Subject: Add a finishParse() callback to the targer asm parser
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6075fa1e0eba255e217095bd2573339e64de8c8d;p=oota-llvm.git

Add a finishParse() callback to the targer asm parser

This callback is invoked when the parse has finished successfuly. It
will be used to write out ARM constant pools to implement the ldr
pseudo.
