	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'.

 | |
|    to test for its presence and this word will contain garbage for too-old
