Make generate.py resuable outside of open-simh, as suggested and
motivated by Richard Cornwell's simulator repository.
- Make the "experimental" rule optional. Do not generate a Python
"KeyError" if the rule is missing.
- Add documentation on how to use the CMake infrastructure outside
of open-simh: Customize the packaging.py script, season to taste.
- Update the KA10 simulator customization, moving it to its own
Python script, simgen/pdp10_simulator.py. Preparatory move that
anticipates additional frontpanel and display options.
- generate.py option "--skip-orphans": Skip the orphaned simulator
check (i.e., don't cross-reference the simulators in packaging.py
with what was scraped from the makefile.)
- Add "TEST_ARGS" argument to CMake's add_simulator function so that the
IBM 1130 simulator can pass to "-g" on the command line to disable the
GUI when running RegisterSanityCheck, i.e.:
ibm1130 RegisterSanityCheck -g
This fixes an edge case Heisenbug encountered during Github CI/CD
tests where ibm1130 appears to hang indefinitely on the Windows
runners.
The cause is the GUI's Pump() thread function being prematurely
terminated before all GUI resources are acquired. The net result is an
infinite loop in the MS C runtime trying to exit the process with
unstable internal state. (Separate patch: synchronization across main
and Pump() threads to ensure resource acquisition completes.)
This issue never shows up on non-Windows platforms or the SIMH makefile.
- cmake/generator.py, cmake/simgen: Add a "test_args" keyword argument
to the BasicSimulator constructor that holds the tests argument
parameter emitted as the "TEST_ARGS" argument to a simulator's
add_simulator(). Ensure that the IBM 1130 emits 'TEST_ARG "-g"' in its
add_simulator().
- scp.c: reset_all_p() adds 'P' to the existing switches, versus saving
sim_switches and ONLY setting the 'P' power-up reset switch. Net effect
is that the IBM 1130 simulator actually sees the 'G' flag that inhibits
the GUI during the console device reset.
Issue #294: "apple silicon build problem(s?)": If the "--flavor/-f" flag
is not specified on the command line, then complain loudly, print help
and exit. The script used to default to "Unix Makefiles".
Updates:
- Add missing "-DHAVE_LIBPNG" compiler command line define when the PNG
library is detected/present for screen capture support.
- Add "clang64" to the list of MinGW64 platforms for which the
.travis/deps.sh script can install build dependencies.
- Add PThread4W_FOUND to the condition that sets async I/O for Win32
when using vcpkg for build dependencies.
- Add vs2022-x64, vs2019-x64 and vs2017-x64 build environments to
build 64-bit Windows executables.
- Use simulator AIO only where needed by the simulator (i.e., the
simulator calls/uses AIO_CHECK_EVENT in sim_instr())
- Add "USES_AIO" flag to add_simulator() to mark a simulator that
acutally uses asynchronous I/O.
- Build "_aio" SIMH core library variants that have AIO turned on,
link with the "_aio" variant when a simulator sets USES_AIO.
- Emit a warning message when WITH_ASYNC is False (CMake configuration
option) to notify the user/developer that some functionality will be
crippled.
Affected simulator builds: 3b2 family, PDP-6, PDP-11, VAX family,
IMLAC and TT2500. The makefile and cmake/generate.py also updated
to remain in sync with CMake.
N.B.: Simulators still link with the underlying platform's threading
library. SEL32 requires pthreads or equivalent threading library,
independent of AIO.
- cmake/cmake-builder.sh
- New "--no-aio" flag: Build simulators without async I/O.
- New "--no-aio-intrinsics" flag: Don't build async I/O using compiler
compare-exchange, atomic load intrinsics.
- cmake/cmake-builder.ps1
- New "-noaio" flag: Build simulators without async I/O.
- New "-noaiointrinsics" flag: Don't build async I/O using compiler
compare-exchange, atomic load intrinsics.
CMake 3.28.1 INTERFACE_LINK_LIBRARIES behavior change: The file name
must now be an absolute path. Relative paths no longer accepted.
Internally, SIMH enforces this if CMAKE_VERSION >= 3.19, when REAL_PATH
was first implemented.
* CMake build infrastructure
The squashed commit that builds and packages releases for the SIMH
simulator suite with CMake, version 3.14 or newer.
