I needed a parsable copy of Intel's x86 instruction set documentation for a personal project, so I downloaded volumes 2A and 2B of the Intel® 64 and IA-32 Architectures Software Developer's Manual (which can be found here and here, respectively), and used a online PDF-to-HTML tool to transform them to HTML files. Unfortunately, the result was beyond terrible and absolutely unusable.
They say that you're never better served than by yourself, so I took the matter into my own, pdfminer-gloved hands to extract HTML pages straight from the documentation PDF themselves.
This branch is experimental. Right now, it doesn't produce any useful output.
However, it is expected to eventually do, and that output will be of much better
quality than the crappy converter/BeautifulSoup combo. Be sure to check out the
master branch if you want the final result.
The current documentation set can be found on this page.
