Last change on this file since 52290 was 52290, checked in by vboxsync, 11 years ago

RTBigNum: Two assembly optimizations related to RTBigNumModExp. Use 64-bit element type on 64-bit hosts (instead of 32-bit everywhere). Fixed some bugs in the bit operations, which apparently didn't affect x86 or AMD64.
