thing in cases involving array new. Show that many cases using initializer list constructors work, in that they parse and pass semantic analysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150316 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-11[analyzer] Malloc Checker: Report a leak when we are returning freedAnna Zaks

2012-02-10Allow implicit capture of 'this' in a lambda even when the captureDouglas Gregor
default is '=', and reword the warning about explicitly capturing 'this' in such lambdas to indicate that only explicit capture is banned. Introduce Fix-Its for this and other "save the programmer from themself" rules regarding what can be explicitly captured and what must be implicitly captured. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150256 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-10Add test from [expr.prim.lambda]p12, which deals with odr-use andDouglas Gregor
nested captures. We currently don't get odr-use correct in array bounds, so that bit is commented out while we sort out what we need to do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150255 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-10Don't introduce a lambda's operator() into the class until after weDouglas Gregor
have finished parsing the body, so that name lookup will never find anything within the closure type. Then, add this operator() and the conversion function (if available) before completing the class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150252 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-10PR11684, core issue 1417:Richard Smith
o Correct the handling of the restrictions on usage of cv-qualified and ref-qualified function types. o Fix a bug where such types were rejected in template type parameter default arguments, due to such arguments not being treated as a template type arg context. o Remove the ExtWarn for usage of such types as template arguments; that was a standard defect, not a GCC extension. o Improve the wording and unify the code for diagnosing cv-qualifiers with the code for diagnosing ref-qualifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150244 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-10Track whether a function type has a trailing return type as type sugar. Use thisRichard Smith
to pretty-print such function types better, and to fix a case where we were not instantiating templates in lexical order. In passing, move the Variadic bit from Type's bitfields to FunctionProtoType to get the Type bitfields down to 32 bits. Also ensure that we always substitute the return type of a function when substituting explicitly-specified arguments, since that can cause us to bail out with a SFINAE error before we hit a hard error in parameter substitution. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150241 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-10Fix function prolog codegen whe coerce-to type is a struct.Evgeniy Stepanov
