[cfe-dev] Add new AST node

[Pisit Makpaisit]

I want to add the AST node for OpenMP statement. I create OmpStmt class that
inherit from Stmt class and add the definition in StmtNodes.td as follow

def OmpStmt : Stmt<1>;
def OmpAtomicStmt : DStmt<OmpStmt>;
def OmpBarrierStmt : DStmt<OmpStmt>;
def OmpCriticalStmt : DStmt<OmpStmt>;
def OmpFlushStmt : DStmt<OmpStmt>;
def OmpMasterStmt : DStmt<OmpStmt>;
def OmpOrderedStmt : DStmt<OmpStmt>;
def OmpParallelStmt : DStmt<OmpStmt>;
def OmpForStmt : DStmt<OmpStmt>;
def OmpSectionsStmt : DStmt<OmpStmt>;
def OmpSectionStmt : DStmt<OmpStmt>;
def OmpSingleStmt : DStmt<OmpStmt>;
def OmpTaskStmt : DStmt<OmpStmt>;
def OmpTaskwaitStmt : DStmt<OmpStmt>;
def OmpThreadprivateStmt : DStmt<OmpStmt>;

when I build project, it show error like

In file included from
/home/remixman/Desktop/llvm/tools/clang/lib/AST/../../include/clang/AST/StmtVisitor.h:111,

OmpAtomicStmt and other OpenMP Stmt class is inherit from OmpStmt. Why the
error show that? How can I fixed?



Thanks in advance
