Update.
2000-01-05 Philip Blundell <philb@gnu.org>
* sysdeps/arm/frame.h: New file.
* sysdeps/generic/frame.h: Likewise.
* sysdeps/generic/segfault.c (struct layout): Delete definition;
include the above file instead.
* sysdeps/generic/backtrace.c (struct layout): Likewise.
(__backtrace): Use ADVANCE_STACK_FRAME.
* sysdeps/unix/sysv/linux/arm/sigcontextinfo.h
(ADVANCE_STACK_FRAME): New macro.
(GET_FRAME): Apply above to returned value.
* sysdeps/unix/sysv/linux/arm/bits/armsigctx.h: Add `fault_address'.
