548b9af9c2 * PIC codegen for X86/Linux has been implemented 
* PIC-aware internal structures in X86 Codegen have been refactored
* Visibility (default/weak) has been added
* Docs fixes (external weak linkage, visibility, formatting)

6e19f80688 Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

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.

Adjusted line lengths.

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.

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!
