I do not care about those two targets, but I do care for the EBCDIC support. We
(at FSC) are using GCC as an internal tool. It runs on a system with both host
and target being EBCDIC.

I have run into a few problems with the EBCDIC support (in GCC 3.0.4):

In cppinit.c the static function "opt_comp" needs the definiton of "p1" and "p2"
defined later in this file. The call to qsort needs the size of "struct
cl_option" defined later in this file. I could solve this problem by
re-ordering the function definitions in this file.

In libiberty/safe-ctype.c I added a complete case for EBCDIC, using a check like
#elif '\n' == 0x15 && ' ' == 0x40 && '0' == 0xF0 \
  && 'A' == 0xC1 && 'a' == 0x81 && '!' == 0x5A \
  && 'J' == 0xD1 && 'j' == 0x91 && EOF == -1

I had to re-create c-parse.c with an EBCDIC bison.

In tradcif.y use TARGET_ESC instead of hardcoded "033".


Please do not to drop the EBCDIC support.

Thanks

Hmmm, doesn't really look gone.

These all seem reasonable from my perspective.

Please don't depreciate unless you can find a new vax maintainer.  The
machine used for testing runs proprietary software so it can't be updated
to netbsd.

I thought all the wince ports are based on coff?

And since wince is so bad for debugging, it's good to have a coff target
that you can use as an analogy for testing and debugging.

ACT is definitely *not* stepping up to the place to act as maintainer. It
is possibloe that some time in the future a current user of GCC 2 with the
i960 wlil be interested in moving to GCC 3, but if that happens, the port
can be revived at that time.

It's time to decide which targets should be deprecated for the 3.3
release and removed in 3.4.

vax-*-vms* has already gone, and there was much rejoicing.

These targets were proposed for deprecation in 3.1 but preserved
because there might still be interest:

  mips-sni-sysv4
  m88k-*-*
  ns32k-*-*
  romp-*-*

Of these, only ns32k has seen any activity other than global cleanups
since the 3.1 release.  So I propose to remove ns32k-*-* from the
deprecation list, and pull the plug on the others.

There was some discussion of dropping i960-*-*; I didn't see it come
to a conclusion.

The i370 and s390 targets are for the same architecture.  They are not
entirely redundant; each supports operating environments that the
other doesn't.  However, the s390 target is actively maintained, the
i370 isn't, and HOST_EBCDIC doesn't really work.  I would like to
suggest, therefore, that we drop (a) the i370, and (b) any pretense of
supporting EBCDIC as the primary character encoding for the host.  (It
is much, much easier to support it in the target.)

It doesn't appear to me that we have any other dead architectures.
The vax and the pdp11 are arguable, but they do have active
maintainers.

Moving on to specific targets that might be worth dropping, here is my
list.  Some of these may well be live; I'm pretty ruthless.  Some of
these canonical names are not actually used as such, they're just
evocative (foo-*-netbsd*aout*, for instance, actually manifests as one
stanza for foo-*-netbsdelf* followed by another for foo-*-netbsd* -
it's my intention to propose deprecation of the a.out target only).
