrote the section on differences between LLVM file format versions.

Only five sections left to write!

4d7e02d657 Finalize bytecode dumping. The "handleFinish" method was getting called 
too soon so the function data was not getting dumped (it was generated
after the call handleFinish). Also cleaned up the output format for
proper indentation.

93c3d80eb4 Adjust the slot machine to handle Types separately from Values. This was 
done by doubling up the data structures so that Type based equivalents are
used. A consequence of this is overloading of function members that take a
Type* instead of a Value*. Various other cleanups related to Type != Value
(bug 122) were also implemented.

373ae97a58 Implementation of SlotTable went into header file. Note that this header 
is currently not being used but is retained because it will be the basis

f15d7739d1 For bug 122: 
Separate Types from Values because Type no longer inherits from Value. The
changes for this are too numerous to list. In essence, any data structure
that contained a Value was doubled so that Types could be contained
similarly. New members include Types, TypeMap, CompactionTypes, and
CompactionTypeMap. Functions taking a Value* were overloaded with a variant
that takes a Type* that acts on the new data structures.

  the reader with a new read_typeid method and sanitizeTypeId method.
