Subject: Fix out of bounds access to the double regs array. Given the
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=22221ee0e33b6b992aca34c80bf3bee1fc507ff6;p=oota-llvm.git

Fix out of bounds access to the double regs array. Given the
code this looks correct, but could use review. The previous
was definitely not correct.
