I have working inline assembly code for copybytetoaux()
. However there is still a bug lurking in the if
/else
/endif
handling somewhere.
from eightball.
I have fixed the issue that was causing bad code generation in some cases when storing bytecode to extended memory on Apple //e enhanced. The problem seemed to be caused by failure to advance rtPC
when writing the final null of the string argument to a PRMSG
VM instruction. However I can't see what is different in the extended memory vs the normal memory case. Even though this seems to be fixed, the fix remains a bit mysterious and is commented in the code as a TODO.
This fix, plus the inline assembly version of copybytetoaux()
is enough to get this feature working well enough so I can compile both unittest.8b
and tetris.8b
.

v0.77 pushed.
