Subject: The Mips standalone assembler intial directive support.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=acbea45573078631e116c2aa91e57d3a9cb2dde1;p=oota-llvm.git

The Mips standalone assembler intial directive support.

Actually these are just stubs for parsing the directives.
Semantic support will come later.

Test cases included
