* [P0936R0] add [[clang::lifetimebound]] attributeRichard Smith2018-08-011-2/+7
| | | | | | | | | | | | | | | | | | | | This patch adds support for a new attribute, [[clang::lifetimebound]], that indicates that the lifetime of a function result is related to one of the function arguments. When walking an initializer to make sure that the lifetime of the initial value is at least as long as the lifetime of the initialized object, we step through parameters (including the implicit object parameter of a non-static member function) that are marked with this attribute. There's nowhere to write an attribute on the implicit object parameter, so in lieu of that, it may be applied to a function type (where it appears immediately after the cv-qualifiers and ref-qualifier, which is as close to a declaration of the implicit object parameter as we have). I'm currently modeling this in the AST as the attribute appertaining to the function type.

* Implement cpu_dispatch/cpu_specific MultiversioningErich Keane2018-07-201-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As documented here: https://software.intel.com/en-us/node/682969 and https://software.intel.com/en-us/node/523346. cpu_dispatch multiversioning is an ICC feature that provides for function multiversioning. This feature is implemented with two attributes: First, cpu_specific, which specifies the individual function versions. Second, cpu_dispatch, which specifies the location of the resolver function and the list of resolvable functions. This is valuable since it provides a mechanism where the resolver's TU can be specified in one location, and the individual implementions each in their own translation units. The goal of this patch is to be source-compatible with ICC, so this implementation diverges from the ICC implementation in a few ways: 1- Linux x86/64 only: This implementation uses ifuncs in order to properly dispatch functions. This is is a valuable performance benefit over the ICC implementation. A future patch will be provided to enable this feature on Windows, but it will obviously more closely fit ICC's implementation. 2- CPU Identification functions: ICC uses a set of custom functions to identify the feature list of the host processor. This patch uses the cpu_supports functionality in order to better align with 'target' multiversioning. 1- cpu_dispatch function def/decl: ICC's cpu_dispatch requires that the function marked cpu_dispatch be an empty definition. This patch supports that as well, however declarations are also permitted, since the linker will solve the issue of multiple emissions.

* Re-apply: Add python tool to dump and construct header mapsBruno Cardoso Lopes2018-06-212-0/+312
| | | | | | | | | | | | | | | | | | | | | | | | | Header maps are binary files used by Xcode, which are used to map header names or paths to other locations. Clang has support for those since its inception, but there's not a lot of header map testing around. Since it's a binary format, testing becomes pretty much brittle and its hard to even know what's inside if you don't have the appropriate tools. Add a python based tool that allows creating and dumping header maps based on a json description of those. While here, rewrite tests to use the tool and remove the binary files from the tree. This tool was initially written by Daniel Dunbar. Thanks to Stella Stamenova for helping make this work on Windows.

* [Clang Tablegen][RFC] Allow Early Textual Substitutions in `Diagnostic` ↵Eric Fiselier2018-05-191-263/+743
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | messages. Summary: There are cases where the same string or select is repeated verbatim in a lot of diagnostics. This can be a pain to maintain and update. Tablegen provides no way stash the common text somewhere and reuse it in the diagnostics, until now! This patch allows diagnostic texts to contain `%sub{<definition-name>}`, where `<definition-name>` names a Tablegen record of type `TextSubstitution`. These substitutions are done early, before the diagnostic string is otherwise processed. All `%sub` modifiers will be replaced before the diagnostic definitions are emitted. The substitution must specify all arguments used by the substitution, and modifier indexes in the substitution are re-numbered accordingly. For example: ``` def select_ovl_candidate : TextSubstitution<"%select{function|constructor}0%select{| template| %2}1">; ``` when used as ``` "candidate `%sub{select_ovl_candidate}3,2,1 not viable" ``` will act as if we wrote: ``` "candidate %select{function|constructor}3%select{| template| %1}2 not viable" ``` Reviewers: rsmith, rjmccall, aaron.ballman, a.sidorin Reviewed By: rjmccall Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D46740 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@332799 91177308-0d34-0410-b5e6-96231b3b80d8

* [Attr] Fix parameter indexing for several attributesJoel E. Denny2018-03-021-3/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch fixes a number of bugs related to parameter indexing in attributes: * Parameter indices in some attributes (argument_with_type_tag, pointer_with_type_tag, nonnull, ownership_takes, ownership_holds, and ownership_returns) are specified in source as one-origin including any C++ implicit this parameter, were stored as zero-origin excluding any this parameter, and were erroneously printing (-ast-print) and confusingly dumping (-ast-dump) as the stored values. * For alloc_size, the C++ implicit this parameter was not subtracted correctly in Sema, leading to assert failures or to silent failures of __builtin_object_size to compute a value. * For argument_with_type_tag, pointer_with_type_tag, and ownership_returns, the C++ implicit this parameter was not added back to parameter indices in some diagnostics. This patch fixes the above bugs and aims to prevent similar bugs in the future by introducing careful mechanisms for handling parameter indices in attributes. ParamIdx stores a parameter index and is designed to hide the stored encoding while providing accessors that require each use (such as printing) to make explicit the encoding that is needed. Attribute declarations declare parameter index arguments as [Variadic]ParamIdxArgument, which are exposed as ParamIdx[*]. This patch rewrites all attribute arguments that are processed by checkFunctionOrMethodParameterIndex in SemaDeclAttr.cpp to be declared as [Variadic]ParamIdxArgument. The only exception is xray_log_args's argument, which is encoded as a count not an index.

* [OpenMP] Fix trailing space when printing pragmas, by Joel. E. DennyAlexey Bataev2018-02-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: -ast-print prints omp pragmas with a trailing space. While this behavior is likely of little concern to most users, surely it's unintentional, and it's annoying for some source-level work I'm pursuing. This patch focuses on omp pragmas, but it also fixes init_seg and loop hint pragmas because they share implementation. The testing strategy here is to add usually just one '{{$}}' per relevant -ast-print test file. This seems to achieve good code coverage. However, this strategy is probably easy to forget as the tests evolve. That's probably fine as this fix is far from critical. The main goal of the testing is to aid the initial review. This patch also adds a fixme for "#pragma unroll", which prints as "#pragma unroll (enable)", which is invalid syntax.
