AltairZ80 uses 0 for the VM-specific HLT instruction stop code.
SCP defines SCPE_OK as 0.
SCP uses 0 to mean all errors ("ON ERROR").
The command "ON 0" will generate "%SIM-ERROR: Invalid argument: 0".
This PR changes the HALT stop code from 0 to 5.
* Add support for 8259 interrupt controller.
* Add support for Cromemco and Tarbell Monitor ROMs.
* To allow port 0xFE to be used by the simh_dev.
* Use the CPU's SR instead of a SCP300F-specific one.
* 9513 RTC support.
When converting to a newer Visual Studio version, a new solution file is
created named simh-'vsversion'.sln so that we don't modify any files
managed by git. The resulting converted solution file will be automatically
used when build_vstudio.bat is subsequently run and that solution can be
opened directly by the Visual Studio IDE.
- Pre-Pre-Build-Event.cmd now dynamically determines the available
compiler version along with any alternate toolset which may be part
of the build environment and makes the appropriate windows-build
library support available for linking.
- build_vstudio.bat now supports VS2022 and will dynamically adjust
the converted VS2008 project files to leverage any available XP build
support which might be installed so that the generated executables
will support all versions of Windows from XP onward. The VS2008
generated executables automatically support all versions of Windows
from XP onward.
Visual Studio defaults to disable the ability to redirect stdout and stderr
for the cl.exe program during a build. This change allows us to capture,
record and display the compiler version.
On an unfettered system, the sel32 test completes after some 588 million
instructions. On a slow host system, the system clock tick processing will
add to the total instructions executed. Increase the limit to 750 million
instructions.
- Validation was incorrect for large numbers
- Polish help text for DO command variable insertion
- Polish help text for file name part expansion
- Add SIM_RUNTIME (number of instructions/cycles executed)
- Add SIM_RUNTIME_UNITS (instructions or cycles)
The previous implementation of sim_load was riddled with little errors.
This change fixes those errors, improves user feedback, and limits the
allowable flags to '-r' and '-o'.
- Change grouping of simulators built in each job to be in
alphabetical order so reviewing failed or active github actions
are more easily identified in the log information.
