Eliminate extra gotos in common branch tail code (#528 )

The implementation of various JUMP opcodes tried to use a common tail that did a POP and branched to the next opcode. While the extra gotos probably aren't harmful, neither are they beneficial to code size or speed.

-We are developing on FreeBSD, Linux, macOS, and Solaris currently

+Development has been primarily on macOS, FreeBSD, and Linux, with testing on Solaris and Windows.

+### Building with CMake
+We provide a `CMakeLists.txt` which provides mostly matching build capabilities to the `make` setup.
+CMake options are provided to control the configuration of the Maiko executables:
+* MAIKO\_DISPLAY\_SDL: [OFF], 2, 3 - selects display subsystem SDL of version specified
+* MAIKO\_DISPLAY\_X11: [ON], OFF - selects X11 display subsystem
+* MAIKO\_NETWORK\_TYPE: [NONE], SUN\_DLPI, SUN\_NIT, NETHUB - network subsystem access
+* MAIKO_RELEASE: [351], various - see `maiko/inc/version.h`
+
+While SDL3 is selectable, the Maiko code has not yet been updated to work with the SDL3 API.

 ### Building For macOS

-* Running on macOS requires an X server, and building on a Mac requires X client libraries.
+* Building/running on macOS requires either an X server and X client libraries or the SDL2 library.
 An X-server for macOS (and X11 client libraries) can be freely obtained at https://www.xquartz.org/releases
-
-### Building for Windows 10
-
-Windows 10 currently requires "Docker for Desktop" or WSL2 and a (Windows X-server).
-See [Medley's README](https://github.com/Interlisp/medley/blob/master/README.md) for more.

Author	SHA1	Message	Date
Nick Briggs	511a1b523e	Eliminate extra gotos in common branch tail code (#528 ) The implementation of various JUMP opcodes tried to use a common tail that did a POP and branched to the next opcode. While the extra gotos probably aren't harmful, neither are they beneficial to code size or speed.	2025-01-30 11:07:29 -08:00
Frank Halasz	04f9905ca0	Fix MacOS SDL build in buildRelease github workflow (#527 ) * Update buildRelease workflow to use sdl2-2.30.11 on MacOS * In buildRelease workflow, update Macos build for SDL to use -DMAIKO_DISPLAY_SDL=2 instead of =ON	2025-01-29 08:51:47 -08:00
Nick Briggs	e61d0f2e6c	Correct {DSK} versioned file cache failures (#526 ) A missing check for the applicability of a versioned file cache caused loadups to fail in the case where the modification timestamp of a directory and its parent were identical, and the file being looked up had the same name (when lowercased) as the directory it was contained within. E.g., looking up TEDIT in library/tedit/ where the modification times of library and library/tedit were identical. The inode number of the directory containing the file must be the same as the inode number of the directory the cache was built from.	2025-01-26 18:38:25 -08:00
Nick Briggs	3c4d9f5393	Modifies LISPFINISH subr to use 2nd argument, if present, for exit status (#525 ) Redesign of exit status handling, instead of overloading the FAST flag of (LOGOUT fast), add an optional 2nd argument, EXITSTATUS. Retains compatability, with behavior unchanged, between new emulator and older sysouts which do not pass the second argument to LISPFINISH. Newer sysouts, which pass the 2nd argument, will continue to work with older emulators though will not get the exit status set.	2025-01-20 12:24:44 -08:00
Nick Briggs	31bb14b9d7	Modifies Lisp exit subr to permit passing an exit status code (#524 ) These changes add (LOGOUT <number>) to the traditional (LOGOUT) and (LOGOUT T) calls. If an integer <number> is provided it will be used as the exit status code, while NIL and T result in an EXIT_SUCCESS. If the argument passed is none of NIL, T, or a number, the exit status code will be a generic EXIT_FAILURE (typically 1). (LOGOUT) and (LOGOUT T) virtual memory behavior is unaffected. When a <number> is passed Lisp will exit without saving the virtual memory state, as is the case for (LOGOUT T), although this behavior is determined by Lisp rather than the Maiko emulator.	2025-01-16 09:57:01 -08:00
Nick Briggs	f23a43f1a0	Merge pull request #522 from Interlisp/nhb-dspbout-and-showdisplay Improves behavior of display subrs DSPBOUT and SHOWDISPLAY	2024-12-22 14:10:37 -08:00
Nick Briggs	e251f26816	Improves behavior of display subrs DSPBOUT and SHOWDISPLAY DSPBOUT is called to output a single character to the "BCPL display", which is the system text output rather than the bitmapped display. Under maiko, this is mapped to "stdout". Interlisp-D uses CR as the EOL character, but that is not appropriate for output to standard output so CR is translated to LF here. Standard output is buffered, but there is no indication of when the output should be flushed, so flush on every character, since this is a low frequency operation. SHOWDISPLAY is called to switch between the "BCPL display" and the bitmapped display. The current display subsystems are not hooked up to this subr, but this is a potential place to hook display size changes in the future, so the code is updated to indicate the parameters passed in and to set/reset the display initialization state variable.	2024-12-18 12:40:29 -08:00

This commit changes the command line timer option to "-timer" and adds "timer" to the options that are processed from the X11 resources.	2024-12-16 19:59:03 -08:00

Nick Briggs	55d8504060	Corrects interaction of BITMAPBIT with buffered display bitmap Two problems fixed: * only in the case of a software cursor is it necessary to check if the bit being altered is within the region of the display covered by the cursor, and if it is, the cursor must be hidden before operating on the screen bitmap * SDL as well as X requires modifications to the screen bitmap be flushed to the actual display.	2024-12-14 13:22:44 -08:00
Nick Briggs	ecdab720f2	Missing call to flush_display_lineregion() for SDL in PILOTBITBLT When the target for a PILOTBITBLT operation is the display bitmap, and the display bitmap is not memory-mapped from the actual display, the display subsystem needs to be notified to flush the Lisp display bitmap to the display so that changes are immediately visible. The mechanism was present for X11 displays but needed to be implemented for SDL displays.	2024-12-14 12:57:24 -08:00
