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.
See README-CMake.md for documentation.
Start of support for PiDP10 front panel.
Moved interrupt checking from check_irq_level to clear_interrupt.
Pending interrupts now saved in IOB_PI.
Cleanup of KL10 Timer interrupts.
Minor code cleanup.
Added KS10 support.
CPU Redid instruction decode to improve performance
Triple-I display cleanup.
Normalized end of line to DOS/Unix.
KL10 FE, Cleanup issues with TTY devices hanging simulator..
Fixed errors in RH20 device.
RP and TU drives more independent of RH controller.
Devices that do single character I/O could be attached to non seekable
host OS devices (tty, pipes, etc.) and thus shouldn't count on fseek()
and ftell(). These DEVICEs on these simulators do single character I/O
and easily can update their POS REGisters to reflect how much data has
been emitted. Changing such a REGister will have no useful effect
when attached to a non seekable file.
Historically this functionality was reimplemented within each
DEVICE simulator often with slightly different implementations
and inconsistencies. Solving this globally within SCP required
changes in many places, but should henceforth be reasonably
managed.
