2013-01-16[PCH/Modules] Change how macro [re]definitions are de/serialized.Argyrios Kyrtzidis
Previously we would serialize the macro redefinitions as a list, part of the identifier, and try to chain them together across modules individually without having the info that they were already chained at definition time. Change this by serializing the macro redefinition chain and then try to synthesize the chain parts across modules. This allows us to correctly pinpoint when 2 different definitions are ambiguous because they came from unrelated modules. Fixes bogus "ambiguous expansion of macro" warning when a macro in a PCH is redefined without undef'ing it first. rdar://13016031 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172620 91177308-0d34-0410-b5e6-96231b3b80d8

attributes appertain to a declaration, even though they would be much more naturally modelled as appertaining to a function type. Previously, we would try to distribute them from the declarator to the function type, then reject them for being at an incorrect location. Now, we just distribute them as far as the declarator; the existing attribute handling code can actually apply them there just fine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172504 91177308-0d34-0410-b5e6-96231b3b80d8

This was previously added to support -[NSAutoreleasePool drain], which behaves like -release under non-GC and "please collect" under GC.

2013-01-14Switch autolinking metadata format over to actual linker options, e.g.,Douglas Gregor
!0 = metadata !{metadata !"-lautolink"} !1 = metadata !{metadata !"-framework", metadata !"autolink_framework"} referenced from llvm.module.linkoptions, e.g., !llvm.module.linkoptions = !{!0, !1, !2, !3} This conceptually moves the logic for figuring out the syntax the linker will accept from LLVM into Clang. Moreover, it makes it easier to support MSVC's #pragma comment(linker, "some option") in the future, should anyone care to do so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172441 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-14This patch addresses varargs processing for small complex types underBill Schmidt
the 64-bit PowerPC ELF ABI. The ABI requires that the real and imaginary parts of a complex argument each occupy their own doubleword. Arguments smaller than 8 bytes are right-adjusted within the doubleword. Clang expects EmitVAARG() to return a pointer to a structure in which the real and imaginary parts are packed adjacently in memory. To accomplish this, we generate code to load the code appropriately from the varargs location and pack the values into a temporary variable in the form Clang expects, returning a pointer to that structure. The test case demonstrates correct code generation for all "small" complex types on PPC64: int, short, char, and float. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172438 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-14Implement parsing, AST, (de-)serialization, and placeholder globalDouglas Gregor
metadata for linking against the libraries/frameworks for imported modules. The module map language is extended with a new "link" directive that specifies what library or framework to link against when a module is imported, e.g., link "clangAST" or link framework "MyFramework" Importing the corresponding module (or any of its submodules) will eventually link against the named library/framework. For now, I've added some placeholder global metadata that encodes the imported libraries/frameworks, so that we can test that this information gets through to the IR. The format of the data is still under discussion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172437 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-12Disable caching of visibility.Rafael Espindola
The testcase in pr14929 shows that this is extremely hard to do. If we choose to apply the attribute, that causes the visibility of some decls to change and that can happen really late (during codegen). Current gcc warns and ignores the attribute in this testcase with a warning. This suggest that the correct solution is to find a point in the compilation where we can compute the visibility and * assert it was never computed before * reject any attempts to compute it again in the future (with warnings). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172305 91177308-0d34-0410-b5e6-96231b3b80d8
