The PDF is
http://www.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html?iid=tech_vt_tech+64-32_manuals,
Combined Volumes 2A, 2B, 2C.

With -O0 passed to the C compiler: opening the PDF takes 5.9 seconds without
the patch, 4.1 seconds with the patch. This was measured on a 4.0 GHz AMD CPU.
