bal d07b17ca5c The routine con_float now generates a dummy floating point constant 
and gives a warning, instead of generating a fatal error + abort.
 1984-11-06 12:50:21 +00:00
bal 58c679c94c Patterns for floating point instruction and for LFR 8 and RET 8 added. 
Each such instruction now results in a call to a library routine.
At present, all these routines generate an Illegal EM Instruction trap,
but anyone wishing to implement floating point for the 6502 can
do so without changing the back end table.
 1984-11-06 12:47:26 +00:00
em e2e78ccd0a The line with the user message for failure missed the call to echo. 1984-11-06 10:02:25 +00:00

installs tail_em rather than comparing it

keie 2976b590af The flag -LIB was missing in the call to the shell-procedure 
compmodule. Thus the generated libraries could not be effectively
used by our assembler/linker.
 1984-11-05 11:37:23 +00:00
bal a837112d99 Negation of negative operand with inc/dec added in certain cases. 
Don't know effect for sure, author has left.
Added rcsid.

 1984-10-08 14:09:28 +00:00
bal 46dc90f366 bug fixed: generate "add.l #65536,a1" rather than "lea 65536(a1),a1".

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

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.
