From bb96888d31d37760c86fa1aed3bbf203792185e7 Mon Sep 17 00:00:00 2001 From: Wilson Fung Date: Sat, 30 Jun 2012 11:15:07 -0800 Subject: Fixing one of the problems discovered for bug 154 (internal). - Output of 16-bit integer multiplication (IMUL.U16) writes to the entire 32-bit register if a full register (i.e. not half register such as R1L) is specified as the destination. Before, it was only storing the lower 16-bit of the product into the full register. - Modified function header to declare at least 4 predicates in cuobjdump_to_ptxplus. This will mask out the problem with the predicate registers used before initialized. - Modified register value print out: now unsigned integers display their decimal values as well.
