These were possibly useful options when asynch support was being
added long ago. Async simulator I/O is quite stable and should always
be leveraged whenever pthreads is available.
make vax the primary build target and microvax3900 the copied result.
The microvax3900 binary name was added when all the different VAX
simulator models were add to simh and each was appropriately named
based on the system model name of each respective simulator.
The vax simulator name was the earliest vax implemented so a binary
of that name is produced for upward compatibility for existing users.
Producing the vax simulator and then copying it to microvax3900
produces equivalent results, but is easier to auto convert to cmake
build configuration files which then will generate a vax project
file when cmake is generating those.
If libpcreposix isn't available, we can't fall back to the local
regex.h since the default C runtime on Linux and OS/X implementations
of the regex functionality doesn't ever match regular expressions
with imbedded newlines.
Added BASE option to auxcpu to move memory region.
Fix errors in Card Reader/Card Punch translation and operation.
Fixed problems with ITS quantum timer.
Added support for System Concepts DC10 disk controller (Lars).
Fixed errors in Line Printer control codes.
Added support for Lines per page to LP10.
Fixed issues with 7 track tapes on TM10.
Updated user guides
This change adds support for the WE32106 Math Acceleration Unit (MAU).
The WE32106 is an IEEE-754 1985 compatible floating point math
acceleration unit that was an optional component on the 3B2/310 and
3B2/400.
The MAU is implemented using software floating point routines. As
always, there may be bugs, but the MAU currently passes extensive
floating point tests with exactly the same results as a real 3B2/400
equipped with a physical MAU, so I hope these are few.
- Recent changes in vax_watch.c changed the input parameter from a
physical address to a register address within the watch chip.
- vax630_sysdev.c called the older wtc_wr() with the new parameter,
but the length argument has been removed.
- The watch chip never starts as valid. Make it valid when the TODR is
attached (i.e. reflecting a connected battery).
- 64 bytes of bus addresses for the watch chip can sometimes be dispatched
to wtc_rd() and wtc_wr(). Make sure that reasonable memory is always
referenced for all potential accesses.
- restore vax8200 to makefile which got lost in a prior merge.
Windows 10 1803 or later NTFS filenames are set to be case-sensitive if the Windows Subsystem for Linux (WSL) feature is turned-on. This was causing a build under cygwin 3.0.1 to fail detecting the libpcap header and library locations in the ../windows-build/libpcap directory.
- OS X libpcreposix segfaults when a compiled regular expression is freed.
- Revise regular expression syntax used in VAX diagnostic scripts to avoid
Perl oriented extensions.
- Diagnostic execution happens as a normal part of the makefile build.
- Diagnostic execution can be suppressed by invoking make with TESTS=0
on the command line
- Diagnostic execution during build is produced in summary form.
- clang's list of optimization options makes no mention of strict-overflow
or no-strict-overflow, but it silently accepts -fno-strict-overflow and
in fact honors it.
