* Emit used/dllexport inline method definitions in nested classes (PR19743, ↵Hans Wennborg2014-05-231-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PR11170) The previous code that was supposed to handle this didn't work since parsing of inline method definitions is delayed to the end of the outer class definition. Thus, when HandleTagDeclDefinition() got called for the inner class, the inline functions in that class had not been parsed yet. Richard suggested that the way to do this is by handling inline method definitions through a new ASTConsumer callback. I really wanted to call ASTContext::DeclMustBeEmitted() instead of checking for attributes, but doing that causes us to compute linkage, and then we fail with "error: unsupported: typedef changes linkage of anonymous type, but linkage was already computed" on tests like this: (from SemaCXX/undefined-internal.cpp) :-/ namespace test7 { typedef struct { void bar(); void foo() { bar(); } } A; } Differential Revision: http://reviews.llvm.org/D3809 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@209549 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | Rather than going through the whole getOrCreateType machinery to manifest a type, cut straight to the implementation because we know we have to do work. While the previous implementation was sufficient for the two cases (completeness and required completeness) we have already (the general machinery could inspect the type for those attributes & go down the full definition path), a pending change (to emit info for types when we emit their vtables) won't have that luxury & we'll need to force the creation rather than relying on the general purpose routine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@188486 91177308-0d34-0410-b5e6-96231b3b80d8

* Forward #pragma comment(lib/linker) through as flags metadataReid Kleckner2013-05-081-0/+9
| | | | | | | | | | | | | | | | | | | | | | Summary: Most of this change is wiring the pragma all the way through from the lexer, parser, and sema to codegen. I considered adding a Decl AST node for this, but it seemed too heavyweight. Mach-O already uses a metadata flag called "Linker Options" to do this kind of auto-linking. This change follows that pattern. LLVM knows how to forward the "Linker Options" metadata into the COFF .drectve section where these flags belong. ELF support is not implemented, but possible. This is related to auto-linking, which is http://llvm.org/PR13016.

* Rework when and how vtables are emitted, by tracking where vtables areDouglas Gregor2010-05-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "used" (e.g., we will refer to the vtable in the generated code) and when they are defined (i.e., because we've seen the key function definition). Previously, we were effectively tracking "potential definitions" rather than uses, so we were a bit too eager about emitting vtables for classes without key functions. The new scheme: - For every use of a vtable, Sema calls MarkVTableUsed() to indicate the use. For example, this occurs when calling a virtual member function of the class, defining a constructor of that class type, dynamic_cast'ing from that type to a derived class, casting to/through a virtual base class, etc. - For every definition of a vtable, Sema calls MarkVTableUsed() to indicate the definition. This happens at the end of the translation unit for classes whose key function has been defined (so we can delay computation of the key function; see PR6564), and will also occur with explicit template instantiation definitions. - For every vtable defined/used, we mark all of the virtual member functions of that vtable as defined/used, unless we know that the key function is in another translation unit. This instantiates virtual member functions when needed. - At the end of the translation unit, Sema tells CodeGen (via the ASTConsumer) which vtables must be defined (CodeGen will define them) and which may be used (for which CodeGen will define the vtables lazily). From a language perspective, both the old and the new schemes are permissible: we're allowed to instantiate virtual member functions whenever we want per the standard. However, all other C++ compilers were more lazy than we were, and our eagerness was both a performance issue (we instantiated too much) and a portability problem (we broke Boost test cases, which now pass). Notes: (1) There's a ton of churn in the tests, because the order in which vtables get emitted to IR has changed. I've tried to isolate some of the larger tests from these issues. (2) Some diagnostics related to implicitly-instantiated/implicitly-defined virtual member functions have moved to the point of first use/definition. It's better this way. (3) I could use a review of the places where we MarkVTableUsed, to see if I missed any place where the language effectively requires a vtable.
