* [CodeComplete] Report location of opening parens for signature helpIlya Biryukov2018-08-3011-39/+91

* AMDGPU: Default to hidden visibilityMatt Arsenault2018-08-303-0/+24
| | | | | | | | | | | | Object linking isn't supported, so it's not useful to emit default visibility. Default visibility requires relocations we don't yet support for functions compiled in another translation unit. WebAssembly already does this, although they insert these arguments in a different place for some reason. llvm-svn: 341033
* Ensure canonical type is actually canonical.Richard Trieu2018-08-302-2/+76
| | | | | | | | | ASTContext::applyObjCProtocolQualifiers will return a canonical type when given a canonical type and an array of canonical protocols. If the protocols are not canonical then the returned type is also not canonical. Since a canonical type is needed, canonicalize the returned type before using it. This later prevents a type from having a non-canonical canonical type. llvm-svn: 341013
* Adjust Attr representation so that changes to documentation don't affectRichard Smith2018-08-302-17/+144
| | | | | | | | | | | | | | | | | how we parse source code. Instead of implicitly opting all undocumented attributes out of '#pragma clang attribute' support, explicitly opt them all out and remove the documentation check from TableGen. (No new attributes should be added without documentation, so this has little chance of backsliding. We already support the pragma on one undocumented attribute, so we don't even want to enforce our old "rule".) No functionality change intended. llvm-svn: 341009

* [analyzer] Support modeling no-op BaseToDerived casts in ExprEngine.Artem Dergachev2018-08-296-13/+151
| | | | | | | | | | | | | | | Introduce a new MemRegion sub-class, CXXDerivedObjectRegion, which is the opposite of CXXBaseObjectRegion, to represent such casts. Such region is a bit weird because it is by design bigger than its super-region. But it's not harmful when it is put on top of a SymbolicRegion that has unknown extent anyway. Offset computation for CXXDerivedObjectRegion and proper modeling of casts still remains to be implemented. Differential Revision: https://reviews.llvm.org/D51191 llvm-svn: 340984

This patch allows libFuzzer targets to be built and run on Windows, using -fsanitize=fuzzer and/or fsanitize=fuzzer-no-link. It allows these forms of coverage instrumentation to work on Windows as well. It does not fix all issues, such as those with -fsanitize-coverage=stack-depth, which is not usable on Windows as of this patch. It also does not fix any libFuzzer integration tests. Nearly all of them fail to compile, fixing them will come in a later patch, so libFuzzer tests are disabled on Windows until them.

* [Tooling] Do not restore working dir in ClangToolIlya Biryukov2018-08-292-19/+26
| | | | | | | | | | | | | | | | | | | | | | | Summary: Resolve all relative paths before running the tool instead. This fixes the usage of ClangTool in AllTUsExecutor. The executor will try running multiple ClangTool instances in parallel with compile commands that usually have the same working directory. Changing working directory is a global operation, so we end up changing working directory in the middle of running other actions, which leads to spurious compile errors.

| | | | | | | | | | | | | | ARM_FEATURE_DSP is already set for targets with the +dsp feature. In the backend, this target feature is also used to represent the availability of the of the instructions that the ACLE guard through the __ARM_FEATURE_SIMD32 macro. We don't have any cores that implement one and not the other, so set this macro for cores later than V6 or for Cortex-M cores that the target parser, or user, reports that the 'dsp' instructions are supported.

* [HIP] Fix output file extensionYaxun Liu2018-08-282-1/+10
| | | | | | | | | | | | | | | | | | OffloadBundlingJobAction constructor accepts a list of JobAction as inputs. The host JobAction is the last one. The file type of OffloadBundlingJobAction should be determined by the host JobAction (the last one) instead of the first one. Since HIP emits LLVM bitcode for device compilation, device JobAction has different file type as host Job Action. This bug causes incorrect output file extension for HIP. This patch fixes it by using the last input JobAction (host JobAction) to determine file type of OffloadBundlingJobAction. Differential Revision: https://reviews.llvm.org/D51336 llvm-svn: 340873

| | | | | | | | | | | | | | | Currently an address_space is stored in a qualifier. This makes any type declared with an address_space attribute in the form `__attribute__((address_space(1))) int 1;` be wrapped in an AttributedType. This is for a later patch where if `address_space` is declared in a macro, any diagnostics that would normally print the address space will instead dump the macro name.
