Peter Evans c53c7bfd1d Add function to return true if an instruction would write to memory 2018-04-21 23:15:48 -05:00
Peter Evans 37f9e627ba Change from last_opcode/last_operand to opcode/operand 
This change also makes it so that those values are set once they are
known, rather than only at the end of the execute function.

Peter Evans b5fef760b8 Remove the map_mach abstraction in favor of vm_di 2018-04-15 22:30:57 -05:00
Peter Evans 8e810e724f Add addr_mode field, rely upon it vs. the opcode 
This makes testing _slightly_ easier, because now the handlers require a
type of state in the cpu vs. a specific opcode state in the segment that
we execute from. (The latter being just more complex to work with and
require in testing.)

Peter Evans 5730e5e446 Add explicit definition of unused bit 2018-04-13 16:15:12 -05:00
Peter Evans 6e77e99813 Add ability to debug separate from pausing 
Also, pausing just pauses now; no debugger prompt is shown. ALT+P
toggles pausing, so just hit it again to unpause. Also, when things are
paused, you can perform other keyboard events (like quitting).

Peter Evans a913668c02 Missing some reorg changes; move reflect into event, debug 2018-04-07 00:26:31 -05:00
Peter Evans 74aafb0d01 Reorganizing files into directories 2018-04-06 20:27:47 -05:00
Peter Evans 281544bf43 Avoid polling for events until we're ready for a frame redraw 
This change drastically cuts the number of times we poll for events, and
consequently drastically speeds up the number of frames we can draw
within any given span of time.

In other words, we go from "this barely moves as fast as the actual
Apple II" to "holy shit this moves so fast".

Peter Evans d2047457e9 Use log_crit() instead of log_critical() 
This change also removes the former log_critical and log_error macros.
 2018-03-29 21:45:25 -05:00

emp is a much older name for the program

Peter Evans 64afcb2040 Rewrite phaser to use state transitions, whole phase states 
By whole phase states, I mean we no longer track if more than one phase
is active.
 2018-03-23 19:41:01 -05:00
Peter Evans 2870bc03bc Remove option flags; remove unnecessary --flash option 2018-03-21 15:26:58 -05:00
Peter Evans 5ea10d8a98 We track steps in quarter tracks, so double the max 2018-03-20 15:07:55 -05:00
Peter Evans 474104085c Reorganize encoded sizes/routines to align with reference nibble output 
(This is comparing to the output that we see from dsk2nib.)

Peter Evans 9562dd19ce Rewrite dd to use phases and half-track steps 
Phases will yet be the death of me. THE DEATH OF ME.

Peter Evans b239cac239 Add dblock command to disassemble blocks of code 2018-03-01 19:31:56 -06:00
Peter Evans f8bda4ebd3 Remove modify_status() function 
Also rewrite tests to use macros
 2018-02-28 21:40:52 -06:00
Peter Evans 49199eac84 Rewrite status checks with macros 
This also forces the result of operations to be considered purely as
8-bit results in _some_ cases, but not in others. We were missing some
times when an overflow is the expected behavior; because SET_RESULT()
and mos6502_modify_status() use ints, this overflow was not properly
observed.
