PATCH ARM/NetBSD handle elf core files
- From: Richard Earnshaw <rearnsha at arm dot com>

- Subject: PATCH ARM/NetBSD handle elf core files
- Organization: ARM Ltd.
- Reply-to: Richard dot Earnshaw at arm dot com
Now we can read elf core files on ARM/NetBSD as well.
2002-02-21 Richard Earnshaw <rearnsha@arm.com>
* Makefile.in (armnbsd-nat.o): Update dependencies.
* armnbsd-nat.c (supply_gregset): New function. Common code to
supply the integer register set.
(supply_fparegset): New function. Similar for FPA registers.
(fetch_regs, fetch_fp_regs): Use them.
(fetch_core_registers): Likewise.
(fetch_elfcore_registers): New function.
(arm_netbsd_elfcore_fns): New core-file type specification.
(_initialize_arm_netbsd_nat): Register it.
