2012-07-02In blocks, only pretend that enum constants have enum type if necessary.Jordan Rose
In C, enum constants have the type of the enum's underlying integer type, rather than the type of the enum. (This is not true in C++.) Thus, when a block's return type is inferred from an enum constant, it is incompatible with expressions that return the enum type. In r158899, I told block returns to pretend that enum constants have enum type, like in C++. Doug Gregor pointed out that this can break existing code. Now, we don't check the types of return statements until the end of the block. This lets us go back and add implicit casts in blocks with mixed enum constants and enum-typed expressions. <rdar://problem/11662489> (again) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159591 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-22Documentation cleanup:James Dennett
* Primarily fixed \param commands with names not matching any actual parameters of the documented functions. In many cases this consists just of fixing up the parameter name in the \param to match the code, in some it means deleting obsolete documentation and occasionally it means documenting the parameter that has replaced the older one that was documented, which sometimes means some simple reverse-engineering of the docs from the implementation; * Fixed \param ParamName [out] to the correct format with [out] before the parameter name; * Fixed some \brief summaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158980 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-16[AST/libclang] Fix the selector locations that are reported for aArgyrios Kyrtzidis
method definition that has its '{' attached to the method name without a space. With a method like: -(id)meth{ ..... } the logic in ObjCMethodDecl that determined the selector locations got confused because it was initialized based on an end location for '{' but that end location changed to '}' after the method was finished. Fix this by having an immutable end location for the declarator and for getLocEnd() get the end location from the body itself.

2012-06-08Warn in ObjC++ when an 'auto' variable deduces type 'id'.Jordan Rose
This could happen for cases like this: - (NSArray *)getAllNames:(NSArray *)images { NSMutableArray *results = [NSMutableArray array]; for (auto img in images) { [results addObject:img.name]; } return results; } Here the property access will fail because 'img' has type 'id', rather than, say, NSImage.

2012-05-30Disable -Wunique-enum for anonymous enums.David Blaikie
This is a large class of false positives where anonymous enums are used to declare constants (see Clang's Diagnostics.h for example). A small number of true positives could probably be found in this bucket by still warning if the anonymous enum is used in a declarator (enum { ... } x;) but so far we don't believe this to be a source of significant benefit so I haven't bothered to preserve those cases.

2012-05-10Fix an old (2009) FIXME:Rafael Espindola
// FIXME: This needs to happen before we merge declarations. Then, // let attribute merging cope with attribute conflicts. This was already being done for variables, but for functions we were merging then first and then applying the attributes. To avoid duplicating merging logic, some of the helpers in SemaDeclAttr.cpp become methods that can handle merging two attributes in one decl or inheriting attributes from one decl to another. With this change we are now able to produce errors for variables with incompatible visibility attributes or warn about unused dllimports in variables. This changes the attribute list iteration back to being in reverse source code order, as that matches what decl merging does and avoids differentiating the two cases is the merge*Attr methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156531 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-06Split mergeAvailabilityAttr out of handleAvailabilityAttr. This is importantRafael Espindola
for having a uniform logic for adding attributes to a decl. This in turn is needed to fix the FIXME: // FIXME: This needs to happen before we merge declarations. Then, // let attribute merging cope with attribute conflicts. ProcessDeclAttributes(S, NewFD, D, /*NonInheritable=*/false, /*Inheritable=*/true); The idea is that mergeAvailabilityAttr will become a method. Once attributes are processed before merging, it will be called from handleAvailabilityAttr to handle multiple attributes in one decl: void f(int) __attribute__((availability(ios,deprecated=3.0), availability(ios,introduced=2.0))); and from SemaDecl.cpp to handle multiple decls: void f(int) __attribute__((availability(ios,deprecated=3.0))); void f(int) __attribute__((availability(ios,introduced=2.0))); As a bonus, use the new structure to diagnose incompatible availability attributes added to different decls (see included testcases). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156269 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-16Implement C++11 [expr.prim.general]p3, which permits the use of 'this'Douglas Gregor
in the declaration of a non-static member function after the (optional) cv-qualifier-seq, which in practice means in the exception specification and late-specified return type. The new scheme here used to manage 'this' outside of a member function scope is more general than the Scope-based mechanism previously used for non-static data member initializers and late-parsesd attributes, because it can also handle the cv-qualifiers on the member function. Note, however, that a separate pass is required for static member functions to determine whether 'this' was used, because we might not know that we have a static function until after declaration matching. Finally, this introduces name mangling for 'this' and for the implicit 'this', which is intended to match GCC's mangling. Independent verification for the new mangling test case would be appreciated.
