I'm writing a compiler, using LLVM, that includes exception handling. I link the results via gcc (convenient option). If I produce static executables all is well, but my LSDA in a shared module (with PIC), is incorrect. I've traced through the libgcc personality function but can't figure out where I've gone wrong. My LSDA parser seems valid: static builds work, and I do get the correct number of action records, and the type offsets seem okay. But the type table is pointing to an invalid location, a really small address. It's as though it isn't getting its relocated address. Does this sound like a common problem? Am I missing something simple, like linker flags? Perhaps an init function of some kind must be called in the shared library (I define my own init/fini functions). Platform is GNU/Linux x86_64. gcc/ld flags: --eh-frame-hdr --build-id --export-dynamic -shared Sorry if my question isn't strictly gcc related, but I'm not sure where else somebody might know the answer. I also realize it may be very hard to assist, since the effect is a combination of my personality code, LLVM EH generation, the linker, and gcc unwinding. -- edA-qa mort-ora-y -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Sign: Please digitally sign your emails.
