- This patch adds in support to determine whether a particular label is valid for the hlasm variant - The label syntax being checked is that of an ordinary HLASM symbol (Reference, Chapter 2 (Coding and Structure) - Terms, Literals and Expressions - Terms - Symbols - Ordinary Symbol) - To achieve this, the virtual function isLabel defined in MCTargetAsmParser.h is made use of - The isLabel function is overridden in SystemZAsmParser for the hlasm variant, and the syntax is checked appropriately - Things remain unchanged for the att variant - Further patches will add in support to emit the label. These future patches will make use of this isLabel function Reviewed By: uweigand, Kai Differential Revision: https://reviews.llvm.org/D97748
