| | | | | | | | | | | | The sampler handling logic in SemaInit.cpp would inadvertently treat parentheses around sampler arguments as an implicit cast, leading to an unreachable "can't implicitly cast lvalue to rvalue with this cast kind".

* [ASTImporter] Fix for import of friend class template with definition.Balazs Keri2019-08-122-4/+50
| | | | | | | | | | | | | | | | | | | | | | Summary: If there is a friend class template "prototype" (forward declaration) and later a definition for it in the existing code, this existing definition may be not found by ASTImporter because it is not linked to the prototype (under the friend AST node). The problem is fixed by looping over all found matching decls instead of break after the first found one.

* cfi-icall: Allow the jump table to be optionally made non-canonical.Peter Collingbourne2019-08-0916-18/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default behavior of Clang's indirect function call checker will replace the address of each CFI-checked function in the output file's symbol table with the address of a jump table entry which will pass CFI checks. We refer to this as making the jump table `canonical`. This property allows code that was not compiled with ``-fsanitize=cfi-icall`` to take a CFI-valid address of a function, but it comes with a couple of caveats that are especially relevant for users of cross-DSO CFI: - There is a performance and code size overhead associated with each exported function, because each such function must have an associated jump table entry, which must be emitted even in the common case where the function is never address-taken anywhere in the program, and must be used even for direct calls between DSOs, in addition to the PLT overhead. - There is no good way to take a CFI-valid address of a function written in assembly or a language not supported by Clang. The reason is that the code generator would need to insert a jump table in order to form a CFI-valid address for assembly functions, but there is no way in general for the code generator to determine the language of the function. This may be possible with LTO in the intra-DSO case, but in the cross-DSO case the only information available is the function declaration. One possible solution is to add a C wrapper for each assembly function, but these wrappers can present a significant maintenance burden for heavy users of assembly in addition to adding runtime overhead. For these reasons, we provide the option of making the jump table non-canonical with the flag ``-fno-sanitize-cfi-canonical-jump-tables``. When the jump table is made non-canonical, symbol table entries point directly to the function body. Any instances of a function's address being taken in C will be replaced with a jump table address. This scheme does have its own caveats, however. It does end up breaking function address equality more aggressively than the default behavior, especially in cross-DSO mode which normally preserves function address equality entirely. Furthermore, it is occasionally necessary for code not compiled with ``-fsanitize=cfi-icall`` to take a function address that is valid for CFI. For example, this is necessary when a function's address is taken by assembly code and then called by CFI-checking C code. The ``__attribute__((cfi_jump_table_canonical))`` attribute may be used to make the jump table entry of a specific function canonical so that the external code will end up taking a address for the function that will pass CFI checks. Fixes PR41972. Differential Revision: https://reviews.llvm.org/D65629 llvm-svn: 368495

* Add SVE opaque built-in typesRichard Sandiford2019-08-0935-6/+547
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the SVE built-in types defined by the Procedure Call Standard for the Arm Architecture: https://developer.arm.com/docs/100986/0000 It handles the types in all relevant places that deal with built-in types. At the moment, some of these places bail out with an error, including: (1) trying to generate LLVM IR for the types (2) trying to generate debug info for the types (3) trying to mangle the types using the Microsoft C++ ABI (4) trying to @encode the types in Objective C (1) and (2) are fixed by follow-on patches but (unlike this patch) they deal mostly with target-specific LLVM details, so seemed like a logically separate change. There is currently no spec for (3) and (4), so reporting an error seems like the correct behaviour for now. The intention is that the types will become sizeless types: http://lists.llvm.org/pipermail/cfe-dev/2019-June/062523.html The main purpose of the sizeless type extension is to diagnose impossible or dangerous uses of the types, such as any that would require sizeof to have a meaningful defined value. Until then, the patch sets the alignments of the types to the values specified in the link above. It also sets the sizes of the types to zero, which is chosen to be consistently wrong and shouldn't affect correctly-written code (i.e. code that would compile even with the sizeless type extension). The patch adds the common subset of functionality needed to test the sizeless type extension on the one hand and to provide SVE intrinsic functions on the other. After this patch, the two pieces of work are essentially independent.

* [AST] No longer visiting CXXMethodDecl bodies created by compiler when ↵Johan Vikstrom2019-08-093-1/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | method was default created. Summary: Clang generates function bodies and puts them in the AST for default methods if it is defaulted outside the class definition. ` struct A { A &operator=(A &&O); }; A &A::operator=(A &&O) = default; ` This will generate a function body for the `A &A::operator=(A &&O)` and put it in the AST. This body should not be visited if implicit code is not visited as it is implicit. This was causing SemanticHighlighting in clangd to generate duplicate tokens and putting them in weird places.

* clang: Diag running out of file handles while looking for filesNico Weber2019-08-081-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | clang would only print "file not found" when it's unable to find a header file. If the reason for that is a file handle leak, that's not a very useful error message. For errors that aren't in a small whitelist ("file not found", "file is directory"), print an error with the strerror() output. This changes behavior in corner cases: If clang was out of file handles while looking in one -I dir but then suddenly wasn't when looking in the next -I dir, and both directories contained a file with the desired name, previously we'd silently return the file from the second directory. For this reason, it's important to ignore "is a directory" for this new diag: if a file foo/foo exists and -I -Ifoo are passed, an include of "foo" should successfully open file "foo" in directory "foo/" instead of complaining that "./foo" is a directory. No test since we mostly hit this when there's a handle leak somewhere, and currently there isn't one. I manually tested this with the repro steps in comment 2 on the bug below. Fixes PR42524.
