I am trying to port ksh (version 11/16/88d) to a DG 6220.
We are using GNU GCC version 1.37.23 (88k, Aug 15 1990) compiled
by GNU C version 1.37.
Here's the problem: The assembler, as, gags on msg.s, which was created
by gcc from msg.c.
Here is the pertinent part of msg.c:
/* built in names */
const struct name_value node_names[] =
{
"PATH", NULL, 0,
"PS1", NULL, 0,
"PS2", "> ", N_FREE,
.
. (lots of the same deleted, but you get the idea)
.
};
Here is the offending code in msg.s:
@LC0:
string "PATH\000"
align 4
@LC1:
string "PS1\000"
align 4
@LC2:
string "PS2\000"
align 4
.
.
. (lots of the same deleted)
.
_node_names:
word @LC0
word 0
half 0
set .,.+2 <<<<<<<<<<< This is where the error occurs (line 590)
word @LC1
word 0
half 0
set .,.+2 <<<<<<<<<<<
word @LC2
word @LC3
half 4096
set .,.+2 <<<<<<<<<<<
.
.
.
Here is the error message:
as: "msg.s": line 590: operand '.' type mismatch for 'set'
(The error repeats for every set, until the assembler quits due
to too many errors.)
Any ideas?
Thanks,
-Bri

I don't know what the GCC problem could be, but once you get around it, you
will have another problem:
Ksh automatically defines an environment variable named '_' with the path
name to the last command. Unfortunately (at least on DG/UX 4.31) if you have
an environment variable named '_', the 'make' program aborts during its
initialization (presumably when reading in the environment).
I discovered this one while porting a different shell that does the same
thing, but it can be easily reproduced even in /bin/sh by doing something
like:
_=/bin/make
export _
make

The code generator is broken in your gcc. If you have the source, it shouldn't be too difficult to repair, otherwise put a sed script between the compiler and the assembler to change the "set .,.+2" to "align 4" (or better yet, in this case, "half 0") |> word @LC1 |> word 0 |> half 0 |> set .,.+2 <<<<<<<<<<< |> word @LC2 |> word @LC3 |> half 4096 |> set .,.+2 <<<<<<<<<<< |> . |> Thanks, |> |> -Bri |> -- |> --- |> ---- Brian Kenney kenney@hsi.com |> ----- 3M Health Information Systems Wallingford, CT |> ------ you're welcome, scott.

You could try using the Gnu make. I believe i've put the patches here, and i'll make sure they are on csvax.cs.caltech.edu :: pub/M88K soon. - mike
