Thanks to Petr for the reviews - I made these changes: Patch 1: Use 0x80 to represent flag_present's 0 in the table.
Patch 2: Added a comment for the manually unrolled step 0 of uleb128, and made both get_?leb128 macros into simple expressions. Fixed the one caller who was getting a set-but-unused warning from this. Patch 3: Redid this as a smaller optimization directly on the hash lookup function. The performance gain is not as great, but it's a simpler change and doesn't increase memory use. And my spacing should be improved everywhere. :) Thanks, Josh
