Subject: Thumb .n mnemonic qualifiers can be ignored for now.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=4d23e99d2a272a4de06ee31eee6d8e501809a573;p=oota-llvm.git

Thumb .n mnemonic qualifiers can be ignored for now.

We'll need to pay attention to them when we start getting more serious about
the details of parsing thumb2 assembly.
