* [Parser] Change parameter type from int to enumSerge Pavlov2019-08-013-4/+4
| | | | | | | | | Some parser functions accept argument of type unsigned while it is actually of type DeclSpec::TST. No functional changes. Differential Revision: https://reviews.llvm.org/D65406 llvm-svn: 367545
* [Preprocessor] Always discard body of #define if we failed to parse itIlya Biryukov2019-08-011-5/+9
| | | | | | | | | | | | | | | | | | | | Summary: Preivously we would only discard it if we failed to parse parameter lists. If we do not consume the body, parser sees tokens inside directive. In turn, this leads to spurious diagnostics and a crash in TokenBuffer, see the added tests.

* Delay emitting dllexport explicitly defaulted members until the class is ↵Hans Wennborg2019-08-012-2/+12
| | | | | | | | | | | | | | | | | | | | fully parsed (PR40006) This is similar to r245139, but that only addressed dllexported classes. It was still possible to run into the same problem with dllexported members in an otherwise normal class (see bug). This uses the same strategy to fix: delay defining the method until the whole class has been parsed. (The easiest way to see the ordering problem is in Parser::ParseCXXMemberSpecification(): it calls ParseLexedMemberInitializers() *after* ActOnFinishCXXMemberDecls(), which was trying to define the dllexport method. Now we delay it to ActOnFinishCXXNonNestedClass() which is called after both of those.) Differential revision: https://reviews.llvm.org/D65511 llvm-svn: 367520

* [RISCV] Support 'f' Inline Assembly ConstraintSam Elliott2019-07-311-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Summary: This adds the 'f' inline assembly constraint, as supported by GCC. An 'f'-constrained operand is passed in a floating point register. Exactly which kind of floating-point register (32-bit or 64-bit) is decided based on the operand type and the available standard extensions (-f and -d, respectively). This patch adds support in both the clang frontend, and LLVM itself.

* [Fix] Customize warnings for missing built-in typesJohannes Doerfert2019-07-311-3/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we detect a built-in declaration for which we cannot derive a type matching the pattern in the Builtins.def file, we currently emit a warning that the respective header is needed. However, this is not necessarily the behavior we want as it has no connection to the location of the declaration (which can actually be in the header in question). Instead, this warning is generated - if we could not build the type for the pattern on file (for some reason). Here we should make the reason explicit. The actual problem is otherwise circumvented as the warning is misleading, see [0] for an example. - if we could not build the type for the pattern because we do not have a type on record, possible since D55483, we should not emit any warning. See [1] for a legitimate problem. This patch address both cases. For the "setjmp" family a new warning is introduced and for built-ins without type on record, so far "pthread_create", we do not emit the warning anymore.

This patch resolves this inconsistency by following the gcc lead, which allows make check-all to finish successfully. There's one caveat: gcc defines _LARGEFILE_SOURCE and _LARGEFILE64_SOURCE for C++ only, while clang has long been doing it for all languages. I'd like to keep it this way because those macros do is to make declarations of fseek/ftello (_LARGEFILE_SOURCE) resp. the 64-bit versions of largefile functions (*64 with _LARGEFILE64_SOURCE) visible additionally. However, _FILE_OFFSET_BITS=64 changes all affected functions to be largefile-aware. I'd like to restrict this to C++, just like gcc does. To avoid a similar inconsistence with host compilers that don't predefine _FILE_OFFSET_BITS=64 (e.g. clang < 9, gcc < 9), this needs a compantion patch https://reviews.llvm.org/D64483.

| | | | | | | | | | | | | | | | | | | | | While we implemented taint propagation rules for several builtin/standard functions, there's a natural desire for users to add such rules to custom functions. A series of patches will implement an option that allows users to annotate their functions with taint propagation rules through a YAML file. This one adds parsing of the configuration file, which may be specified in the commands line with the analyzer config: alpha.security.taint.TaintPropagation:Config. The configuration may contain propagation rules, filter functions (remove taint) and sink functions (give a warning if it gets a tainted value). I also added a new header for future checkers to conveniently read YAML files as checker options. Differential Revision: https://reviews.llvm.org/D59555 llvm-svn: 367190

| | | | | | | | | | | | | | | | | | | | | | This is like r305666 (which added support for `if constexpr`) except that it allows a macro name after the if. This is slightly tricky for two reasons: 1. r305666 didn't add test coverage for all cases where it added a kw_constexpr, so I had to figure out what all the added cases were for. I now added tests for all `if constexpr` bits that didn't have tests. (This took a while, see e.g. https://reviews.llvm.org/D65223) 2. Parsing `if <ident> (` as an if means that `#if defined(` and `#if __has_include(` parse as ifs too. Add some special-case code to prevent this from happening where it's incorrect. Fixes PR39248.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A placeholder instruction for use in generation of cleanup code for an initializer list would not be emitted if the base class contained a non-trivial destructor and the class contains no fields of its own. This would be the case when using CTAD to deduce the template arguments for a struct with an overloaded call operator, e.g. ``` template <class... Ts> struct ctad : Ts... {}; template <class... Ts> ctad(Ts...)->ctad<Ts...>; ``` and this class was initialized with a list of lambdas capturing by copy, e.g. ``` ctad c {[s](short){}, [s](long){}}; ``` In a release build the bug would manifest itself as a crash in the SROA pass, however, in a debug build the following assert in CGCleanup.cpp would fail: ``` assert(dominatingIP && "no existing variable and no dominating IP!"); ``` By ensuring that a placeholder instruction is emitted even if there's no fields in the class, neither the assert nor the crash is reproducible.

| | | | | | | | | | | | | As passed in the Cologne meeting and treated by Core as a DR, [[nodiscard]] was applied to constructors so that they can be diagnosed in cases where the user forgets a variable name for a type. The intent is to enable the library to start using this on the constructors of scope_guard/lock_guard. Differential Revision: https://reviews.llvm.org/D64914 llvm-svn: 367027

* [OpenCL] Rename lang mode flag for C++ modeAnastasia Stulova2019-07-251-1/+1
| | | | | | | | | | | | Rename lang mode flag to -cl-std=clc++/-cl-std=CLC++ or -std=clc++/-std=CLC++. This aligns with OpenCL C conversion and removes ambiguity with OpenCL C++. Differential Revision: https://reviews.llvm.org/D65102 llvm-svn: 367008
