[PATCH 33/40] target_ops/C++: The rest of the BSD targets
- From: Pedro Alves <palves at redhat dot com>
- To: gdb-patches at sourceware dot org
- Date: Sat, 14 Apr 2018 20:09:46 +0100
- Subject: [PATCH 33/40] target_ops/C++: The rest of the BSD targets
- References: <20180414190953.24481-1-palves@redhat.com>
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between the
different BSDs. Current, all that is stiched together to form a final
target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target
functions etc.
This patch converts the rest of the BSD targets to C++ified target_ops.
Adds new obsd_nat_target and nbsd_nat_target targets similar to
fbsd_nat_target introduced a couple patches ago, a sparc_target mixin
similar to the one introduced in the previous patch for x86, and then
stiches everything together into final targets.
Unfortunately, I'm not able to test most of this. I was able to build
GDB for AMD64 NetBSD on the compile farm, but that's it.
