Subject: For Thumb indirect branches, use "mov pc, reg" which does not switch
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=af14e663ac9bbdd8b545552da60fe807754c9988;p=oota-llvm.git

For Thumb indirect branches, use "mov pc, reg" which does not switch
between ARM/Thumb modes and does not require the low bit of the target
address to be set for Thumb.
