gforth: gforth/see.fs

updated copyright years

regexp alternatives fixed
decompiler output for regexp improved

In 'see', disassemle code after ;abi-code

2 bugfixes for see:

- ': array does> if then ;' would fail with 'SEE: Table failure'.

  Reason: c-lit encountering DOES> would incremented the address by only 1
  cell in scan-pass, not the correct 3 cells as in display-pass.

- ;abi-code was treated like 'does>' thus trying to decoding machine code as
   forth code.  For now stop decoding when ;abi-code is encountered.

See works now a little bit better on ;abi-code

Possibility to disassemble ;abi-code, as well (doesn't work yet, since ;abi-code is loaded later)

See works for DOES> again

more work on documenting assembly language stuff

support for using SEE on ABI-CODE definitions

Removed doeshandler in cross.fs

Eliminated unused doeshandler (aka DOESJUMP) field from kernel
  compiler (it's still in cross.fs).  SEE does not know how to
  decompile the result.

bugfix: LOOK works again for xts of primitives
new words: threaded>xt, prim>name, threaded>name (stack effect not final)

Added auto-expanding tib for file reading - the terminal line length remains
limited.

SEE now works again for control structures and strings

worked on SEE
COMPILE, now produces LIT@ and LIT+ again

implemented DECOMPILE-PRIM and use it in (LOOK); SIMPLE-SEE works again
minor bugfix in SIMPLE-SEE
HEAD? now delivers 1 on likely-false positives

eliminated all uses of "lit (abort") (s") (.") outside cross.fs, except one
eliminated (c"); cliteral is now in the kernel.

bugfix: (complex) SEE now works (output quality could be improved, though).

added regression test for signal on broken execute (not working on Linux-PPC)
new error message and code for ticking compile-only words
bug workaround for gforth binary (dynamic superinsts produced wrong code for
    ?dup-0=-branch)

dynamic superinstructions for the code in the image
SEE works again for CODE words

Modified cross to get closer to mixed threading
Added a few debugging aids

Made peephole a configurable option

added SIMPLE-SEE

Further peephole optimization preparation in cross.fs:
- compile calls now works
- compile Create/DOES> better prepaired (doesn't work yet)
- compile Create/Variable doesn't work yet
- no peephole optimization yet
See calls works

SEE bugfix (coming from long names)
NEXTNAME bugfix (but still length restrictions)

make bindist now makes sunsite-compliant package names
updated lsm
prims2x now works on the Alpha
SEE now displays anonymous words as <###> (where ### is the xt)
added CONST-DOES>

added names ID. and .ID for .NAME

changed FSF address in copyright messages

updated copyright dates in many files (not in ec-related files)

documentation changes
fixed bug in cputime

disassembler tweaks

SEE now guesses the length of primitives and code words
It now also works for code words in  direct threading
CODE_ADDRESS now works for direct threaded primitives
    on 386 and (hopefully) PPC

some more adjustments due to the change of >name.

Changed -text in prim
Changed branchtable size to units in cells
Added "bye" in 4stack prims

took exception handling out of the kernel into exceptions.fs
added inline exception handling (TRY...RECOVER...ENDTRY)
added exception handling without affecting sp or fp (PROTECT...ENDPROTECT)

Made some things optional. Perhaps in works sometimes without compiler,
just for debugging...

-Added my name to the ToDo file under documentation
-Glossed the oof files
-Minor glossary additions elsewhere
-Another set of changes to gforth.ds; mainly the addition of material
 to the introductory chapter. Also, re-organised stuff in the oof
 sections and made a typo pass over a few other bits.

New "docclean" target for makefile (removes glossary dependencies when
rebuilding documentation). Changes to .fs files and prim are restricted
to glossary (\G) additions for the documentation; this has necessitated
the addition of new white-space in places to stop the \G stuff from
obscuring the code. Many additions to doc/gforth.ds - new sections
added, a few things moved and some sections re-written slightly. There
are a set of things to tidy up before this rev. is suitable for
release, and those will be my highest priority. I have also used
"@comment TODO" to highlight other sections I plan to work on, and
added a set of comments at the start to indicate other things I plan
to modify in the medium-term.

Fixed DOES> see bug

added exception
commented out global-map definitions in gforth.el
fixed see-code bug, improved isprim?
some ifdefs in arch/m68k/machine.h for AmigaOS (contributed by Jorge Acereda)

See got some more bug fixes.
Quick changes to let all cross-compile, and fit into ec-version.
These files are still on my ToDo list, changes are not complete now.

WORDS and SEE now now respect the terminal size.
a lot of reordering in the Makefile, approaching the GNU standards.

Added a generator for forth primitives
Cleaned up some minor errors
Changed names of local access (was cell size dependent)
Where is "getopt.h"???!? Added tiny workaround. Where is getopt_long?
