2010-05-27When deciding whether a deferred declaration has already been emitted,John McCall

2010-05-25IRgen: Add a stub class for generating ABI-specific C++ code.Charles Davis
This class only supports name mangling (which is apparently used during C/ObjC codegen). For now only the Itanium C++ ABI is supported. Patches to add a second C++ ABI are forthcoming. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104630 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-25If a function definition has any sort of weak linkage, its static localJohn McCall
variables should have that linkage. Otherwise, its static local variables should have internal linkage. To avoid computing this excessively, set a function's linkage before we emit code for it. Previously we were assigning weak linkage to the static variables of static inline functions in C++, with predictably terrible results. This fixes that and also gives better linkage than 'weak' when merging is required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104581 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-13Disable the available_externally optimization for inline virtualDouglas Gregor
methods for which the key function is guaranteed to be in another translation unit. Unfortunately, this guarantee isn't the case when dealing with shared libraries that fail to export these virtual method definitions. I'm reopening PR6747 so we can consider this again at a later point in time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103741 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-13Rework when and how vtables are emitted, by tracking where vtables areDouglas Gregor
"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. Fixes PR7114 and PR6564. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103718 91177308-0d34-0410-b5e6-96231b3b80d8
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
