Subject: AL is an optional mnemonic extension for always, except in IT instructions.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9d3acaa1a015c4499595eaff529686a517c14e15;p=oota-llvm.git

AL is an optional mnemonic extension for always, except in IT instructions.
Add printMandatoryPredicateOperand() PrintMethod for IT predicate printing.

Ref: A8.3 Conditional execution
