2010-05-06Do not give implicitly-defined virtual members functionsDouglas Gregor
available_externally linkage, since they may not have been given a strong definition in another translation unit. Without this patch, the following test case fails to link with a GCC-compiled libstdc++: #include <sstream> int main() { std::basic_stringbuf<char> bs; } Fixes the last problem with the Boost.IO library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103208 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-08Eliminate excessive PCH deserialization caused by the search forDouglas Gregor
__cxxabiv1::__fundamental_type_info in every translation unit. Previously, we would perform name lookup for __cxxabiv1::__fundamental_type_info at the end of IRGen for a each translation unit, to determine whether it was present. If so, we we produce type information for all of the fundamental types. However, this name lookup causes PCH deserialization of a significant part of the translation unit, which has a woeful impact on performance. With this change, we now look at each record type after we've generated its vtable to see if it is __cxxabiv1::__fundamental_type_info. If so, we generate type info for all of the fundamental types. This works because __cxxabiv1::__fundamental_type_info should always have a key function (typically the virtual destructor), that will be defined once in the support library. The fundamental type information will end up there. Fixes <rdar://problem/7840011>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100772 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19Change CodeGenModule to rely on the Module's symbol table instead ofJohn McCall
shadowing it in the GlobalDeclMap. Eliminates the string-uniquing requirement for mangled names, which should help C++ codegen times a little. Forces us to do string lookups instead of pointer lookups, which might hurt codegen times a little across the board. We'll see how it plays out. Removing the string-uniquing requirement implicitly fixes any bugs like PR6635 which arose from the fact that we had multiple uniquing tables for different kinds of identifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99012 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13Give explicit template instantiations weak ODR linkage. FormerDouglas Gregor

2010-02-23Perform two more constructor/destructor code-size optimizations:John McCall
1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96842 91177308-0d34-0410-b5e6-96231b3b80d8
