0db5ad32d1 Document the pseudo-instruction opcodes in opcode range 56-63. These are 
used to support things like volatile load/store, tail calls, and calling
conventions without reserving space for the additional information.

ea3190bbc6 Provided opcode definitions. 
Clarified documentation of symbol tables.
Clarified definition of slot numbers.
Added the http-equiv meta tag for HTML 4.01 strict compliance.
Adjusted line lengths.
Differentiated between "type slot" and "value slot" everywhere.

ae6a2c81c2 Documented the removal of alignment in version 4 bytecode files (version 3 
was released with LLVM 1.3). Alignment of fields can add severe size to
certain kinds of functions (those with lots of long format instructions) so
we decided to do away with alignment altogether in this bc version.

aff3815ba1 Technical Corrections (thanks to Robert Mykland): 
- Define the "opcode" data type and reference the Instruction.def file
- Clean up the definition of symtab by indicating that it is composed of
  two llists.
- Fix some broken links.

3df38d5f1e Correct the documentation for the module block header which uses the long 
format instead of the short format used in other blocks.

Discrepancy noted by Robert Mykland. Thanks Robert!

c5d0621e03 An update with corrections to content as well as using a regex style 
notation that Chris' suggested to make the specification more compact and
succinct. Added a section to Describe the notation, made the VBR
description its own section, and otherwise generally cleaned things up.

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!

between LLVM versions. This is just a reminder so I don't forget to
document it.
