Avoid the potential by properly leveraging the range that the
recursive mutex which already properly serializes separate activities
to the debug log file.
- Add HELP language for SET CONSOLE DBGSIGNAL|NODBGSIGNAL.
- Remove obsolete sim_os_poll_kbd_ready platform specific routines
which were only used with the never functional asynchronous TMXR
code which has been otherwise removed everywhere else.
- Cleanup DBGSIGNAL related code comments
-
Removed previously added DEPOSIT ALL 0 in precalibrate routine.
That DEPOSIT was added to explicitly restore memory to 0's at simulator
startup, but the several second cost of executing that slowed down
startup of any simulator which had precalibration support. Anyone who
explicitly cares to have zeroed memory on startup should include such a
command in their own simulator configuration.
Allow: n execute n instructions/cycles per second
nK execute n thousand instructions/cycles per second
nM execute n million instructions/cycles per second
n% occupy x percent of the host CPU capacity
n/t sleep for t milliseconds after executing x
instructions/cycles
n{K|M}/t sleep for t milliseconds after executing x
thousand or million instructions/cycles
1 - Summarize repeated memory contents so that the memory range with a
given value only emits 2 lines of output
2 - Allow ^C (SIGINT) to potentially abort long running EXAMINE output
- Make sure that asynchronous mode can't be changed if devices using
sim_ether are already attached.
- Add missing DEV_ETHER type flag for the only sim_ether using device
that didn't already have it.
- Without regard to whether the circular buffer data is otherwise in
use while instructions are executing.
- When a circular debug buffer is in use, avoid writing out the contents
with the periodic open file flushes and only do so on returns to the
sim> prompt and when debug is closed
B. Scott Michel's run of clang memory sanitizer potentially identified
that when a substring doesn't match the returned array offsets would
be -1.
This commit handles that potential and sets the respective substring as
an empty string.
- Behave well when NOCALIBRATE mode is enabled after some instruction
execution already happened.
- Properly detect the reliable calibrated clock or use the internal one.
