* [MS ABI] Tolerate invokes of __RTDynamicCastDavid Majnemer2015-11-231-0/+1
| | | | | | | | | | | | The pointer returned by __RTDynamicCast must be bitcasted. However, it was not expected that __RTDynamicCast would be invoked, resulting in the bitcast occuring in a different BasicBlock than the invoke. This caused a down-stream PHI to get confused about which BasicBlock the incomming value was from. This fixes PR25606. llvm-svn: 253843

* Driver: Specifically tell the linker the target for mingw-w64Martell Malone2015-11-221-1/+8
| | | | | | | | | Cross compiling from linux and OSX results in Error: Exec format. This is because the linker is expecting ELF formated objects. By passing the target we can explicitly tell the linker that it should be linking COFF objects regardless of the host. llvm-svn: 253813

* Driver: Defer computation of linker path until it is needed.Peter Collingbourne2015-11-204-14/+7
| | | | | | | This allows us to construct Linux toolchains without a valid linker. This is needed for example to build a CUDA device toolchain after r253385. llvm-svn: 253707
* Thread Safety Analysis: Fix DenseMap iterator invalidation UAFReid Kleckner2015-11-201-39/+36
| | | | | | | | | | | Rather than storing BeforeInfo in the DenseMap by value, this stores a unique_ptr to it, so that we can keep a pointer to it live across subsequent DenseMap insertions. This change also removes the unique_ptr wrapper around BeforeVect because now we're indirecting at a higher level. llvm-svn: 253694

| | | | | | | | | Denis Zobnin. This patch adds support of #pragma vtordisp inside functions in attempt to improve compatibility.

* [analyzer] DeadStoresChecker: Treat locals captured by reference in C++ ↵Devin Coughlin2015-11-201-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | lambdas as escaped. The analyzer currently reports dead store false positives when a local variable is captured by reference in a C++ lambda. For example: int local = 0; auto lambda = [&local]() { local++; }; local = 7; // False Positive: Value stored to 'local' is never read lambda(); In this case, the assignment setting `local` to 7 is not a dead store because the called lambda will later read that assigned value. This commit silences this source of false positives by treating locals captured by reference in C++ lambdas as escaped, similarly to how the DeadStoresChecker deals with locals whose address is taken. rdar://problem/22165179 llvm-svn: 253630

* Change the expression evaluation context from Unevaluated to ↵Faisal Vali2015-11-192-3/+4
| | | | | | | | | | | | ConstantEvaluated while substituting into non-type template argument defaults. Also address a typo from a prior patch that performed a similar fix during Parsing of default non-type template arguments. I left the RAII ExpressionEvaluationContext variable Name as Unevaluated though we had switched the context to ConstantEvaluated. There should be no functionality change here - since when expression evaluation context is popped off, for the most part these two contexts currently behave similarly in regards to lambda diagnostics and odr-use tracking. Like its parsing counterpart, this patch presages the advent of constexpr lambda patches... llvm-svn: 253590

* Don't actually add the __unsafe_unretained qualifier in MRC;John McCall2015-11-194-3/+57
| | | | | | | | | | | driving a canonical difference between that and an unqualified type is a really bad idea when both are valid. Instead, remember that it was there in a non-canonical way, then look for that in the one place we really care about it: block captures. The net effect closely resembles the behavior of a decl attribute, except still closely following ARC's standard qualifier parsing rules. llvm-svn: 253534
* Fix the emission of ARC-style ivar layouts in the fragile runtimeJohn McCall2015-11-191-5/+4
| | | | | | | | | to start at the offset of the first ivar instead of the rounded-up end of the superclass. The latter could include a large amount of tail padding because of a highly-aligned ivar, and subclass ivars can be laid out within that. llvm-svn: 253533
* [analyzer] Improve modeling of static initializers.Anna Zaks2015-11-191-4/+10
| | | | | | | | | | | | Conversions between unrelated pointer types (e.g. char * and void *) involve bitcasts which were not properly modeled in case of static initializers. The patch fixes this problem. The problem was originally spotted by Artem Dergachev. Patched by Yuri Gribov! Differential Revision: http://reviews.llvm.org/D14652 llvm-svn: 253532
* [MS ABI] Let arbitrary entities participate in vftable orderingDavid Majnemer2015-11-191-6/+10
| | | | | | | | | | | In the Microsoft ABI, the vftable is laid out in the order in the declaration order of the entities defined within it. Obviously, only virtual methods end up in the vftable but they will be placed into the table at the same position as the first entity with the same name. llvm-svn: 253523
* Fix debian build after r253512.Pete Cooper2015-11-181-3/+4
| | | | | | | | | | | The conversion from QuantityType to the (temporary) IntegerAlignment class was ambiguous. For now add in explicit conversion to unsigned to satisfy the clang-x86_64-debian-fast bot. I'll remove the explicit conversion when I remove the IntegerAlignment class. llvm-svn: 253519
* [analyzer] Skip checking blocks in dependent contexts.Devin Coughlin2015-11-181-1/+5
| | | | | | | | | | | Since we don't check functions in dependent contexts, we should skip blocks in those contexts as well. This avoids an assertion failure when the DeadStoresChecker attempts to evaluate an array subscript expression with a dependent name type. rdar://problem/23564220 llvm-svn: 253516
* Change memcpy/memset/memmove to have dest and source alignments.Pete Cooper2015-11-181-6/+6
| | | | | | | | | | | | | | | | | | | | | | This is a follow on from a similar LLVM commit: r253511. Note, this was reviewed (and more details are in) http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20151109/312083.html These intrinsics currently have an explicit alignment argument which is required to be a constant integer. It represents the alignment of the source and dest, and so must be the minimum of those. This change allows source and dest to each have their own alignments by using the alignment attribute on their arguments. The alignment argument itself is removed. The only code change to clang is hidden in CGBuilder.h which now passes both dest and source alignment to IRBuilder, instead of taking the minimum of dest and source alignments.

* [Sema] Don't work around a malformed ASTDavid Majnemer2015-11-182-3/+11
| | | | | | | | | | | | We created a malformed TemplateSpecializationType: it was dependent but had a RecordType as it's canonical type. This would lead getAs to crash. r249090 worked around this but we should fix this for real by providing a more appropriate template specialization type as the canonical type. This fixes PR24246. llvm-svn: 253495
