* Fix bitcode desynchronization when loading a PCH containing a class templateRichard Smith2013-05-231-0/+3
| | | | | | | | | | | | specialization with modules enabled. Just don't merge them at all for now; we'll revisit this when support for template merging is added. In passing, make Decl::dump() a little safer to use with PCH/modules, by making it not deserialize any additional declarations. From a debugger you can call decls_begin() or similar first if you want to dump all child decls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@182544 91177308-0d34-0410-b5e6-96231b3b80d8

* C++ constant expression handling: eagerly instantiate static const integral dataRichard Smith2011-12-211-1/+6
| | | | | | | | | members of class templates so that their values can be used in ICEs. This required reverting r105465, to get such instantiated members to be included in serialized ASTs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147023 91177308-0d34-0410-b5e6-96231b3b80d8
* Completely re-implement (de-)serialization of declarationDouglas Gregor2011-12-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | chains. The previous implementation relied heavily on the declaration chain being stored as a (circular) linked list on disk, as it is in memory. However, when deserializing from multiple modules, the different chains could get mixed up, leading to broken declaration chains. The new solution keeps track of the first and last declarations in the chain for each module file. When we load a declaration, we search all of the module files for redeclarations of that declaration, then splice together all of the lists into a coherent whole (along with any redeclarations that were actually parsed). As a drive-by fix, (de-)serialize the redeclaration chains of TypedefNameDecls, which had somehow gotten missed previously. Add a test of this serialization. This new scheme creates a redeclaration table that is fairly large in the PCH file (on the order of 400k for Cocoa.h's 12MB PCH file). The table is mmap'd in and searched via a binary search, but it's still quite large. A future tweak will eliminate entries for declarations that have no redeclarations anywhere, and should drastically reduce the size of this table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146841 91177308-0d34-0410-b5e6-96231b3b80d8
