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.
As discussed in #1034
The new REG_DEPOSIT register flag bit indicates that updates to a
REGister with this flag specified will invoke the sim_vm_reg_update
routine after the data has been updated.
This avoids a potential invalid pointer dereference when formatting
the return value from sim_instr() if it is < SCPE_BASE but greater
than the previously defined static array size.sizeof
Update simh.doc to reflect this generic change.
The paradigm of using a "weak" linker reference to find what was
previously the vm_init_routine() doesn't work reliably on all compile
environments supported by the simulators. This has been reported
in #794 and it came up again in #862. This change assures that
it will not come up again AND it reliably solves the problem with
Visual Studio compilers (and linker) that randomly chooses whether
to have the desired effect or not.
Of the 82 simulators which are currently part of simh, only these
three used the sim_vm_init() interface, so removing it had relatively
minor impact.
- Make all PDP11, VAX RP and RQ devices autosizing behave similarly
- Generalize the attach help to be specific to the device/system being
attached
- Remove the sim_disk_pdp10_* calls which weren't correct or needed
since sim_disk_attach_ex provides sector size which is used correctly
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.
The original approach had separate parallel arrays for each relevant
state variable for each calibrated timer. That worked when there were
only a few state variables, the state info for a timer belongs in a
structure.
- Force the detection point of a tape structure error to be the logical EOM
on the tape.
- Enable SIGINT abort of a possibly long running validation scan
- Add -L detail record structure option at ATTACH time
- Add extra garbage at end of generated test data files
Backed out commit 484889ea5a since the overflow of the timespec tv_nsec
field was the real cause of the problem. No need for an extra mutex.
As reported in #595
It seems that the prior use of sim_asynch_lock RECURSIVE mutex could
cause a pthread_cond_timedwait() failure with EINVAL returned.
As discussed in #595
Newest Win32 include files changed the include file order as compared to the
Microsoft MS compilers.
This is arguably a bug in the MinGW codebase, but working around it is too trivial
to complain about.
