mycroft b9c785bd44 As seen on tech-toolchain: 
So the problem is thus:

* The {u,}mulsidi3 generate two parallel sets which modify the upper and lower
halves of the target register.

* life_analysis() does not track subregister modifications -- if you don't
modify the whole register with a single set, it considers the register
unused.

The simple, if klugy, solution to this is to stick an explicit clobber in.  It
seems to work.

While doing this, I noticed that constant folding was not happening for
32x32->64 multiplies.  This is because the parallel set generated by
{u,}mulsidi3 cannot be folded at all.  To solve this, I first expand to a
normal multiply, and then use a define_insn_and_split to convert it to the
parallel set after CSE and constant folding.

This patch has also been submitted to GCC bugzilla, but who knows if I'll get
a reply to that.

mrg 2a50c63fdf change the "long" version from "3.3.2-nb1" to "3.3.2 (NetBSD nb1 20031026)" 
which is more inline with what we used previously.

thorpej 75516c03f7 When running mkfixinc.sh, explicltly export SHELL, as well, since on 
some platforms (e.g. OS X), we disable exporting make(1) variables in
the environment due to ARG_MAX limitations.

timestamp skew.

nathanw 804ad776be Pile of cleanups and improvements, including: 
* Use {fill,supply}_{g,fp}regset() routines instead of homegrown
   nbsd_internal_to_reg()/nbsd_reg_to_internal() routines; reduces
   local changes to *-nat files.

 * Use the ptrace(PT_LWPINFO) call to find the set of LWPs in a
   process and map them to threads, and to identify the target of a
   signal event.

 * Consistency sweep on ptid-manipulating macros.

 * More modern GDB integration and removal of redundant functions.

lukem d47cc49cff Add rules to prevent c-parse.c and objc-parse.c from being rebuilt if the 
respective .y file has a newer timestamp (usually due to cvs checkout issues);
the code isn't .OBJDIR friendly, and it's unnecessary in our build envrionment.
