Adjust the RUNLIMIT to specify instructions instead of wall clock time.
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.
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'.
MASM generates REP CS:MOVSW as:
REP
CS:
MOVSW
The Seattle Computer Products 8086 assembler allows the segment override
as a discrete opcode. This means that:
CS:
REP
MOVSW
is also possible, and in fact used in the SCP Monitor v1.6.
The i86 emulator was clearing the override flags when REPE/REPNE,
is encountered, which causes the segment override to be lost.
Verifying the behavior of a real 80286 processor in an IBM PC/AT
(5170) using MS-DOS 6.22 DEBUG shows that both instruction sequences
yield the desired segment override.
The GCC documentation explicitly says not to use that option
when -flto is used, and since that is the only place where
the makefile was using it, remove it to conform to the
documented rules.
- Configure run on push and pull requests
- Use new macos and ubuntu OS images
- Add missing simulators from the build list
- Add potential LTO option for makefile builds
When building compiler optimized binaries with the gcc or clang compilers,
invoking GNU make with LTO=1 on the command line will cause the build
to use Link Time Optimization to maximally optimize the results.
Link Time Optimization can report errors which aren't otherwise detected
and will also take significantly longer to complete.
This change allows CI builds to fail without detailed viewing of build output
for gcc and clang builds (all modern compilers). Thus forcing PR submitters
to find these problems before PRs are merged. This is done by compiling
with -Werror for these compilers.
We don't know how to do this for other compilers which may be able to use
the makefile, so warnings there will still proceed to build successfully.
* AltairZ80: SS1: Fix disable after reset.
The CompuPro System Support 1 could not be disabled after enabled and
used due to timers causing it to be busy. Reset properly so that "set
ss1 disabled" works after reset.
* AltairZ80: wd179x: Properly reset 179x state.
* AltairZ80: M68K: Fix compile with VS2008.
* Musashi: Fix compilation with Visual Studio 2008.
* AltairZ80: M68K: Resolve warnings in softfloat.
* AltairZ80: Add headers to .vcproj
* VIDEO: Fix bug: vid_ready can be used uninitialized.
* VIDEO: Not all events come with a valid windowID.
* PDP11: Fix NG SET TYPE.
The sense of MATCH_CMD is reversed.
* display: Fix bug in NG display controller.
There should be a separate state for each of the eight displays.
* display: Symbolic constant for number of displays.
