Subject: Replace dregsingle operand modifier with explicit escaped curly brackets.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=c00479253b92dd79b0345e4229af62835533347c;p=oota-llvm.git

Replace dregsingle operand modifier with explicit escaped curly brackets.
For other VLDn and VSTn operations, we need to list the multiple registers
explicitly anyway, so there's no point in special-casing this one usage.
