In the current configuration, OK_MARKER would be plotted in white
color and be indistinguishable from the background. Not plotting
these areas at all reduces output-file size. As a side effect, the
initial Y-axis zoom level (ymin, ymax) can change.

By default, the data-aggregator scripts create machine-readable,
tab-separated output. The optional "-t" switch (passed to the
internally used `mysql' command-line client) creates human-readable
table output instead.

This change additionally allows to create a resulttype/occurrences summary
over all benchmarks in the database, instead of specifying a single one.

Instead of using the address difference between two neighboring symbols as
an indication for the symbol's size, import the size as reported by
`nm -S'.
Additionally, this change fixes an off-by-one, which had the effect that
the last symbol in the list was not imported at all.

This change introduces a loose collection of scripts for
analysis/aggregation of FAIL*'s collected data.
It's going to be developed into a proper tool in the future.

This change adds the capability to import an ELF's symbols
into the database. The functionality is implemented via a
shell script and will be merged into "import-trace", when
it's being cleaned up sometime in the near future, but for
now this suffices.

This change adds detection of SDCs to GenericTracing and
GenericExperiment via Bochs's I/O port E9.

This change introduces the ability to inject burst faults to
the DatabaseCampaign/-Experiment and thus to all derived
campaigns/experiments.
Change-Id: I491d021ed3953562bd7c908e9de50d448bc8ef33
Up until now only generic-tracing had the feature to directly
pass an ELF file to the experiment. generic-experiment lacked
that functionality and resorted to using the $FAIL_ELF_PATH
environment variable.
This change introduces the "--elf-file" command line argument
to generic-experiment.

This change adds the faultspace-plotting scripts into FAIL*'s
tools/analysis/ folder and makes it CMake-configurable.

- Debian 8 does not provide libsvga1-dev anymore, so Bochs cannot be
built --with-svga (which is included in --with-all-libs).
- The latest AspectC++ nightlies should work without any
-D__NO_MATH_INLINES -D__STRICT_ANSI__ tricks.

ERIKA Enterprise is a OSEK conforming embedded RTOS. The supplied tracer
and experiment are similar to the cored-{tracing,tester} experiment, but
checks the integrity of the RTOS application in a different
manner. Stacks and stackpointers are located differently in ERIKA. This
experiment was used in RTAS'15 Hoffmann et al.

With the instantiate-indirect.ah method, we can choose between different
experiment flows at runtime. By this, we can combine tracing and actual
injection into one fail-client binary. A -Wf,--mode={tester,tracer}
switch does hand the control to different experiment flows.

For redoing the bench-coptermock-isorc experiment, we have to change the
timeout settings. We now use a soft timeout setting. A soft timeout is
resetted after each checkpoint event. If a hard timeout (2 seconds) is
reached although the soft timeout was resetted, we also abort the injection.
Change-Id: Ib7c2b1ad201641f47434a11d3273dde797e0012e
The checkpoint plugin is able to use dynamic values from within the
target to calculate its ranges. If the experiment injects faults within
those dynamic values, we will always get an digest error, even if it has
no influence on the outcome of the experiment or the integrity of the
data range.
Therefore, the plugin now provides a possiblity to cache those dynamic
values, before injecting them. This has to be done explicitly within the
experiment.

The instructions per second config option influences the point in time
of IRQ events and the simulator time values.

Sometimes the lines in an objdump can get very long. Therefore, we limit
the size of the field, which is put into the database, to the maximal
size of the opcode, instruction, and comment column.

The injection_instr_absolute can be NULL, if the trace was imported by
--faultspace-rightmargin R. The database-experiment then aborted the
injection, since a non present injection instruction is encoded as 0,
which is != 0.

This options performs a restore to the saved state of the machine immediately
after saving (default: off). This option is needed when the state is used by
other experiments that depend on the trace, which slighty differs without a
restore.

The generic-tracing experiment now supports logging of I/O port access to file.
Therefore, the serialoutput plugin needs to be included in the experiment
configuration. Without the --serial-file option specified, logging is disabled.

- Add missing iomanip header: Without this one, Fail/gem5 does not
compile.
- Remove unnecessary sal/bochs header: This seems to be a relic from
when the DatabaseExperiment was Bochs-specific.

This quick fix is necessary to let gem5 compile again. Instead of passing
NULL to onInterrupt(), a proper fix should pass the currently active
ConcreteCPU instance.

This change makes MemoryAccessListeners deliver linear addresses
instead of virtual ones deprived of their segment selector. Even in
modern operating systems, segment selectors are still used for, e.g.,
thread-local storage.
The hooks within MemAccess.ah could maybe be implemented in a simpler
and less fragile way using the BX_INSTR_LIN_ACCESS instrumentation
hook, but this needs more investigation.

* Removed all command-line options.
* Read all required information from *-traceinfo.txt file or kernel elf file.
* Record error_corrected (but only in the 'OK' case).
* Add support for multiple variants (similar to the ecos experiment).

Adds LIBUDIS86_PREFIX_DIR variable, to search for LIBUDIS86 in the
specified prefix. This makes it easier/possible to have libudis86 in
non-standard locations, for example when you don't have root.

Due to a bug (most likely a copy and paste issue), the detected-marker
group was defined to point to the "FAIL_marker"-set, which would be
redundant. This commit will correctly map it to the "DETECTED_marker"
group.

The color_assert_port symbol does not exist in all dOSEK variant,

invalid handler will trigger on INV_ADDR
