The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

/* Middle-to-low level generation of rtx code and insns.
This file contains the functions `gen_rtx', `gen_reg_rtx'
and `gen_label_rtx' that are the usual ways of creating rtl
expressions for most purposes.
It also has the functions for creating insns and linking
them in the doubly-linked chain.
The patterns of the insns are created by machine-dependent
routines in insn-emit.c, which is generated automatically from
the machine description. These routines use `gen_rtx' to make
the individual rtx's of the pattern; what is machine dependent
is the kind of rtx's they make and what arguments they use. */

All of the emit_foo global entry points accept an object
X which is either an insn list or a PATTERN of a single
instruction.
There are thus a few canonical ways to generate code and
emit it at a specific place in the instruction stream. For
example, consider the instruction named SPOT and the fact that
we would like to emit some instructions before SPOT. We might
do it like this:
start_sequence ();
... emit the new instructions ...
insns_head = get_insns ();
end_sequence ();
emit_insn_before (insns_head, SPOT);
It used to be common to generate SEQUENCE rtl instead, but that
is a relic of the past which no longer occurs. The reason is that
SEQUENCE rtl results in much fragmented RTL memory since the SEQUENCE
generated would almost certainly die right after it was created. */
