getcontext on Linux PPC64

[Sergiy Kyrylkov]

Hi,

Since getcontext is not implemented on Linux the following thing worked for
me on Linux PPC

void cTrapHandler(int signum, siginfo_t *siginfo, void* arg3) {
   sigcontext* context = getLinuxSavedContext(signum, arg3);
   printf("SIGSEGV = %d\n", SIGSEGV);
   printf("signum = %d\n", signum);
   printf("(siginfo->si_addr) = 0x%p\n", (siginfo->si_addr));
   .....
}

sigcontext* getLinuxSavedContext(int signum, void* arg3) {
  return &((ucontext_t*)arg3)->uc_mcontext;
}

It doesn't seem to work on Linux PPC64.  Instead of getting the correct
faulting address:

SIGSEGV = 11
Signum = 11
(siginfo->si_addr) = 0xffffffff4

like it was on the 32-bit PPC, I get

SIGSEGV = 11
Signum = 11
(siginfo->si_addr) = 0x0000000000000380 (instead of 0xffffffffffffffe8)

which is totally wrong.

Does somebody have any idea what will work on Linux PPC64?

Sergiy
