2010-04-08Rename CGVtable files to CGVTables.Anders Carlsson

2010-04-08Clarify an assert.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100776 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
2010-04-03Don't produce a vtable for a class if we have an explicit template ↵Rafael Espindola
instantiation declaration and no key function. We will produce the vtable at the explicit template instantiation. Fixes PR6748 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100266 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30the big refactoring bits of PR3782.Rafael Espindola
This introduces FunctionType::ExtInfo to hold the calling convention and the noreturn attribute. The next patch will extend it to include the regparm attribute and fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99920 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Don't produce a vtable if we are just instantiating a method and theRafael Espindola
class has no key function. Fix PR6738. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99900 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30Flip the switch and use the new vtable layout code for everything. I've ↵Anders Carlsson
verified that this passes a self-host but I'll let the bots self host as well before removing the now dead code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99861 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99812 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-29More vtable work - it's not possible to use the new vtable code for ↵Anders Carlsson
everything by setting a flag inside CGVtable.cpp. My plan is to run some tests and bootstrap and once that's done flip the bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99804 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29Only add thunks for the most derived class. This fixes some link errors I ↵Anders Carlsson
was seeing in files generated by the vtable tester utility. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99801 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-29Make sure to sort the vtable thunks by their vtable index :) With this we ↵Anders Carlsson
now pass the test from http://www.codesourcery.com/public/cxx-abi/abi-examples.html#vtable-ctor successfully. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99792 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29Two bug fixes, we weren't updating the thunk index when creating the vtable ↵Anders Carlsson
initializer and we weren't storing the secondary virtual pointer indices. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99786 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99581 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Don't add address points for virtual primary bases that aren't primary bases ↵Anders Carlsson
in the complete class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99555 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25When -fdump-vtable-layouts is specified, construction vtable initializers ↵Anders Carlsson
will be generated using the new vtable layout code. (The code is still not completely in place but this is a huge step forward). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99508 91177308-0d34-0410-b5e6-96231b3b80d8
