Subject: Thumb2 instructions are enabled only in unified assembler mode.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d61eca533081580d56fabee38f86507d8019ca75;p=oota-llvm.git

Thumb2 instructions are enabled only in unified assembler mode.
Emit switch directive for it. I have no idea whether this is
requirement for Darwin or not.
