2012-06-19Revert predefined decl tracking.Meador Inge
r158085 added some logic to track predefined declarations. The main reason we had predefined declarations in the input was because the __builtin_va_list declarations were injected into the preprocessor input. As of r158592 we explicitly build the __builtin_va_list declarations. Therefore the predefined decl tracking is no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158732 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Improve the specification of spellings in Attr.td.Sean Hunt
Note that this is mostly a structural patch that handles the change from the old spelling style to the new one. One consequence of this is that all AT_foo_bar enum values have changed to not be based off of the first spelling, but rather off of the class name, so they are now AT_FooBar and the like (a straw poll on IRC showed support for this). Apologies for code churn. Most attributes have GNU spellings as a temporary solution until everything else is sorted out (such as a Keyword spelling, which I intend to add if someone else doesn't beat me to it). This is definitely a WIP. I've also killed BaseCheckAttr since it was unused, and I had to go through every attribute anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158700 91177308-0d34-0410-b5e6-96231b3b80d8

It turns out SourceManager treating the "one-past-the-end" location as invalid, but then failing to set the invalid flag properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158699 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Add a -fuse-init-array option to cc1 and map to the UseInitArray targetRafael Espindola
option. On the driver, check if we are using libraries from gcc 4.7 or newer and if so pass -fuse-init-array to the frontend. The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in .ctors, so we have to use .init_array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158694 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Improve the error message when a function overload candidate is rejectedKaelyn Uhrain
because it expects a reference and receives a non-l-value. For example, given: int foo(int &); template<int x> void b() { foo(x); } clang will now print "expects an l-value for 1st argument" instead of "no known conversion from 'int' to 'int &' for 1st argument". The change in wording (and associated code to detect the case) was prompted by comment #5 in PR3104, and should be the last bit of work needed for the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158691 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-18Change -Winternal-linkage-in-inline from ExtWarn to Warning in C++.Jordan Rose
Per post-commit review, it's not appropriate to use ExtWarn in C++, because we can't prove that the inline function will actually be defined in more than one place (and thus we can't prove that this violates the ODR). This removes the warning entirely from uses in the main source file in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158689 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-18Support -Winternal-linkage-in-inline in C++ code.Jordan Rose
This includes treating anonymous namespaces like internal linkage, and allowing const variables to be used even if internal. The whole thing's been broken out into a separate function to avoid nested ifs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158683 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-18Move a few static functions from DiagnosticRenderer.cpp into SourceManager.Matt Beaumont-Gay
This simplifies the code a little bit, since these functions all took a SourceManager parameter and called a bunch of methods on it, and makes the functions available to other users. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158676 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-18Allow internal decls in inline functions if the function is in the main file.Jordan Rose
This handles the very common case of people writing inline functions in their main source files and not tagging them as inline. These cases should still behave as the user intended. (The diagnostic is still emitted as an extension.) I'm reworking this code anyway to account for C++'s equivalent restriction in [basic.def.odr]p6, but this should get some bots back to green. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158666 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-16[analyzer] Return an UnknownVal when we try to get the binding for a VLA.Jordan Rose
This happens in C++ mode right at the declaration of a struct VLA; MallocChecker sees a bind and tries to get see if it's an escaping bind. It's likely that our handling of this is still incomplete, but it fixes a crash on valid without disturbing anything else for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158587 91177308-0d34-0410-b5e6-96231b3b80d8

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.

2012-06-16[analyzer] Buffers passed to CGBitmapContextCreate can escape.Jordan Rose
Specifically, although the bitmap context does not take ownership of the buffer (unlike CGBitmapContextCreateWithData), the data buffer can be extracted out of the created CGContextRef. Thus the buffer is not leaked even if its original pointer goes out of scope, as long as - the context escapes, or - it is retrieved via CGBitmapContextGetData and freed. Actually implementing that logic is beyond the current scope of MallocChecker, so for now CGBitmapContextCreate goes on our system function exception list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158579 91177308-0d34-0410-b5e6-96231b3b80d8
