* [weak vtables] Remove a bunch of weak vtablesJuergen Ributzka2013-11-19
| | | | | | | | | | | | This patch removes most of the trivial cases of weak vtables by pinning them to a single object file. The memory leaks in this version have been fixed. Thanks Alexey for pointing them out. Differential Revision: http://llvm-reviews.chandlerc.com/D2068 Reviewed by Andy git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195064 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert r194865 and r194874.Alexey Samsonov2013-11-18
| | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194997 91177308-0d34-0410-b5e6-96231b3b80d8

* ISelDAG: spot chain cycles involving MachineNodesTim Northover2013-09-22
| | | | | | | | | | | | | | | | | Previously, the DAGISel function WalkChainUsers was spotting that it had entered already-selected territory by whether a node was a MachineNode (amongst other things). Since it's fairly common practice to insert MachineNodes during ISelLowering, this was not the correct check. Looking around, it seems that other nodes get their NodeId set to -1 upon selection, so this makes sure the same thing happens to all MachineNodes and uses that characteristic to determine whether we should stop looking for a loop during selection. This should fix PR15840. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191165 91177308-0d34-0410-b5e6-96231b3b80d8

* [Sparc] Correctly handle call to functions with ReturnsTwice attribute.Venkatraman Govindaraju2013-09-05
| | | | | | | | | | | | | | In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7) using the stored %fp and register windows. However, this does not guarantee that the longjmp will restore the registers, as they were when the setjmp was called. This is because these registers may be clobbered after returning from setjmp, but before calling longjmp. This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190033 91177308-0d34-0410-b5e6-96231b3b80d8
