* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* Add two new pragmas for controlling software pipelining optimizations.Aaron Ballman2019-01-041-12/+24
| | | | | | | | This patch adds #pragma clang loop pipeline and #pragma clang loop pipeline_initiation_interval for debugging or reducing compile time purposes. It is possible to disable SWP for concrete loops to save compilation time or to find bugs by not doing SWP to certain loops. It is possible to set value of initiation interval to concrete number to save compilation time by not doing extra pipeliner passes or to check created schedule for specific initiation interval. Patch by Alexey Lapshin. llvm-svn: 350414
* Add support for namespaces on #pragma clang attributeErik Pilkington2018-12-201-6/+40
| | | | | | | | | | | | | | | | Namespaces are introduced by adding an "identifier." before a push/pop directive. Pop directives with namespaces can only pop a attribute group that was pushed with the same namespace. Push and pop directives that don't opt into namespaces have the same semantics. This is necessary to prevent a pitfall of using multiple #pragma clang attribute directives spread out in a large file, particularly when macros are involved. It isn't easy to see which pop corripsonds to which push, so its easy to inadvertently pop the wrong group. Differential revision: https://reviews.llvm.org/D55628 llvm-svn: 349845

* Support for groups of attributes in #pragma clang attributeErik Pilkington2018-10-291-18/+40
| | | | | | | | | | | | | | | | | | This commit enables pushing an empty #pragma clang attribute push, then adding multiple attributes to it, then popping them all with #pragma clang attribute pop, just like #pragma clang diagnostic. We still support the current way of adding these, #pragma clang attribute push(__attribute__((...))), by treating it like a combined push/attribute. This is needed to create macros like: DO_SOMETHING_BEGIN(attr1, attr2, attr3) // ... DO_SOMETHING_END rdar://45496947 Differential revision: https://reviews.llvm.org/D53621 llvm-svn: 345486

* [UnrollAndJam] Add unroll_and_jam pragma handlingDavid Green2018-08-011-13/+40
| | | | | | | | | | | | | | This adds support for the unroll_and_jam pragma, to go with the recently added unroll and jam pass. The name of the pragma is the same as is used in the Intel compiler, and most of the code works the same as for unroll. #pragma clang loop unroll_and_jam has been separated into a different patch. This part adds #pragma unroll_and_jam with an optional count, and #pragma no_unroll_and_jam to disable the transform. Differential Revision: https://reviews.llvm.org/D47267 llvm-svn: 338566

* AttributeList de-listifying:Erich Keane2018-07-121-6/+6
| | | | | | | | | | | Basically, "AttributeList" loses all list-like mechanisms, ParsedAttributes is switched to use a TinyPtrVector (and a ParsedAttributesView is created to have a non-allocating attributes list). DeclaratorChunk gets the later kind, Declarator/DeclSpec keep ParsedAttributes. Iterators are added to the ParsedAttribute types so that for-loops work. llvm-svn: 336945

| | | | | | | | | | | | | This adds the frontend support required to support the use of the comment pragma to enable auto linking on ELFish targets. This is a generic ELF extension supported by LLVM. We need to change the handling for the "dependentlib" in order to accommodate the previously discussed encoding for the dependent library descriptor. Without the custom handling of the PCK_Lib directive, the -l prefixed option would be encoded into the resulting object (which is treated as a frontend error). llvm-svn: 324438

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | '#pragma pack (pop)' and suspicious uses of '#pragma pack' in included files The second recommit (r309106) was reverted because the "non-default #pragma pack value chages the alignment of struct or union members in the included file" warning proved to be too aggressive for external projects like Chromium (https://bugs.chromium.org/p/chromium/issues/detail?id=749197). This recommit makes the problematic warning a non-default one, and gives it the -Wpragma-pack-suspicious-include warning option. The first recommit (r308441) caused a "non-default #pragma pack value might change the alignment of struct or union members in the included file" warning in LLVM itself. This recommit tweaks the added warning to avoid warnings for #includes that don't have any records that are affected by the non-default alignment. This tweak avoids the previously emitted warning in LLVM. Original message: This commit adds a new -Wpragma-pack warning. It warns in the following cases: - When a translation unit is missing terminating #pragma pack (pop) directives. - When entering an included file if the current alignment value as determined by '#pragma pack' directives is different from the default alignment value. - When leaving an included file that changed the state of the current alignment value. rdar://10184173 Differential Revision: https://reviews.llvm.org/D35484 llvm-svn: 309386

* Add #pragma clang fpAdam Nemet2017-04-041-1/+150
| | | | | | | | | | | | | | | | | | | | | | | | | This adds the new pragma and the first variant, contract(on/off/fast). The pragma has the same block scope rules as STDC FP_CONTRACT, i.e. it can be placed at the beginning of a compound statement or at file scope. Similarly to STDC FP_CONTRACT there is no need to use attributes. First an annotate token is inserted with the parsed details of the pragma. Then the annotate token is parsed in the proper contexts and the Sema is updated with the corresponding FPOptions using the shared ActOn function with STDC FP_CONTRACT. After this the FPOptions from the Sema is propagated into the AST expression nodes. There is no change here. I was going to add a 'default' option besides 'on/off/fast' similar to STDC FP_CONTRACT but then decided against it. I think that we'd have to make option uppercase then to avoid using 'default' the keyword. Also because of the scoped activation of pragma I am not sure there is really a need a for this.

* Add loop pragma for Loop DistributionAdam Nemet2016-06-141-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is similar to other loop pragmas like 'vectorize'. Currently it only has state values: distribute(enable) and distribute(disable). When one of these is specified the corresponding loop metadata is generated: !{!"llvm.loop.distribute.enable", i1 true/false} As a result, loop distribution will be attempted on the loop even if Loop Distribution in not enabled globally. Analogously, with 'disable' distribution can be turned off for an individual loop even when the pass is otherwise enabled. There are some slight differences compared to the existing loop pragmas. 1. There is no 'assume_safety' variant which makes its handling slightly different from 'vectorize'/'interleave'. 2. Unlike the existing loop pragmas, it does not have a corresponding numeric pragma like 'vectorize' -> 'vectorize_width'. So for the consistency checks in CheckForIncompatibleAttributes we don't need to check it against other pragmas. We just need to check for duplicates of the same pragma.
