end of the include searching. We really need a real fix for the issue of
which set of headers to use in compiling the cross-tools -- /usr/include,
or /usr/src/include.
call and trap entry points so they're easy to find and change
- Use the cpuhead and allcpu list to locate globaldata for the current
cpu, rather than SMP_prvspace or __globaldata
- Use offsets into struct globaldata directly to find per-cpu variables,
rather than symbols in globals.o

when using gdb on a remote target. The fix is to restrict PT_GETDBREGS
calls to `child' and `freebsd-uthreads' targets solely.
I've been in some conversation with Brian about this, and this solution
seems to be the most appropriate one.

`wait.h' that was in contrib/binutils/, however this wait.h went away with
bintuils 2.10.0 so I `cvs rm'ed it. Now we find gdb will not build. This
binutils wait.h contained nothing we didn't already have in <sys/wait.h>.
So just hack a symlink to it.
with Brian's kernel support for i386 debug registers. This makes
watchpoints actually usable for real-life problems. Note: you can
only set watchpoints on 1-, 2- or 4-byte locations, gdb automatically
falls back to [sloooow] software watchpoints when attempting to use
them on variables which don't fit into this category. To circumvent
this, one can use the following hack:
watch *(int *)0x<some address>
David O'Brien is IMHO considering to get this fully integrated into the
official GDB, but as long as we've got the i386/* files sitting around
in our private FreeBSD tree here, the feature can now be tested more
extensively, so i'm committing this for the time being.
This work has been done in order to debug a tix toolkit problem, thus
it has been sponsored by teh Deutsche Post AG.

libraries in LDADD so that `make checkdpadd' doesn't report non-errors.
Fixed some style bugs (the usual ones for DPADD and LDADD, and misformatting
of $FreeBSD$).
The target machine is represented by TARGET_ARCH. MACHINE_ARCH always
represents the host machine. When TARGET_ARCH is not defined, it is
assumed to be equal to MACHINE_ARCH. This means that we're building a
native toolset by default. We're creating cross-compilation tools when
MACHINE_ARCH != TARGET_ARCH.
TARGET_ARCH is defined when building binutils as part of the bootstrap
build and is set to reflect the architecture we're currently cross-
building. With this change binutils is ready for cross-building.
All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.

The new directories with freebsdelf suffixes now have freebsd suffixes

directory to /usr/cross/${MACHINE_ARCH}-freebsdelf/usr/lib so that
the cross tools behave the same way that the host versions do. When
building cross tools, Cygnus doesn't set the default library directory.
This doesn't suit FreeBSD IMHO.
Add WinNT emulation support too. You only get this if you've set
BINUTILSDISTDIR because the contrib/binutils repository doesn't
contain the required sources.

gas for i386 targeted to NT for those (like me) who have to do work
targeted to NT, but can't stand actually looking at it all day long.
I cross build apps on FreeBSD and just run them on NT later. Life is
better that way.
Allow for the case where the host architecture might also be listed
in CROSS_ARCH, so don't do things twice. This situation can arise if you
want NT support in binutils (CROSS_ARCH=i386 CROSS_FORMAT=winnt).
* Update build for gdbserver and gdbreplay to work under binutils
* Fix gdbserver to use PT_GETREGS etc to access registers, removing the
dependancy on the u-area.
* Make gdbserver work on the alpha.
