...from libobjc2. This function is in a shared library (libgnustepbase), and here's the start of its entry in the execption table: GCC_except_table20: .Lexception20: .byte 255 @ @LPStart Encoding = omit .byte 0 @ @TType Encoding = absptr .ascii "\314\001" @ @TType base offset So it definitely uses DW_EH_PE_absptr as TType encoding. The personality routine in the Objective-C runtime library reads the type table record and interpretes the data in it as an absolute pointer that is used without any...

Hi, I'm trying to get exception handling working in my compiler targetting LLVM. I've been working from the LLVM exception handling documentation (including http://llvm.org/docs/ExceptionHandling.html and http://wiki.llvm.org/HowTo:_Build_JIT_based_Exception_mechanism) and looking at g++-llvm's output. I've been trying to get a minimal test function to work, which simply invokes
