George Koehler 0131ca4d46 Delete 689 undead files.
These files "magically reappeared" after the conversion from CVS to
Mercurial.  The old CVS repository deleted these files but did not
record *when* it deleted these files.  The conversion resurrected these
files because they have no history of deletion.  These files were
probably deleted before year 1995.  The CVS repository begins to record
deletions around 1995.

These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted.  There is no way to fix
this, because the CVS repository provides no dates of deletion.

The file 'table' in this directory contains a back end table for the
MC68020 processor as well as one for the MC68000. Both tables use 2 or 4 bytes
for words and 4 bytes for pointers. The table must be preprocessed first
by the C preprocessor.
The file "whichone.h" specifies which code generator is generated:
it #defines either TBL68000 or TBL86020, and it defines WORD_SIZE to either
2 or 4.
The m68k4(TBL68000) cg can very well be used for the MC68010 processor,
for it makes rather efficient use of the 68010 loop mode.

The mach.[ch] files are also suitable for both the m68020 and the m68k[24].
