* Produce direct calls instead of alias to linkonce_odr functions.Rafael Espindola2013-11-051-18/+23
| | | | | | | This is a small optimization on linux, but should help more on windows where msvc only outputs one destructor if there would be two identical ones. llvm-svn: 194046

* Include non-explicit submodules in exported module listDmitri Gribenko2013-11-042-10/+11
| | | | | | | | | | | | | | | | This change fixes Richard's testcase for r193815. Now we include non-explicit submodules into the list of exports. The test failed previously because: - recursive_visibility_a1.inner is not imported (only recursive_visibility_a1 is), - thus the 'inner' submodule is not showing up in any of the import lists, - and because of this getExportedModules() is not returning the correct module set -- it only considers modules that are imported. The fix is to make Module::getExportedModules() include non-explicit submodules into the list of exports. llvm-svn: 194018
* [analyzer] Track the count of NSOrderedSet similarly to other fast enumerations.Anna Zaks2013-11-041-1/+2

* [analyzer] Suppress warnings coming out of std::basic_string.Anna Zaks2013-11-041-0/+12
| | | | | | The analyzer cannot reason about the internal invariances of the data structure (radar://15194597). llvm-svn: 194004
* Try to correct a mistyped "-" or ">" to "->" for some C++ cases.Kaelyn Uhrain2013-11-041-0/+40
| | | | | | | | | | | | Similar C code isn't caught as it seems to hit a different code path. Also, as the check is only done for record pointers, cases involving an overloaded operator-> are not handled either. Note that the reason this check is done in the parser instead of Sema is not related to having enough knowledge about the current state as it is about being able to fix up the parser's state to be able to recover and traverse the correct code paths. llvm-svn: 194002
* Use aliases for more constructors and destructors.Rafael Espindola2013-11-043-42/+50
| | | | | | | | | | | | | | | | With this patch we produce alias for cases like template<typename T> struct foobar { foobar() { } }; template struct foobar<void>; We just have to be careful to produce the same aliases in every TU because of comdats. llvm-svn: 194000

* CodeGen: Use EmitBranchOnBool when generating For and CXXForRangeJustin Bogner2013-11-041-5/+2
| | | | | | | | | | | | | A while ago EmitForStmt was changed to explicitly evaluate the condition expression and create a branch instead of using EmitBranchOnBool, so that the condition expression could be used for some cleanup logic. The cleanup stuff has since been reorganized, and this is no longer necessary. In EmitCXXForRange, the evaluated condition was never used for anything else. The logic was presumably modeled on EmitForStmt. llvm-svn: 193994
* CodeGen: Move an initialization away from an unrelated commentJustin Bogner2013-11-041-1/+1
| | | | | | | | An initialization somehow found its way in between a comment and the block of code the comment is about. Moving the initialization makes this less confusing. llvm-svn: 193993

Also, don't delete such members if a subobject has no corresponding move operation and a non-trivial copy. This causes us to implicitly declare move operations in more cases, but risks move-assigning virtual bases multiple times in some circumstances (a warning for that is to follow). llvm-svn: 193969
* Sema: Do not allow overloading between methods based on restrictDavid Majnemer2013-11-032-2/+12
| | | | | | | | | | | | | | | | If the sole distinction between two declarations is that one has a __restrict qualifier then we should not consider it to be an overload. Instead, we will consider it as an incompatible redeclaration which is similar to how MSVC, ICC and GCC would handle it. This fixes PR17786. N.B. We must not mangle in __restrict into method qualifiers becase we don't allow overloading between such declarations anymore. To do otherwise would be a violation of the Itanium ABI. llvm-svn: 193964

* Sema: Disallow inheriting from classes with flexible array membersDavid Majnemer2013-11-021-0/+12
| | | | | | | | | | | Flexible array members inherently index off of the end of their parent type. We shouldn't allow this type to be used as a base, virtual or otherwise, because indexing off the end may find us inside of another base or the derived types members. llvm-svn: 193923

* Sema: Disallow derived classes with virtual bases from having flexible array ↵David Majnemer2013-11-021-0/+9
| | | | | | | | | | | | | | | members Flexible array members only work out if they are the last field of a record, however virtual bases would give us many situations where the flexible array member would overlap with the virtual base fields. It is unlikely in the extreme that this behavior was intended by the user so raise a diagnostic instead of accepting. This is will not reject conforming code because flexible array members are an extension in C++ mode. llvm-svn: 193920
* Sema: Cleanup and simplify anonymous union diagnosticsDavid Majnemer2013-11-021-34/+23
| | | | | | | | | | | | | | | | The determination of which diagnostics would be issued for certain anonymous unions started to get a little ridiculous. Clean this up by inverting the condition-tree's logic from dialect -> issue to issue -> diagnostic. As part of this cleanup, move ext_c99_flexible_array_member from DiagnosticParseKinds.td to DiagnosticSemaKinds.td because it's driven by Sema, not Parse. Also, the liberty was taken to edit ext_c99_flexible_array_member to match other, similar, diagnostics. llvm-svn: 193919
* Sema: Flexible array members were introduced in C99, diagnose their use in C++David Majnemer2013-11-021-0/+6
| | | | | | | The declaration of a flexible array member was correctly diagnosed as an extension in C89 mode but not in C++. llvm-svn: 193918

| | | | | | | | | | | | | Differential Revision: http://llvm-reviews.chandlerc.com/D2090 Clang was "improperly" over-aligning arrays with sizes are not a multiple of their alignment. This behavior was removed in microsoft 32 bit mode. In addition, after examination of ASTContext::getTypeInfoImpl, a redundant code block in MicrosoftRecordLayoutBuilder::getAdjustedFieldInfo was deleted. llvm-svn: 193898
* Wraps lazily generated builtins in an extern "C" contextWarren Hunt2013-11-012-26/+31
| | | | | | | | | | | | | Differential Revision: http://llvm-reviews.chandlerc.com/D2082 Adds a lang_c LinkageSpecDecl to lazily generated builtins. This enforces correct behavior for builtins in a variety of cases without special treatment elsewhere within the compiler (special treatment is removed by the patch). It also allows for C++ overloads of builtin functions, which Microsoft uses in their headers e.g. _InterlockedExchangeAdd is an extern C builtin for the long type but an inline wrapper for int type. llvm-svn: 193896

* SanitizerArgs: add ability to filter/diagnose unsupported sanitizers.Peter Collingbourne2013-11-015-59/+121
| | | | | | | | | | | | The thread, memory, dataflow and function sanitizers are now diagnosed if enabled explicitly on an unsupported platform. Unsupported sanitizers which are enabled implicitly (as part of a larger group) are silently disabled. As a side effect, this makes SanitizerArgs parsing toolchain-dependent (and thus essentially reverts r188058), and moves SanitizerArgs ownership to ToolChain.

* Clang modules: collect exports recursivelyDmitri Gribenko2013-10-311-9/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes Module::buildVisibleModulesCache() collect exported modules recursively. While computing a set of exports, getExportedModules() iterates over the set of imported modules and filters it. But it does not consider the set of exports of those modules -- it is the responsibility of the caller to do this. Here is a certain instance of this issue. Module::isModuleVisible says that CoreFoundation.CFArray submodule is not visible from Cocoa. Why? - Cocoa imports Foundation. - Foundation has an export restriction: "export *". - Foundation imports CoreFoundation. (Just the top-level module.) - CoreFoundation exports CoreFoundation.CFArray. To decide which modules are visible from Cocoa, we collect all exported modules from immediate imports in Cocoa: > visibleModulesFro(Cocoa) = exported(Foundation) + exported(CoreData) + exported(AppKit) To find out which modules are exported, we filter imports according to restrictions: > exported(Foundation) = filterByModuleMapRestrictions(imports(Foundation)) Because Foundation imports CoreFoundation (not CoreFoundation.CFArray), the CFArray submodule is considered not exported from Foundation, and is not visible from Cocoa (according to Module::isModuleVisible). llvm-svn: 193815

* Fixed bug with checking the kind of types.Chris Wailes2013-10-311-4/+8
| | | | | | | | | | | | | | The isLValueReferenceType function checks to see if the QualType's canonical type is an LValue reference, and not if the QualType itself is an LValue reference. This caused a segfault when trying to cast the QualType's Type to a LValueReference. This is now fixed by casting the result of getCanonicalType(). In addition, a test was added to isConsumableType to prevent segfaults when a type being tested by the analysis is a reference to a pointer or a pointer to a reference. llvm-svn: 193751

Introduced a "generic" CPU which will ensure that the optional FP feature is enabled by default when it gets to LLVM, without needing any extra arguments. Cortex-A53 and A-57 are also introduced with tests, although backend handling of them does not yet exist. llvm-svn: 193740
