[Valgrind-developers] Porting valgrind to FreeBSD

[Doug R. <df...@nl...>]

Since I've had a bit of festive spare time available, I thought I would
attempt to port valgrind 2.1.0 to FreeBSD-5.x. After a bit of a
struggle, two falls and a submission, I have most of it working well
enough to pass most of the tests (with the notable exception of the
pthread stuff which I haven't even tried to port yet).

Is there any interest here in merging support for FreeBSD? Most of the
syscall hairy bits should also help to get NetBSD and OpenBSD going too.
I have ended up with a bit of an ifdef tangle in a few places but that
might be best managed by simply forking a few of the source files
(vg_kerneliface.h, vg_syscalls.c and similar). My patch is currently
about 130k (as a unified diff against 2.1.0.

Anyway, whether you want the port or not, I'd like to thank the valgrind
developers for an excellent tool which I've used to find lots of ugly
problems in my own programs on Linux (and now BSD as well).
