llvm dev - May 2013 - [LLVMdev] How to use WhileStmt to implement while loop in LLVM

Dear All,

I have a question

How could I use WhileStmt class in Stmt.h

http://clang.llvm.org/doxygen/Stmt_8h_source.html

to implement while loop like while(i==1){} that is required to be inserted

For example, Convert x++; y++; to x++; while(i=1){} y++;

from the class's constructor:

WhileStmt(ASTContext &C, VarDecl *Var, Expr *cond, Stmt
*body,SourceLocation WL);//I know C --> 1//Var--> i//cond --> =//body
--> NOP//WL --> ??

but how to implement these terms in LLVM pass? and what's the
SourceLocation?

Thanks

Do you actually mean LLVM pass? Or are you working inside clang (for 
example, on a source code rewriter)? If so, email cfe-dev instead.

Nick

No, I need to use it in LLVM pass. Could it work?
