When sim_brk_type_desc isn't populated, the matching breakpoint switches
and matching address are displayed. Fix to use the optional VM provided
address formatting function sim_vm_sprint_addr.
Also extended the optional VM supplied routines to include sim_vm_sprint_addr.
Simulators which provide sim_vm_fprint_addr should also provide
sim_vm_sprint_addr with sim_vm_fprint_addr reworked to leverage
sim_vm_sprint_addr internally. sim_vm_sprint_addr is currently only used by
sim_brk_message() which is an API which a simulator may choose to use if
it supports multiple breakpoint types,
- Add detailed error message info while parsing breakpoint commands
- Properly limit breakpoint class values to reflect available mask bits
- Declare globally sim_brk_npc since it is a documented API
- Revise simh_breakpoints.doc to reflect current behavior
- Previous changes made to support 32V's 60HZ clock tick introduced changes
which didn't properly handle increments and interrupt generation while single
stepping the timer.
- The icr_rd routine returned an incorrect value when interpolation was
necessary due to a missing cast when converting from double to uint32.
- Properly start the timer from the current state of the interval count register
when the timer was previously stopped.
Reworked all priority adjustment code to leverage a new
sim_os_set_thread_priority API which is coded to use pthreads or OS
priority adjustment APIs as necessary.
The new RUN/GO command syntax supports a stop criteria.
There are two forms of stop criteria:
1) A normal breakpoint (which exists only until it is encountered)
2) A user specified output string is emitted by the simulated system.
Command syntax is:
RUN|GO {START-PC-VALUE} {UNTIL breakpoint|"output-string"}
Multiple rules with the same match string are processed in the order the EXPECT
commands are entered. NOEXPECT will remove all pending EXPECT rules which
have the match string provided on the NOEXPECT line.
These changes facilitate more robust parameter type checking and helps
to identify unexpected coding errors.
Most simulators can now also be compiled with a C++ compiler without
warnings.
Additionally, these changes have also been configured to facilitate easier
backporting of simulator and device simulation modules to run under the
simh v3.9+ SCP framework.
The SHOW FEATURES will enumerate all devices in a simulator and for each of
them display the device specific description if one is available.
This change allows the description to be optionally visible for a single device
displayed with SHOW DEVICE.
The previous change in handling or SCPE_EXPECT transformed it to SCPE_OK
to avoid unexpected exiting or condition trapping. This didn't allow the
SCPE_EXPECT reason to be display if verbose mode was on.
The exploit purpose of an EXPECT command is to return control to the SCP
interpreter when data output matches the expect condition; This will then
allow either related action commands specified on the EXCEPT command to
be performed or subsequent commands in the running command file.
Prior logic attempted to load the desired file from the current default directory and if that failed wrote the in memory boot code image to the desired file and then retried the desired load..
A user can still explicitly load a ROM image with a "LOAD -R romfile.bin" command prior to a BOOT attempt if they want to test or otherwise run with a different ROM.
