binutils support for a.out-arm-netbsd target
- To: binutils@sourceware.cygnus.com
- Subject: binutils support for a.out-arm-netbsd target
- From: Roland McGrath <roland@cs.utah.edu>
- Date: Thu, 19 Aug 1999 18:15:32 -0400
- CC: "Leigh B. Stoller" <stoller@cs.utah.edu>
The following patches relative to the current sourceware binutils
enable support for the a.out-arm-netbsd (arm-*-netbsd*) target.
I gleaned the few magic bits from the netbsd-current code (which is based
on 2.9.1), and plopped them into the current binutils. This was enough to
link a.out-arm-netbsd images that the OFW boot loader on DNARDs can boot
properly. I haven't the foggiest idea if it works for actual netbsd
executables, let alone netbsd/a.out dynamic linking; but those are not my
concern (and evidently the netbsd people don't care either, since they
haven't sent in changes). We are using an arm-elf development environment
and only need to convert linked kernel images into netbsd a.out format for
the firmware bootloader we are using (DNARD OFW). For at least that use,
current binutils with these patches seems to be peachy.
Thanks,
Roland
