So far if the ucontext structure was obtained by getcontext and co, the return address was stored in general purpose register 14 as it is defined as return address in the ABI. In contrast, the context passed to a signal handler contains the address in psw.addr field. If somebody e.g. wants to dump the address of the context, the origin needs to be known. Now this patch adjusts getcontext and friends and stores the return address also in psw.addr field. Note that setcontext isn't adjusted and it is not supported to pass a ucontext structure from signal-handler to setcontext. We are not able to restore all registers and branching to psw.addr without clobbering one register. |
