These functions are taken from the g++ unwinder library (libgcc_s.so). Declaring them like I did is really bad. I'm thinking of something like: typedef void function_regis...

Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the
