xmalloc() and xrealloc() and the mixed usage of xmalloc in some .c's from
libiberty.a and other .c's from libreadline.so produces an unusable binary

While I am here, preventatively move other libs in the link order.

Correct backtrace was made more complex when the new signal trampoline
was introduced to support more than 32 signals, while keeping a modified
version of the old signal trampoline.
The 'where' command will now show:
#2 <signal handler called>
where appropiate.

Rev 1.2 changed the default emulation from ``elf64_sparc'' to ``elf32_sparc''
and I never noticed it after my review of rev 1.1. Backing the change of
the default emulation out, and Wa-la!, I can now build a native [and usable]
binutils. WTF, the "-m elf64_sparc" parameter handed to `ld' by `gcc'
wasn't DTRT is beyond me.
Presumably the issue was with arparse.[ch]. Those are now in FREEBSD-Xlist
and FREEBSD-deletelist. So we do not import the Bison produced files that
was causing the problem.

These changes are most helpful during `make buildworld' so that the shared
libs built in the middle of `make buildworld' are used vs. the ones in
/usr/lib on the build machine.

code in ipl.s and icu_ipl.s that used them was removed when the
interrupt thread system was committed. Debuggers also knew about
Xresume* because these labels hide the real names of the interrupt
handlers (Xintr*), and debuggers need to special-case interrupt
handlers to get the interrupt frame.
Both gdb and ddb will now use the Xintr* and Xfastintr* symbols to
detect interrupt frames. Fast interrupt frames were never identified
correctly before, so this fixes the problem of the running stack
frame getting lost in a ddb or gdb trace generated from a fast
interrupt - e.g. when debugging a simple infinite loop in the kernel
using a serial console, the frame containing the loop would never
appear in a gdb or ddb trace.

bug in lib/libc/gen/basename.c rev 1.1. There is no way for us to test
what revision of basename() we have in libc, thus this change.

misuse of /usr/src/include headers. This REALLY fixes
the 20010919 src/UPDATING entry.
With this patch the 4.2-RELEASE box was able to survive
the 5.0-CURRENT "make world".
Beat over the head with this patch: obrien
The version of the kernel has no bearing on what is in libc.
We now search for basename in libc to determin if we need to include
the libiberty version in the build.
This is all still a bit bogus as it will (like the sysctl method) cause
basename.o to be linked into the cross-build as well as the host build. It
would probably be better to test if we were doing the initial host build and
unconditionally include that. Once we've generated the target libc we know
that basename is available. (maybe test for $TOOLS_PREFIX or something).

This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

- Use offsets into struct globaldata directly to find per-cpu variables,

I've been in some conversation with Brian about this, and this solution
seems to be the most appropriate one.

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.
