Subject: ARM IAS: add support for the .pool directive
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6692ce18e83ee2b4116d651eb3a9a557cd6a754f;p=oota-llvm.git

ARM IAS: add support for the .pool directive

The .pool directive is an alias for the .ltorg directive used to create a
literal pool.  Simply treat .pool as if .ltorg was passed.
