Mike Stump d538a6d364 Remove some dead code. 
llvm-svn: 92123
 2009-12-24 07:29:41 +00:00
Anders Carlsson 3f4336cb1f Rename GetAddrOfRTTI to GetAddrOfRTTIDescriptor. Remove the overload that takes a CXXRecordDecl since we were just creating a QualType from it anyway. 
llvm-svn: 91590
 2009-12-17 07:09:17 +00:00
Eli Friedman 2151725325 Fix a small bug in ComputeMethodVtableIndices. 
llvm-svn: 91411
 2009-12-15 03:31:17 +00:00
Eli Friedman 3ace52b3a7 Fix linkage of type info and vtable for classes without linkage. 
llvm-svn: 91152
 2009-12-11 20:48:18 +00:00
Anders Carlsson fd7dfeb779 Improve linkage of RTTI data structures. Introduce CodeGenModule::GetAddrOfRTTI which figures out the right linkage of the RTTI information for the given type and whether it should be defined or not. I will migrate clients over to GetAddrOfRTTI in subsequent commits (with tests). 
llvm-svn: 91098
 2009-12-11 02:46:30 +00:00
Eli Friedman 48c6b0d14f Slight tweak to vtable linkage. 
llvm-svn: 90832
 2009-12-08 04:09:14 +00:00
Eli Friedman 31bc3ad275 A bunch more thunk fixes from misc testing. 
(Yes, I do intend to commit some tests for this.)

llvm-svn: 90818
 2009-12-07 23:56:34 +00:00
Anders Carlsson e1b3e6292a It's OK to try to emit a vtable definition more than once. Fixes PR5697. 
llvm-svn: 90751
 2009-12-07 07:59:52 +00:00
Eli Friedman c0dacee1e0 Erm, revert for the moment; I didn't test this as thoroughly as I should have 
(although it does pass regression tests).

llvm-svn: 90747
 2009-12-07 04:45:50 +00:00
Eli Friedman c5d3a6ae3d Tweak the formula for non-virtual offsets to something which appears a bit 
more accurate.

llvm-svn: 90723
 2009-12-06 22:33:51 +00:00
Eli Friedman 8174f2c23c Work-in-progess rewrite of thunks: move thunk generation outside of vtable 
generation, and make sure we generate thunks when the function is defined
rather than when the vtable is defined.

llvm-svn: 90722
 2009-12-06 22:01:30 +00:00
Anders Carlsson fe5f7d916f Set the correct linkage for VTTs as well.

llvm-svn: 90687
 2009-12-06 00:53:22 +00:00

llvm-svn: 90686
 2009-12-06 00:23:49 +00:00
Anders Carlsson 7e28c5f2e2 Make GenerateVtable a private member function of CGVtableInfo. 
llvm-svn: 90684
 2009-12-06 00:01:05 +00:00
Anders Carlsson 4ed44eb7d9 Only emit the vtable definition if the class has a key function and we're emitting it, or if the class doesn't have a key function and we are emitting the complete constructor. 
llvm-svn: 90681
 2009-12-05 22:42:54 +00:00
Anders Carlsson 0ab79e22ab If a class does not have a key function, its linkage should be weak_odr. 
llvm-svn: 90680
 2009-12-05 22:24:38 +00:00
Anders Carlsson 58b271d450 Use createGlobalVariable for creating vtable variables too.

llvm-svn: 90672

Anders Carlsson 78c2898e02 Change getCtorVtable to not return the address point offset, but the global variable.

 2009-12-05 20:42:53 +00:00
Anders Carlsson 21bbc1e705 Factor vtable related GlobalVariable creation out into a separate function. Add vtable linkage test. 
llvm-svn: 90667
 2009-12-05 17:04:47 +00:00
Eli Friedman 6c08ce7706 Skip actually generating the vtable unless we are defining it. This avoids 
the side-effects of generating the methods in the vtable (including PR5676).

llvm-svn: 90635
 2009-12-05 01:05:03 +00:00
