accessing Alpha CPU registers from panic()

I am working on porting the SGI crash tools to Alpha. Since the CPU registers
aren't available from within the panic() call, I need to grab them directly.
How do I do this? The equivalent i386 code is:

/* save the dump specific esp/eip */
/* For Alpha, save PC (Program Counter) and RA */
__asm__ __volatile__("
pushl %%eax\n
movl %%esp, %%eax\n
movl %%eax, %0\n
popl %%eax\n"
: "=g" (dump_header.dh_esp)
);
__asm__ __volatile__("pushl %eax\n");
__dump_save_panic_regs();
__asm__ __volatile__("popl %eax\n");

Pointers to online resources are greatly welcomed also.
