Hi, many people suggest that if we want llvm to support sjlj-eh, we should modify the llvm-gcc to generate sjlj-style IR. yeah, I'm digging into the llvm-gcc now. there are some functions, at the llvm-gcc e.g TreeToLLVM::CreateExceptionValues() , BasicBlock *TreeToLLVM::getPostPad(unsigned RegionNo), void TreeToLLVM::EmitLandingPads(), void TreeToLLVM::EmitPostPads() , void TreeToLLVM::EmitUnwindBlock() the above functions are relative for llvm-gcc generate the exception-IR, but for dwarf-style! so we should change these above func...

.../ The type is the type of the expression. Dest = BitCastToType(Dest, PointerType::getUnqual(ConvertType(TREE_TYPE(exp)))); - return LValue(Dest); + return LValue(Dest, S->getAlignment()); } } LValue TreeToLLVM::EmitLV_EXC_PTR_EXPR(tree exp) { CreateExceptionValues(); // Cast the address pointer to the expected type. - return BitCastToType(ExceptionValue, - PointerType::getUnqual(ConvertType(TREE_TYPE(exp)))); + unsigned Alignment = TD.getABITypeAlignment(cast<PointerType>(ExceptionValue-> +...
