When writing a PCH file, keep track of all of the non-static, non-inline external definitions (and tentative definitions) that are found at the top level. The corresponding declarations are stored in a record in the PCH file, so that they can be provided to the ASTConsumer (via HandleTopLevelDecl) when the PCH file is read. llvm-svn: 69005 2009-04-14 08:24:19 +08:00			`// Helper for external-defs.c test`

When building a PCH file, don't perform end-of-translation-unit wrap-up (e.g., turning tentative definitions into definitions). Also, very that, when we actually use the PCH file, we get the ride code generation for tentative definitions and definitions that show up in the PCH file. llvm-svn: 69043 2009-04-15 00:27:31 +08:00			`// Tentative definitions`

Explictly track tentative definitions within Sema, then hand those tentative definitions off to the ASTConsumer at the end of the translation unit. Eliminate CodeGen's internal tracking of tentative definitions, and instead hook into ASTConsumer::CompleteTentativeDefinition. Also, tweak the definition-deferal logic for C++, where there are no tentative definitions. Fixes <rdar://problem/6808352>, and will make it much easier for precompiled headers to cope with tentative definitions in the future. llvm-svn: 69681 2009-04-22 01:11:58 +08:00			`struct S s;`
