This adds a port to Linux on the IBM Z platform (a.k.a s390x). It only supports the 64-bit ABI. Most functionality is working and all the tests pass with the exception of the coredump tests*. Unwinding is only supported if DWARF unwind information is present. libunwind can't currently make use of the backchain (if present). The getcontext/setcontext functions only preserve/restore a subset of registers. Currently this only consists of callee-saved registers and some parameter registers. Vector registers and access registers are not saved (and aren't callee- saved) by getcontext and cannot currently be modified. They will however be restored unmodified after resuming a context from a signal handler. There is no special libunwind support for setjmp, the functionality is emulated using glibc (I think all the ports do this for modern Linux kernels). * Unwinding on s390x requires floating point register access which the coredump library doesn't currently support. |
