hellwig 640f5436cc Bugfix for regression-test experiment 
The output of regression-test was cut off. The problem was solved with
a flush before exiting.

adrian 1ce2cd96be regression-test fixes: use new register access syntax 
The golden-run image of the regression test needs to be updated in order to cope with the bugfix for breakpoint events in rep-instructions.

adrian 125914a305 BochsRegister.hpp and BochsRegisterIDs.hpp not needed anymore 
The includes of these headers have already been removed from the experiments. In the current code, the content of the header BochsRegister.hpp is rather simply copied to x86/Architecture.hpp. It is therefore necessary to revisit the code soon (especially the FIXME related to register IDs).

Another problem is that there is no generalization of register IDs. Thus, all experiments are currently specific to a concrete architecture (which is not desired).

hsc dfe4a5d4c0 ecos: split campaign into job producer and consumer 
When we want to use a bounded job queue, job producer and job consumer must
run in different threads in order not to deadlock the campaign.  Ideally
this functionality moves to the CampaignManager later (including the
retrieval of existing experiment results and storing new results).

hsc 35026de2d8 ecos: use multiple intermediate states to speed up experiments (disabled) 
This modification creates and uses multiple intermediate snapshot states
(one every 1,000,000 instructions) to fast-forward to the FI site.
Unfortunately this doesn't work yet; the trace seems to change in many (not
all!) cases we do this.  One possible cause could be an incorrect
(off-by-one or alike?) restoration of the serial device timers, and
therefore an earlier/later transition to "output buffer empty", resulting
in eCos' serial putc function needing a different amount of polling loop
iterations.  Needs more investigation.

hsc a0e6ddd519 ecos: fault-space cutoff specific for this campaign 
For the eCos kernel test campaign we define a relatively "special" metric
to compare FI results from different applications:  Instead of aligning
the fault-space dimensions (e.g., by artificially adding "don't care" space
to the right for shorter application variants), we only keep the data
address axis constant.  The rationale behind this is that -- despite the
benchmark applications' run-to-completion behavior -- an operating system's
scheduler usually runs ad infinitum, and that we therefore can extrapolate
from a short application run to any longer period.

In essence, this means we use a failure/experiment-length quotient (ignoring
the Y axis for simplicity, as it is constant in size) to compare
application variants, instead of an absolute failure count.  One important
side effect is that we do not punish any application slowdown with this
metric.  (And simply prolongating non-susceptible program sections with,
e.g., NOPs, seemingly "improves" fault tolerance.)
