* Amazing that there are still issues with the fields of anonymous struct/unions..Argyrios Kyrtzidis2011-01-311-5/+29
| | | | | | Allow taking the address of such a field for a pointer-to-member constant. Fixes rdar://8818236. llvm-svn: 124575
* When building with optimizations, emit vtables where the key is not in the Anders Carlsson2011-01-303-1/+68
| | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 124565

* Give VTTs the right visibility.Anders Carlsson2011-01-291-0/+3
| | | | llvm-svn: 124540
* Make emitting a VTT a two-step process, much like emitting a VTable. You ↵Anders Carlsson2011-01-295-51/+46
| | | | | | first get the address of the VTT, and then pass it to EmitVTTDefinition. llvm-svn: 124539
* Use CGM.CreateOrReplaceCXXRuntimeVariable in CGVTables.cppAnders Carlsson2011-01-292-48/+5
| | | | llvm-svn: 124538
* Add a new function, to be used by CGRTTI, CGVTables and CGVTT (which each ↵Anders Carlsson2011-01-292-0/+47
| | | | | | has their own copy of this code). llvm-svn: 124537
* Replace a literal '8' with getCharWidth().Ken Dyck2011-01-291-2/+3
| | | | llvm-svn: 124536
* Remove IsDefinition from CodeGenModule::setTypeVisibility; it is always true.Anders Carlsson2011-01-294-6/+5

* When trying to get the most derived class, don't assume that we can ignore ↵Anders Carlsson2011-01-291-1/+17

* When calling a virtual member function on a base class and the most derived ↵Anders Carlsson2011-01-291-1/+24

* Convert the exception-freeing cleanup over to the conditional cleanups code,John McCall2011-01-284-119/+88
| | | | | | | | | fixing a crash which probably nobody was ever going to see. In doing so, fix a horrendous number of problems with the conditional-cleanups code. Also, make conditional cleanups re-use the cleanup's activation variable, which avoids some unfortunate repetitiveness. llvm-svn: 124481

| | | | | | | | | non-class prvalues actually require the realization of a temporary. For everything else, we already have an lvalue (or class prvalue) in the subexpression. Note: we're missing some move elision in this case. I'll tackle that next. llvm-svn: 124453
