Reid Spencer 621fd111b5 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.

Reid Spencer 375d78428c 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.

Reid Spencer 0b85d03b57 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.

Reid Spencer 9a91081c51 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.

 2004-08-17 00:49:03 +00:00
Reid Spencer f57b8b9e70 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!

llvm-svn: 14669
 2004-07-07 15:02:54 +00:00
Reid Spencer 8e32af06f4 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.

Reid Spencer 4e0352d8c7 - 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!

Reid Spencer b14a0a69fc Put in a place holder for describing the differences in bytecode format 
between LLVM versions. This is just a reminder so I don't forget to
document it.

 2004-05-22 05:56:41 +00:00
Reid Spencer 9acd412316 Added an initial template/overview for documentation of the LLVM Bytecode 
file format. This format is being extracted from the source code and the
small recesses of Chris' brain.
