2017-07-08CodeGen: Fix address space of global variableYaxun Liu
Certain targets (e.g. amdgcn) require global variable to stay in global or constant address space. In C or C++ global variables are emitted in the default (generic) address space. This patch introduces virtual functions TargetCodeGenInfo::getGlobalVarAddressSpace and TargetInfo::getConstantAddressSpace to handle this in a general approach. It only affects IR generated for amdgcn target.

2017-07-07[modules ts] Basic for module linkage.Richard Smith
In addition to the formal linkage rules, the Modules TS includes cases where internal-linkage symbols within a module interface unit can be referenced from outside the module via exported inline functions / templates. We give such declarations "module-internal linkage", which is formally internal linkage, but results in an externally-visible symbol. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@307434 91177308-0d34-0410-b5e6-96231b3b80d8

2017-07-06Allow CompilerInvocations to generate .d files.Sterling Augustine
Summary: Most clang tools should ignore the -M family of options because one wouldn't want them to generate a new dependency (.d) file. However, some tools may want this dependency file. This patch creates a mechanism for them to do this. This implementation just plumbs a boolean down several layers of calls. Each of the modified calls has several call sites, and so a single member variable or new API entry point won't work. An alternative would be to write a function to filter the -M family of arguments out of CC1Args, and have each caller call that function by hand before calling newInvocation, Invocation::run, or buildAstFromCodeWithArgs. This is a more complicated and error-prone solution. Why burden all the callers to remember to use this function? But I could rewrite this patch to use that method if that is deemed more appropriate.

2017-07-06[OpenMP] Extend CLANG target options with device offloading kind.Gheorghe-Teodor Bercea
Summary: Pass the type of the device offloading when building the tool chain for a particular target architecture. This is required when supporting multiple tool chains that target a single device type. In our particular use case, the OpenMP and CUDA tool chains will use the same ```addClangTargetOptions ``` method. This enables the reuse of common options and ensures control over options only supported by a particular tool chain.

Summary: Depends on https://reviews.llvm.org/D34867. Add a Clang frontend option to enable optimization remark hotness thresholds, which were added to LLVM in https://reviews.llvm.org/D34867. This prevents diagnostics that do not meet a minimum hotness threshold from being output. When generating optimization remarks for large codebases with a ton of cold code paths, this option can be used to limit the optimization remark output at a reasonable size.

Summary: This patch introduces a few extra BraceWrapping options, similar to `SplitEmptyFunction`, to allow merging empty 'record' bodies (e.g. class, struct, union and namespace): * SplitEmptyClass * SplitEmptyStruct * SplitEmptyUnion * SplitEmptyNamespace The `SplitEmptyFunction` option name has also been simplified/ shortened (from `SplitEmptyFunctionBody`). These options are helpful when the correspond AfterXXX option is enabled, to allow merging the empty record: class Foo {}; In addition, this fixes an unexpected merging of short records, when the AfterXXXX options are used, which caused to be formatted like this: class Foo { void Foo(); }; This is now properly formatted as: class Foo { void Foo(); }; Reviewers: djasper, krasimir Reviewed By: djasper Subscribers: cfe-commits, klimek Differential Revision: https://reviews.llvm.org/D34395 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@306874 91177308-0d34-0410-b5e6-96231b3b80d8

2017-06-28[ASTReader] Treat multiple defns of ObjC protocols the same as interfaces.Graydon Hoare
Summary: In change 2ba19793512, the ASTReader logic for ObjC interfaces was modified to preserve the first definition-data read, "merging" later definitions into it rather than overwriting it (though this "merging" is, in practice, a no-op that discards the later definition-data). Unfortunately this change was only made to ObjC interfaces, not protocols; this means that when (for example) loading a protocol that references an interface, if both the protocol and interface are multiply defined (as can easily happen if the same header is read from multiple contexts), an _inconsistent_ pair of definitions is loaded: first-read for the interface and last-read for the protocol. This in turn causes very subtle downstream bugs in the Swift ClangImporter, which filters the results of name lookups based on the owning module of a definition; inconsistency between a pair of related definitions causes name lookup failures at various stages of compilation. To fix these downstream issues, this change replicates the logic applied to interfaces in change 2ba19793512, but for ObjC protocols. rdar://30851899 Reviewers: doug.gregor, rsmith Reviewed By: doug.gregor Subscribers: jordan_rose, cfe-commits Differential Revision: https://reviews.llvm.org/D34741 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@306583 91177308-0d34-0410-b5e6-96231b3b80d8
