Re: SMOKING CLOVER (Color Tv)

[Alfred M. Szmidt]

I think we should reduce command line options and shove as much stuff
into usim.ini.  I was looking at the current ones, and they do seem
... seem sensible.

Idle / performance slider, I'm not sure what the purpose would be
... normally you run usim for a long time, and such a configuration
would be more or less permanent?


Just brain dump here, this is our current list:

  -a            enable Color TV
  -b            disable auto run from boot (usim will not automatically run 
after boot)
  -c FILE       configuration file (default: usim.ini)
  -d            dump all PC history of state on halt
  -D            like -d, but verbose
  -g X,Y[,DISP] set window position to X,Y overriding the config (decimal 
integers)
  -h            display this help message
  -k PORT       lashup target port to connect to the debuggee
  -p            disable auto power off (usim will not exit when stopped)
  -w [FILE]     warm boot (from usim:state_filename or FILE)
  -f LC         DISABLED: enable *full* tracing after lc reaches LC (decimal 
integer)
  -l LC         DISABLED: dump state whenever lc reaches LC (decimal integer)
  -t VMEM       DISABLED: add a read/write trace for virtual memory location 
VMEM (decimal integer)
  -u npc        DISABLED: dump state whenever the microcode pc reaches npc 
(decimal integer)

I'd suggest we reorganize it slightly:

  -c FILE       configuration file (default: usim.ini)
  -g X,Y[,DISP] set window position to X,Y overriding the config (decimal 
integers)

  -a            enable Color TV

  -w [FILE]     warm boot (from usim:state_filename or FILE)
  -b            disable auto run from boot (usim will not automatically run 
after boot)
  -p            disable auto power off (usim will not exit when stopped)
  -k PORT       lashup target port to connect to the debuggee

  -d            dump all PC history of state on halt
  -D            like -d, but verbose

  -f LC         DISABLED: enable *full* tracing after lc reaches LC (decimal 
integer)
  -l LC         DISABLED: dump state whenever lc reaches LC (decimal integer)
  -t VMEM       DISABLED: add a read/write trace for virtual memory location 
VMEM (decimal integer)
  -u npc        DISABLED: dump state whenever the microcode pc reaches npc 
(decimal integer)

  -h            display this help message

Would it make sense to delete -g and make it possible to set that via
usim.ini?  Just an idea, I think having -g is useful, and many
programs support it anyway.

I'd also maybe suggest that since by default we dump _some_ history,
we delete -D or make -d into -D.  -d is still very useful for early
broken stuff, if it prints more stuff it doesn't do much harm.

Regarding -f/-l/-t/-u -- are we (you?) using those?  If they are
disabled, maybe just elide them from usage() entierly.  I see use for
those, so very on the fence.
