2011-03-27We were emitting construction v-tables with internal linkage all the time.John McCall
Emit them instead with the linkage of the VTT. I'm actually really ambivalent about this; it's what GCC does, but outside of improving code size (if the linkage is coalescing), I'm not sure it's at all relevant. Construction vtables are naturally referenced only by the VTT, which is itself only referenced by complete-object constructors and destructors; giving the construction vtables possibly-external linkage is important if you have an optimization that drills through the VTT to a reference to a particular construction vtable which it cannot just emit itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128374 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-26On Mac OS X, the presence of an 'availability' attribute for thatDouglas Gregor
platform implies default visibility. To achieve these, refactor our lookup of explicit visibility so that we search for both an explicit VisibilityAttr and an appropriate AvailabilityAttr, favoring the VisibilityAttr if it is present. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128336 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-09Use the "undergoes default argument promotion" bit on parameters toJohn McCall
simplify the logic of initializing function parameters so that we don't need both a variable declaration and a type in FunctionArgList. This also means that we need to propagate the CGFunctionInfo down in a lot of places rather than recalculating it from the FAL. There's more we can do to eliminate redundancy here, and I've left FIXMEs behind to do it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127314 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-06Fix self-host; if a thunk already exists and has available_externally ↵Anders Carlsson
linkage, we should change its linkage instead of asserting. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124986 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-06When building with optimizations, emit thunks with available_externally ↵Anders Carlsson
linkage so devirtualized function calls can also be de-thunked. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124984 91177308-0d34-0410-b5e6-96231b3b80d8

GetOrCreateLLVMFunction so that we won't assert when building a thunk for an implicit virtual member function that is not marked used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124967 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-05Re-land r124768, with a fix for PR9130.Anders Carlsson
We now emit everything except unused implicit virtual member functions when building the vtable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124935 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-03Revert 124768.Rafael Espindola
This reopens PR99114, but that one at least can be avoided with an #include. PR9130 cannot. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124780 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-03Don't try to mark virtual members referenced for classes where the key functionAnders Carlsson
is not defined in the current translation unit. Doing so lead to compile errors such as PR9114. Instead, when CodeGen is building the vtable, don't try to emit a definition for functions that aren't marked used in the current translation unit. Fixes PR9114. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124768 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-30When building with optimizations, emit vtables where the key is not in the Anders Carlsson
current translation unit as available_externally. This helps devirtualize the second example in PR3100, comment 18: struct S { S() {}; virtual void xyzzy(); }; inline void foo(S *s) { s->xyzzy(); } void bar() { S s; foo(&s); } This involved four major changes: 1. In DefineUsedVTables, always mark virtual member functions as referenced for non-template classes and class template specializations. 2. In CodeGenVTables::ShouldEmitVTableInThisTU return true if optimizations are enabled, even if the key function is not implemented in this translation unit. We don't ever do this for code compiled with -fapple-kext, because we don't ever want to devirtualize virtual member function calls in that case. 3. Give the correct linkage for vtables where the key function is not defined. 4. Update the linkage for RTTI structures when necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124565 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-09When re-using a vtable slot for the nearest overridden method, just becauseJohn McCall
there's no return adjustment from the overridden to the overrider doesn't mean there isn't a return adjustment from the overrider to the final overrider. This matters if we're emitting a virtual this-adjustment thunk because the overrider virtually inherits from the class providing the nearest overridden method. Do the appropriate return adjustment in this case. Fixes PR7611. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118466 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-30Better solution: calculate the visibility of functions and variablesJohn McCall
