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
2012-05-07Process attributes in the order they appear in the source code. This make clangRafael Espindola
match gcc behavior for two conflicting visibilities in the same decl. It also makes handling of dllimport/dllexport more natural. As a bonus we now warn on the dllimport in void __attribute__((dllimport)) foo13(); void __attribute__((dllexport)) foo13(); as does gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156343 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-11Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie
(Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152536 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-30Fix compiler warning about && in ||.Benjamin Kramer
This time the warning found an actual bug, we don't want to handle force_align_arg_pointer differently than __force_align_arg_pointer__. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140877 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-17Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet
that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag.

2010-08-18Generate Attr subclasses with TableGen.Sean Hunt
Now all classes derived from Attr are generated from TableGen. Additionally, Attr* is no longer its own linked list; SmallVectors or Attr* are used. The accompanying LLVM commit contains the updates to TableGen necessary for this. Some other notes about newly-generated attribute classes: - The constructor arguments are a SourceLocation and a Context&, followed by the attributes arguments in the order that they were defined in Attr.td - Every argument in Attr.td has an appropriate accessor named getFoo, and there are sometimes a few extra ones (such as to get the length of a variadic argument). Additionally, specific_attr_iterator has been introduced, which will iterate over an AttrVec, but only over attributes of a certain type. It can be accessed through either Decl::specific_attr_begin/end or the global functions of the same name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111455 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-18Also don't warn about force_align_arg_pointer on function typedefs. (This willCharles Davis
break if you declare an actual function using that typedef. Come to think of it, maybe I should make this part of the type.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96570 91177308-0d34-0410-b5e6-96231b3b80d8

Thanks, Anton! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95821 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-10Add support for the force_align_arg_pointer attribute. This is an x86-specificCharles Davis
attribute, so it uses Anton's new target-specific attribute support. It's supposed to ensure that the stack is 16-byte aligned, but since necessary support is lacking from LLVM, this is a no-op for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95820 91177308-0d34-0410-b5e6-96231b3b80d8
