* utils: Silence -Wpedantic warningSaleem Abdulrasool2017-05-011-2/+2

* Add #pragma clang attribute support to the external_source_symbol attributeAlex Lorenz2017-04-191-24/+113
| | | | | | | | | | | | | | | | | | | Prior to this commit the external_source_symbol attribute wasn't supported by #pragma clang attribute for the following two reasons: - The Named attribute subject hasn't been supported by TableGen. - There was no way to specify a subject match rule for #pragma clang attribute that could operate on a set of attribute subjects (e.g. the ones that derive from NamedDecl). This commit fixes the two issues and thus adds external_source_symbol support to #pragma clang attribute. rdar://31169028 Differential Revision: https://reviews.llvm.org/D32176 llvm-svn: 300712
* Add #pragma clang attributeAlex Lorenz2017-04-183-12/+470
| | | | | | | | | | | | | | | | | This is a recommit of r300539 that was reverted in r300543 due to test failures. The original commit message is displayed below: The new '#pragma clang attribute' directive can be used to apply attributes to multiple declarations. An attribute must satisfy the following conditions to be supported by the pragma: - It must have a subject list that's defined in the TableGen file. - It must be documented. - It must not be late parsed. - It must have a GNU/C++11 spelling.

* [NFC, Scoped Enum] Convert Sema::ExpressionEvaluationContext into a scoped EnumFaisal Vali2017-04-011-2/+2
| | | | | | | | - also replace direct equality checks against the ConstantEvaluated enumerator with isConstantEvaluted(), in anticipation of adding finer granularity to the various ConstantEvaluated contexts and reinstating certain restrictions on where lambda expressions can occur in C++17. - update the clang tablegen backend that uses these Enumerators, and add the relevant scope where needed. llvm-svn: 299316
* Correct class-template deprecation behavior-REDUXErich Keane2017-03-231-16/+28
| | | | | | | | | | | | | | | | | | Correct class-template deprecation behavior Based on the comment in the test, and my reading of the standard, a deprecated warning should be issued in the following case: template<typename T> [[deprecated]] class Foo{}; Foo<int> f; This was not the case, because the ClassTemplateSpecializationDecl creation did not also copy the deprecated attribute. Note: I did NOT audit the complete set of attributes to see WHICH ones should be copied, so instead I simply copy ONLY the deprecated attribute. Previous DiffRev: https://reviews.llvm.org/D27486, was reverted.

* Switch TableGen to emit calls to ASTRecordReader for AttrPCHRead.David L. Jones2017-01-241-19/+19
| | | | | | | | | | | | | | | Summary: This patch changes TableGen-generated code in AttrPCHRead to call functions on ASTRecordReader, instead of passing separate parameters to ASTReader.

* [TableGen] Only normalize the spelling of GNU-style attributes.Justin Lebar2017-01-051-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When Sema looks up an attribute name, it strips off leading and trailing "__" if the attribute is GNU-style. That is, __attribute__((foo)) and __attribute__((__foo__)) are equivalent. This is only true for GNU-style attributes. In particular, __declspec(__foo__) is not equivalent to __declspec(foo), and Sema respects this difference. This patch fixes TableGen to match Sema's behavior. The spelling 'GNU<"__foo__">' should be normalized to 'GNU<"foo">', but 'Declspec<"__foo__">' should not be changed. This is necessary to make CUDA compilation work on Windows, because e.g. the __device__ attribute is spelled __declspec(__device__). Attr.td does not contain any Declspec spellings that start or end with "__", so this change should not affect any other attributes.

In llvm/tools/clang/CMakeLists.txt add_subdirectory(utils/perf-training) should go after the block where the value of the variable CLANG_ORDER_FILE is set - otherwise (tested with cmake's version 3.6.2) the arguments of perf-helper.py gen-order-file will be ill-formed (CLANG_ORDER_FILE will be empty).

* [TableGen] Ignore fake args for parsing-related arg counts.George Burgess IV2016-12-011-0/+4
| | | | | | | | | | | | | | | | | | We should complain about the following: ``` void foo() __attribute__((unavailable("a", "b"))); ``` Instead, we currently just ignore "b". (...We also end up ignoring "a", because we assume elsewhere that this attribute can only have 1 or 0 args.) This happens because `unavailable` has a fake enum arg, and `AttributeList::{getMinArgs,getMaxArgs}` include fake args in their counts. llvm-svn: 288388

Summary: This attribute specifies expectations about the initialization of static and thread local variables. Specifically that the variable has a [constant initializer](http://en.cppreference.com/w/cpp/language/constant_initialization) according to the rules of [basic.start.static]. Failure to meet this expectation will result in an error. Static objects with constant initializers avoid hard-to-find bugs caused by the indeterminate order of dynamic initialization. They can also be safely used by other static constructors across translation units. This attribute acts as a compile time assertion that the requirements for constant initialization have been met. Since these requirements change between dialects and have subtle pitfalls it's important to fail fast instead of silently falling back on dynamic initialization. ```c++ // -std=c++14 #define SAFE_STATIC __attribute__((require_constant_initialization)) static struct T { constexpr T(int) {} ~T(); }; SAFE_STATIC T x = {42}; // OK. SAFE_STATIC T y = 42; // error: variable does not have a constant initializer // copy initialization is not a constant expression on a non-literal type. ``` This attribute can only be applied to objects with static or thread-local storage duration.
