2013-01-21CGDebugInfo.cpp: Fix a warning. [-Wunused-variable]NAKAMURA Takumi

2013-01-21PR14472: Preserve qualifiers while unwrapping types for debug infoDavid Blaikie
Looks like r161368 fixed this for one case but not all. This change generalizes the solution over all the unwrapping cases. Now that preserving the qualifiers is done independent of the particular type being unwrapped I won't bother adding test cases for each one but at least demonstrate that this change was necessary & sufficient to fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173002 91177308-0d34-0410-b5e6-96231b3b80d8

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
2013-01-13CGBuiltin.cpp: Fix abuse of ArrayRef in EmitOverflowIntrinsic().NAKAMURA Takumi
In ArrayRef<T>(X), X should not be temporary value. It could be rewritten more redundantly; llvm::Type *XTy = X->getType(); ArrayRef<llvm::Type *> Ty(XTy); llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, Ty); Since it is safe if both XTy and Ty are temporary value in one statement, it could be shorten; llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, ArrayRef<llvm::Type*>(X->getType())); ArrayRef<T> has an implicit constructor to create uni-entry of T; llvm::Value *Callee = CGF.CGM.getIntrinsic(IntrinsicID, X->getType()); MSVC-generated clang.exe crashed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172352 91177308-0d34-0410-b5e6-96231b3b80d8
