Subject: Since ARM emits inline jump tables as part of the ConstantIsland pass,
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e1102caf86c8e09387ac7ee83aae4e69d2d35fc4;p=oota-llvm.git

Since ARM emits inline jump tables as part of the ConstantIsland pass,
it should set the jump table encloding the EK_Inline. This prevents
a second, unused, copy of the table from being emitted after the function
body. PR6581.
