* [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.

* [clang] Fix clean build of generate-order-fileAlexander Shaposhnikov2016-12-311-1/+5
| | | | | | | | | | | | | | This diff fixes the clean build of the target generate-order-file. 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@288388 91177308-0d34-0410-b5e6-96231b3b80d8

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.

| | | | | | | | | | | Improved the visualizer for TemplateArgumentList to show type arguments in the DisplayString. E.g., <double, long>. Added a visualizer for MultiLevelTemplateArgumentList. I decided to display them by how they would appear in a template with the (non-existent) template-id's omitted, so the DisplayString naturally presents as something like <double, long>::<char *>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@271944 91177308-0d34-0410-b5e6-96231b3b80d8
