2020-06-12[clang] Rename Decl::isHidden() to isUnconditionallyVisible().Martin Boehme1-1/+1
Also invert the sense of the return value. As pointed out by the FIXME that this change resolves, isHidden() wasn't a very accurate name for this function. I haven't yet changed any of the strings that are output in ASTDumper.cpp / JSONNodeDumper.cpp / TextNodeDumper.cpp in response to whether isHidden() is set because a) I'm not sure whether it's actually desired to change these strings (would appreciate feedback on this), and b) In any case, I'd like to get this pure rename out of the way first, without any changes to tests. Changing the strings that are output in the various ...Dumper.cpp files will require changes to quite a few tests, and I'd like to make those in a separate change.

...enumerations from TokenKinds.def and use the new macros from TokenKinds.def to remove the hard-coded lists of traits. All the information needed to generate these enumerations is already present in TokenKinds.def. The motivation here is to be able to dump the trait spelling without hard-coding the list in yet another place. Note that this change the order of the enumerators in the enumerations (except that in the TypeTrait enumeration all unary type traits are before all binary type traits, and all binary type traits are before all n-ary type traits). Apart from the aforementioned ordering which is relied upon, after this patch no code in clang or in the various clang tools depend on the specific ordering of the enumerators. No functional changes intended. Differential Revision: https://reviews.llvm.org/D81455 Reviewed By: aaron.ballman

trivial. We previously took a shortcut by assuming that if a subobject had a trivial copy assignment operator (with a few side-conditions), we would always invoke it, and could avoid going through overload resolution. That turns out to not be correct in the presenve of ref-qualifiers (and also won't be the case for copy-assignments with requires-clauses either). Use the same logic for lazy declaration of copy-assignments that we use for all other special member functions. Previously committed as c57f8a3a20540fcf9fbf98c0a73f381ec32fce2a. This now also includes an extension of LLDB's workaround for handling special members without the help of Sema to cover copy assignments.

2020-05-27[clangd] Add access specifier information to hover contentsDaniel Martín1-7/+5
Summary: For https://github.com/clangd/clangd/issues/382 This commit adds access specifier information to the hover contents. For example, the hover information of a class field or member function will now indicate if the field or member is private, public, or protected. This can be particularly useful when a developer is in the implementation file and wants to know if a particular member definition is public or private.

2019-12-03Differentiate between the presumed and actual file when dumping the AST to JSONAaron Ballman1-3/+10
Currently, when dumping the AST to JSON, the presumed file is what is included when dumping a source location. This patch changes the behavior to instead dump the actual file, and only dump a presumed file name when it differs from the actual file. This also corrects an issue with the test script generator that would prevent it from working on Windows due to file permissions issues.
2019-11-21[DeclCXX] Remove unknown external linkage specificationsEhud Katz1-6/+0
Partial revert of r372681 "Support for DWARF-5 C++ language tags". The change introduced new external linkage languages ("C++11" and "C++14") which not supported in C++. It also changed the definition of the existing enum to use the DWARF constants. The problem is that "LinkageSpecDeclBits.Language" (the field that reserves this enum) is actually defined as 3 bits length (bitfield), which cannot contain the new DWARF constants. Defining the enum as integer literals is more appropriate for maintaining valid values. Differential Revision: https://reviews.llvm.org/D69935
2019-11-18Implement __attribute__((objc_direct)), __attribute__((objc_direct_members))Pierre Habouzit1-0/+1
__attribute__((objc_direct)) is an attribute on methods declaration, and __attribute__((objc_direct_members)) on implementation, categories or extensions. A `direct` property specifier is added (@property(direct) type name) These attributes / specifiers cause the method to have no associated Objective-C metadata (for the property or the method itself), and the calling convention to be a direct C function call. The symbol for the method has enforced hidden visibility and such direct calls are hence unreachable cross image. An explicit C function must be made if so desired to wrap them. The implicit `self` and `_cmd` arguments are preserved, however to maintain compatibility with the usual `objc_msgSend` semantics, 3 fundamental precautions are taken: 1) for instance methods, `self` is nil-checked. On arm64 backends this typically adds a single instruction (cbz x0, <closest-ret>) to the codegen, for the vast majority of the cases when the return type is a scalar. 2) for class methods, because the class may not be realized/initialized yet, a call to `[self self]` is emitted. When the proper deployment target is used, this is optimized to `objc_opt_self(self)`. However, long term we might want to emit something better that the optimizer can reason about. When inlining kicks in, these calls aren't optimized away as the optimizer has no idea that a single call is really necessary. 3) the calling convention for the `_cmd` argument is changed: the caller leaves the second argument to the call undefined, and the selector is loaded inside the body when it's referenced only. As far as error reporting goes, the compiler refuses: - making any overloads direct, - making an overload of a direct method, - implementations marked as direct when the declaration in the interface isn't (the other way around is allowed, as the direct attribute is inherited from the declaration), - marking methods required for protocol conformance as direct, - messaging an unqualified `id` with a direct method, - forming any @selector() expression with only direct selectors. As warnings: - any inconsistency of direct-related calling convention when @selector() or messaging is used, - forming any @selector() expression with a possibly direct selector. Lastly an `objc_direct_members` attribute is added that can decorate `@implementation` blocks and causes methods only declared there (and in no `@interface`) to be automatically direct. When decorating an `@interface` then all methods and properties declared in this block are marked direct.
