I am trying to implement instruction scheduling for the DLX RISC
architecture described in "Computer Architecture:  A Quantitative
Approach" by Hennessy & Patterson.  The DLX looks a LOT like a MIPSco
Rx000.  I'm using gcc 1.37.1.

There is a file called dbranch.c, which is activated by defining
HAVE_DELAYED_BRANCH in tm.h, however I could not find any tm.h file in
the distribution that has this defined, not even the MIPS or SPARC
files.  Has anyone tried to use this?

Has anyone succeeded in getting delayed branches to work, or is this
still experimental software?

Thanks for any info,
	Crispin
