2013-01-13Stronger respect the input codes line breaks wrt. comments.Daniel Jasper
clang-format should not change whether or not there is a line break before a line comment as this strongly influences the percieved binding. User input: void f(int a, // b is awesome int b); void g(int a, // a is awesome int b); Before: void f(int a, // b is awesome int b); void g(int a, // a is awesome int b); After: <unchanged from input> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172361 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-13Format unions like structs and classes.Daniel Jasper
Note that I don't know whether we should put {} on a single line in this case, but it is probably a theoretical issue as in practice such structs, classes or unions won't be empty. Before: union A {} a; After: union A {} a; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172355 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-13Refactor the x86 CPU name logic in the driver and pass -march and -mcpuChandler Carruth
flag information down from the Clang driver into the Gold linker plugin for LTO. This allows specifying -march on the linker commandline and should hopefully have it pass all the way through to the LTO optimizer. Fixes PR14697. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172354 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

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
2013-01-12Formatter: Initial support for formatting Objective-C method expressions. ↵Nico Weber
This follows the approach suggested by djasper in PR14911: When a '[' is seen that's at the start of a line, follows a binary operator, or follows one of : [ ( return throw, that '[' and its closing ']' are marked as TT_ObjCMethodExpr and every ':' in that range that isn't part of a ternary ?: is marked as TT_ObjCMethodExpr as well. Update the layout routines to not output spaces around ':' tokens that are marked TT_ObjCMethodExpr, and only allow breaking after such tokens, not before. Before: [self adjustButton : closeButton_ ofKind : NSWindowCloseButton]; Now: [self adjustButton:closeButton_ ofKind:NSWindowCloseButton]; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172304 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-12Fix -Wunused-comparison for comparisons in arguments to function-like macros.Matt Beaumont-Gay

2013-01-11Allow RefactoringTool to write to memory instead of always to diskEdwin Vane
RefactoringTool::run() always writes the result of rewrites to disk. Instead, make this optional and provide a method for getting the refactoring results in a memory buffer instead. Also made ClangTool polymorphic so RefactoringTool could inherit from it to properly express the IS-A relationship. This change also provides access to ClangTool's public interface, e.g. mapVirtualFile() which is important once refactored buffers start living in memory instead of on disk.
