bal 0db1db10b8 Bug fixed: cg generated instructions like "and.l #2,a4", which are 
not allowed on the 68000.
The condition "inreg($...) < 2" is added to every EM-pattern that
accesses local non-register variables. So the ordering of the
patterns for regvar/non-regvar is no longer important.

    every action.
 1984-10-08 14:09:28 +00:00
bal 46dc90f366 bug fixed: generate "add.l #65536,a1" rather than "lea 65536(a1),a1". 
The latter form is only generated for constants that fit in a word.

sater 2bf16c5b2f Variable nregvars had a name clash with the array nregvar[] in the 
file tables.c. That was different in the 8'th character (!"#$%&'()_).
These variables should actually be static.
 1984-08-23 17:07:53 +00:00
sater 5689e6ab64 Increased the amount of information passed through error routines 
to printf. The routine badassert, running on a 2/4 machine lost it's
last argument on the way.
Anyone know of a better way to solve this problem?

fakestack)
 1984-07-30 11:16:41 +00:00
bal 233b4aeee4 patterns added to generate autoincrement and to generate

Now if someone uses them he will hear that it doesn't work.
That must be better then giving him code that probably won't work.
All these patterns had to do with things like adf without an argument
and things like that.
