2009-12-02More exception handling improvements... WIP.Mike Stump
Highlights include: Add a helper to generate __cxa_free_exception and _ZSt9terminatev. Add a region to handle EH object deallocation for ctor failures for throw. Add a terminate handler for __cxa_end_catch. A framework for adding cleanup actions for the exceptional edges only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90305 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Much work on try/catch statement. WIP.Mike Stump
Highlights include: Fix __cxa_begin_catch so it now returns a value. Added getUnwindResumeOrRethrowFn helper to build up calls to _Unwind_Resume_or_Rethrow. Broke out object copying code into CopyObject from EmitCXXThrowExpr. Built up another version of CopyObject that can copy from memory for use in the catch parameter code. RTTI generation for type matching for catch. Code to check for the type match for catch. Code to generate the catch parameter, WIP, need make sure references and pointers and copy ctors work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90205 91177308-0d34-0410-b5e6-96231b3b80d8
