From f171ec0c7d084b6bb163d1466edd814cf4dcbc93 Mon Sep 17 00:00:00 2001 From: Olivier Langlois Date: Thu, 10 Oct 2013 12:35:51 -0400 Subject: Make util phexdigit array reusable class template base_uint had its own private lookup table. This is saving 256 bytes per instantiation. The result is not spectacular as bitcoin-qt has only shrinked of about 1Kb but it is still valid improvement. Also, I have replaced a for loop with a memset() call. Made CBigNum::SetHex() use the new HexDigit() function.
