Merge pending instantiations instead of overwriting existing ones. Check whether a pending instantiation needs to be instantiated (or whether an instantiation already exists). Verify the size of the PendingInstantiations record (was only checking size of existing PendingInstantiations). Migrate Obj-C++ part of redecl-merge into separate test, now that this is growing. templates.mm: test that CodeGen has seen exactly one definition of template instantiations. redecl-merge.m: use "@" specifier for expected-diagnostics. llvm-svn: 164993

[modules] Simplify -cc1 interface for enabling implicit module maps. We used to have a flag to enable module maps, and two more flags to enable implicit module maps. This is all redundant; we don't need any flag for enabling module maps in the abstract, and we don't usually have -fno- flags for -cc1. We now have just a single flag, -fimplicit-module-maps, that enables implicitly searching the file system for module map files and loading them. The driver interface is unchanged for now. We should probably rename -fmodule-maps to -fimplicit-module-maps at some point. llvm-svn: 239789

[modules] Don't emit initializers for VarDecls within a module eagerly whenever we first touch any part of that module. Instead, defer them until the first time that module is (transitively) imported. The initializer step for a module then recursively initializes modules that its own headers imported. For example, this avoids running the <iostream> global initializer in programs that don't actually use iostreams, but do use other parts of the standard library. llvm-svn: 276159

When a module completes the definition of a class template specialization imported from another module, emit an update record, rather than using the broken decl rewriting mechanism.

If we see an explicit instantiation declaration or definition of a function after we've already instantiated a definition for the function, pass it to the ASTConsumer again so that it knows the specialization kind has changed and can update the function's linkage. This only matters if we instantiate the definition of the function before we reach the end of the TU; this can happen in at least three different ways: C++11 constexpr functions, C++14 deduced return types, and functions instantiated within modules. llvm-svn: 207152

C++ modules: if a class is defined in multiple modules (for instance, because it is an implicit instantiation of a class template specialization), pick the first-loaded definition to be the canonical definition, and merge all other definitions into it. This is still rather incomplete -- we need to extend every form of declaration that can appear within a CXXRecordDecl to be redeclarable if it came from an AST file (this includes fields, enumerators, ...). llvm-svn: 190315

When merging class definitions across modules in C++, merge together fields.

Mark C++ reference parameters as dereferenceable Because references must be initialized using some evaluated expression, they must point to something, and a callee can assume the reference parameter is dereferenceable. Taking advantage of a new attribute just added to LLVM, mark them as such. Because dereferenceability in addrspace(0) implies nonnull in the backend, we don't need both attributes. However, we need to know the size of the object to use the dereferenceable attribute, so for incomplete types we still emit only nonnull. llvm-svn: 213386

When two templates get merged together, also merge their pattern declarations together. This is extremely hairy, because in general we need to have loaded both the template and the pattern before we can determine whether either should be merged, so we temporarily violate the rule that all merging happens before reading a decl ends, but *only* in the case where a template's pattern is being loaded while loading the template itself. In order to accomodate this for class templates, delay loading the injected class name type for the pattern of the template until after we've loaded the template itself, if we happen to load the template first. llvm-svn: 207063
