* [ASTImporter] Import ctor initializers after setting flags.Balazs Keri2019-08-161-0/+11
| | | | | | | | | | | | | | | | | | | | Summary: Code to import "ctor initializers" at import of functions is moved to be after the flags in the newly created function are imported. This fixes an error when the already created but incomplete (flags are not set) function declaration is accessed.

* [ASTImporter] Import default expression of param before creating the param.Balazs Keri2019-08-141-0/+19
| | | | | | | | | | | | | | | | | | | | | Summary: The default expression of a parameter variable should be imported before the parameter variable object is created. Otherwise the function is created with an incomplete parameter variable (default argument is nullptr) and in this intermediary state the expression is imported. This import can have a reference to the incomplete parameter variable that causes crash.

* [CrossTU] Handle case when no USR could be generated during Decl search.Balazs Keri2019-08-061-0/+14
| | | | | | | | | | | | | | | | | | | Summary: When searching for a declaration to be loaded the "lookup name" for every other Decl is computed. If the USR can not be determined here should be not an assert, instead skip this Decl.

* [analyzer][CrossTU] Extend CTU to VarDecls with initializerRafael Stahl2019-04-231-0/+38
| | | | | | | | | | | | | | | | | | | | | | Summary: The existing CTU mechanism imports `FunctionDecl`s where the definition is available in another TU. This patch extends that to VarDecls, to bind more constants. - Add VarDecl importing functionality to CrossTranslationUnitContext - Import Decls while traversing them in AnalysisConsumer - Add VarDecls to CTU external mappings generator - Name changes from "external function map" to "external definition map" Reviewers: NoQ, dcoughlin, xazax.hun, george.karpenkov, martong Reviewed By: xazax.hun Subscribers: Charusso, baloghadamsoftware, mikhail.ramalho, Szelethus, donat.nagy, dkrupp, george.karpenkov, mgorny, whisperity, szepet, rnkovacs, a.sidorin, cfe-commits Tags: #clang Differential Revision: https://reviews.llvm.org/D46421 llvm-svn: 358968
* [ASTImporter] Fix handling of overriden methods during ASTImportShafik Yaghmour2019-01-281-13/+18
| | | | | | | | | Summary: When importing classes we may add a CXXMethodDecl more than once to a CXXRecordDecl when handling overrides. This patch will fix the cases we currently know about and handle the case where we are only dealing with declarations. Differential Revision: https://reviews.llvm.org/D56936 llvm-svn: 352436

* [ASTImporter] Allow testing of import sequences; fix import of typedefs for ↵Aleksei Sidorin2018-04-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | anonymous decls This patch introduces the ability to test an arbitrary sequence of imports between a given set of virtual source files. This should finally allow us to write simple tests and fix annoying issues inside ASTImporter that cause failures in CSA CTU. This is done by refactoring ASTImporterTest functions and introducing `testImportSequence` facility. As a side effect, `testImport` facility was generalized a bit more. It should now allow import of non-decl AST nodes; however, there is still no test using this ability. As a "test for test", there is also a fix for import anonymous TagDecls referred by typedef. Before this patch, the setting of typedef for anonymous structure was delayed; however, this approach misses the corner case if an enum constant is imported directly. In this patch, typedefs for anonymous declarations are imported right after the anonymous declaration is imported, without any delay. Thanks to Adam Balogh for suggestions included into this patch.

* Resubmit [analyzer] Support for naive cross translation unit analysisIlya Biryukov2018-03-011-0/+67
| | | | | | | | | | | Originally submitted as r326323 and r326324. Reverted in r326432. Reverting the commit was a mistake. The breakage was due to invalid build files in our internal buildsystem, CMakeLists did not have any cyclic dependencies. llvm-svn: 326439
* Revert "[analyzer] Support for naive cross translation unit analysis"Ilya Biryukov2018-03-011-67/+0
| | | | | | | | | | Also revert "[analyzer] Fix a compiler warning" This reverts commits r326323 and r326324. Reason: the commits introduced a cyclic dependency in the build graph. This happens to work with cmake, but breaks out internal integrate. llvm-svn: 326432

The aim of this patch is to be minimal to enable incremental development of the feature on the top of the tree. This patch should be an NFC when the feature is turned off. It is turned off by default and still considered as experimental. Technical details are available in the EuroLLVM Talk: http://llvm.org/devmtg/2017-03//2017/02/20/accepted-sessions.html#7 Note that the initial prototype was done by A. Sidorin et al.: http://lists.llvm.org/pipermail/cfe-dev/2015-October/045730.html Contributions to the measurements and the new version of the code: Peter Szecsi, Zoltan Gera, Daniel Krupp, Kareem Khazem.
