2010-02-19More refactoring around constructor/destructor code generation.John McCall
Fix some bugs with function-try-blocks and simplify normal try-block code generation. This implementation excludes a deleting destructor's call to operator delete() from the function-try-block, which I believe is correct but which I can't find straightforward support for at a moment's glance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96670 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-10Switch to using -fsjlj-exceptions instead of hard-coding it. Notably, this fixesDaniel Dunbar
calls to the UnwindResumeOrRethrow function for C++/Obj-C exception handling, for Darwin ARM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95787 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-05Standardize the parsing of function type attributes in a way thatJohn McCall
follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95436 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-23There is no such thing as typeinfo for a cv-qualified type. AssertDouglas Gregor
that this is true when mangling, then fix up the various places in Sema and/or CodeGen that need to remove qualifiers. Addresses a linking issue when building LLVM with Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92064 91177308-0d34-0410-b5e6-96231b3b80d8

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
