2009-11-30Fix PR5633 by making the preprocessor handle the case where we canChris Lattner

2009-11-25Eliminate CXXConditionDeclExpr with extreme prejudice.Douglas Gregor
All statements that involve conditions can now hold on to a separate condition declaration (a VarDecl), and will use a DeclRefExpr referring to that VarDecl for the condition expression. ForStmts now have such a VarDecl (I'd missed those in previous commits). Also, since this change reworks the Action interface for if/while/switch/for, use FullExprArg for the full expressions in those expressions, to ensure that we're emitting Note that we are (still) not generating the right cleanups for condition variables in for statements. That will be a follow-on commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89817 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-24Clean up the AST for while loops and fix several problems withDouglas Gregor
cleanups for while loops: 1) Make sure that we destroy the condition variable of a while statement each time through the loop for, e.g., while (shared_ptr<WorkInt> p = getWorkItem()) { // ... } 2) Make sure that we always enter a new cleanup scope for the body of the while loop, even when there is no compound expression, e.g., while (blah) RAIIObject raii(blah+1); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@89800 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-23Explicitly track the condition variable within an "if" statement,Douglas Gregor
rather than burying it in a CXXConditionDeclExpr (that occassionally hides behind implicit conversions). Similar changes for switch, while, and do-while will follow, then the removal of CXXConditionDeclExpr.

2009-11-21This patch implements objective-c's 'SEL' type as a built-inFariborz Jahanian
type and fixes a long-standing code gen. crash reported in at least two PRs and a radar. (radar 7405040 and pr5025). There are couple of remaining issues that I would like for Ted. and Doug to look at: Ted, please look at failure in Analysis/MissingDealloc.m. I have temporarily added an expected-warning to make the test pass. This tests has a declaration of 'SEL' type which may not co-exist with the new changes. Doug, please look at a FIXME in PCHWriter.cpp/PCHReader.cpp. I think the changes which I have ifdef'ed out are correct.
