* Objective-C properties: fix bogus use of "isa<>" on a QualType.Douglas Gregor2015-12-081-6/+5
| | | | | | | | | The code used "isa" to check the type and then "getAs" to look through sugar; we need to look through the sugar when checking, too, otherwise any kind of sugar (nullability qualifiers in the example; or a typedef) will thwart this semantic check.

* Module file extensions: pass a Sema through to the extension writer.Douglas Gregor2015-12-083-4/+7

* [Sema] Add warning when comparing nonnull and nullGeorge Burgess IV2015-12-081-28/+45
| | | | | | | | | | | | | | | | | | Currently, we emit warnings in some cases where nonnull function parameters are compared against null. This patch extends this support to warn when comparing the result of `returns_nonnull` functions against null. More specifically, we will now warn cases like: int *foo() __attribute__((returns_nonnull)); int main() { if (foo() == NULL) {} // warning: will always evaluate to false } Differential Revision: http://reviews.llvm.org/D15324 llvm-svn: 255058

* [diagnostics] Avoid crashes while printing macro backtracesReid Kleckner2015-12-081-19/+64
| | | | | | | | | | | | | | | | | | | When attempting to map a source into a given level of macro expansion, this code was ignoring the possibility that the start and end of the range might take wildly different paths through the tree of macro expansions. It was assuming that the begin spelling location would always precede the end spelling location, which is false. A macro can easily transpose its arguments. This also fixes a related issue where there are extra macro arguments between the begin location and the end location. In this situation, we now highlight the entire macro invocation. Pair programmed with Richard Smith. Fixes PR12818. llvm-svn: 254981

* [analyzer] Fix crash when lambda captures a variable-length array.Devin Coughlin2015-12-071-3/+17
| | | | | | | | | | | | When a C++ lambda captures a variable-length array, it creates a capture field to store the size of the array. The initialization expression for this capture is null, which led the analyzer to crash when initializing the field. To avoid this, use the size expression from the VLA type to determine the initialization value. rdar://problem/23748072 llvm-svn: 254962

* [ThinLTO] Option to invoke ThinLTO backend passes and importingTeresa Johnson2015-12-075-53/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Adds new option -fthinlto-index=<file> to invoke the LTO pipeline along with function importing via clang using the supplied function summary index file. This supports invoking the parallel ThinLTO backend processes in a distributed build environment via clang. Additionally, this causes the module linker to be invoked on the bitcode file being compiled to perform any necessary promotion and renaming of locals that are exported via the function summary index file. Add a couple tests that confirm we get expected errors when we try to use the new option on a file that isn't bitcode, or specify an invalid index file. The tests also confirm that we trigger the expected function import pass.

* Fix PR20334: invalid assertion while diagnosing list initialization failureFaisal Vali2015-12-071-1/+3
| | | | | | | | | | | | | https://llvm.org/bugs/show_bug.cgi?id=20334 Unfortunately, clang currently checks for a certain brokenness of implementations of std::initializer_list in CodeGen (void AggExprEmitter::VisitCXXStdInitializerListExpr), not in SemaInit. Until that is fixed, make sure we don't let broken attempts that are aggregates leak through into sema, which allows maintenance of expected invariants, and avoids triggering an assertion. llvm-svn: 254889
* [PGO] Instrument only base constructors and destructors.Serge Pavlov2015-12-067-24/+18
| | | | | | | | | | | | | | | | Constructors and destructors may be represented by several functions in IR. Only base structors correspond to source code, others are small pieces of code and eventually call the base variant. In this case instrumentation of non-base structors has little sense, this fix remove it. Now profile data of a declaration corresponds to exactly one function in IR, it agrees with the current logic of the profile data loading. This change fixes PR24996.

* Fix debug info for Objective-C properties from class extensions after r251874Nico Weber2015-12-041-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After r251874, properties from class extensions no longer show up in ObjCInterfaceDecl::properties(). Make debug info emission explicitly look for properties in class extensions before looking at direct properties. Also add a test that checks for this. There are three interesting cases: 1. A property is only declared in a class extension, and the @implementation is in a different file. This used to generated a DIObjcProperty before r251874 and does again with this fix. 2. A property is declared as readonly in the class itself and redeclared as readwrite in a class extension. clang before r251874 put the DIObjcProperty on the first declaration. clang after r251874 didn't emit any DIObjcProperty, and clang with this fix puts it on the readwrite redeclaration (which is what lookup finds). This seems like a progression. 3. Like 2, but with an @implementation in the same file. In this case, the property debug info gets generated a second time through the ivar from the definition. In this case, lookup and declaration code need to agree on the line number so that the DIObjcProperty isn't emitted twice. In this case, clang before r251874 emitted one DIObjcProperty on the first declaration, clang with r251874 emitted one on the second declaration, and clang with this patch still does the latter. llvm-svn: 254750

* [analyzer] Support inlining lambda-converted blocks.Devin Coughlin2015-12-043-7/+45
| | | | | | | | | clang converts C++ lambdas to blocks with an implicit user-defined conversion operator method on the lambda record. This method returns a block that captures a copy of the lambda. To inline a lambda-converted block, the analyzer now calls the lambda records's call operator method on the lambda captured by the block. llvm-svn: 254702

* LLDB JIT needs android vector passing rules.Stephen Hines2015-12-041-9/+26
| | | | | | | | | | | | | | | | Summary: Looking into some recent issues with LLDBs expression parser highlighted that upstream clang passes vectors types differently to Android Open Source Project's clang for Arm Android targets. This patch reflects the changes present in the AOSP and allows LLDB's JIT expression evaluation to work correctly for Arm Android targets when passing vectors.

* [analyzer] Suppress stack address escape on CK_CopyAndAutoreleaseBlockObject.Devin Coughlin2015-12-031-0/+9
| | | | | | | | | | Don't warn about addresses of stack-allocated blocks escaping if the block region was cast with CK_CopyAndAutoreleaseBlockObject. These casts, which are introduced in the implicit conversion operator for lambda-to-block conversions, cause the block to be copied to the heap -- so the warning is spurious. llvm-svn: 254639
