[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

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?
