C++ (Cpp) BodyContext::getMigrationContext Examples

Example #1

File: TransBlockObjCVariable.cpp Project: alexfh/clang

void BlockObjCVariableTraverser::traverseBody(BodyContext &BodyCtx) {
  MigrationPass &Pass = BodyCtx.getMigrationContext().Pass;
  llvm::DenseSet<VarDecl *> VarsToChange;

  BlockObjCVarRewriter trans(VarsToChange);
  trans.TraverseStmt(BodyCtx.getTopStmt());

  for (llvm::DenseSet<VarDecl *>::iterator
         I = VarsToChange.begin(), E = VarsToChange.end(); I != E; ++I) {
    VarDecl *var = *I;
    BlocksAttr *attr = var->getAttr<BlocksAttr>();
    if(!attr)
      continue;
    bool useWeak = canApplyWeak(Pass.Ctx, var->getType());
    SourceManager &SM = Pass.Ctx.getSourceManager();
    Transaction Trans(Pass.TA);
    Pass.TA.replaceText(SM.getExpansionLoc(attr->getLocation()),
                        "__block",
                        useWeak ? "__weak" : "__unsafe_unretained");
