Subject: Thumb2 ldm/stm 'db' mnemonics don't have a '.w' suffix.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cfbb3a78dbb9f0e5de90ef2032f0ee9a7ceda8f1;p=oota-llvm.git

Thumb2 ldm/stm 'db' mnemonics don't have a '.w' suffix.

There is no 16-bit wide encoding, so the .w suffix isn't needed (indeed, isn't
documented as allowed). Also add the missing '!' token on the _UPD
variant.
