This change introduces a fake iobus device into gem5 to prevent
it from crashing on bogus I/O memory accesses.

Since commit c142818, DatabaseCampaignMessage.proto is generated into
the binary directory, which must be announced to the protobuf
compiler.

Enabling both CONFIG_FAST_BREAKPOINTS / CONFIG_FAST_WATCHPOINTS and
CONFIG_EVENT_BREAKPOINTS / CONFIG_EVENT_BREAKPOINTS_RANGE /
CONFIG_EVENT_MEMREAD / CONFIG_EVENT_MEMWRITE led to an (unnecessary)
include cycle.

This change allows to use the generic-tracing experiment with a
manually specified start/stop address. This is necessary to use it
with more complex systems that aren't booted from a single ELF file,
such as Fiasco.OC.

This fixes a gcc 4.7 warning: comparison between signed and unsigned
integer expressions [-Wsign-compare].

BochsController::getTimerTicksPerSecond() only works reliably when the
simulation is already running (e.g., after a restore()). This broke
timeout conditions for the very first experiment in a FailBochs instance.

This change fixes another Bochs crash in the floppy controller,
triggered by one out of 670 million experiments in my current
campaign.

This change makes the DatabaseCampaign load all pilot_ids from the result
table in memory instead of LEFT JOINing them for each variant. This vastly
improves campaign speed (possibly making commit 5567c59 superfluous) at the
cost of slightly increased startup time for half-completed (large)
campaigns.
By exploiting the generally continuous nature of pilot IDs and using a
boost::icl::interval_map, the additional memory requirements are
insignificant.

When no variants matching the command line parameters were found, the
campaign printed an uninitialized sent_pilots count.

The fix for tools/convert-trace/Gem5Converter.cc repairs a real issue
which caused a runtime warning to never be displayed.

This change updates the documentation on how to manually build LLVM
3.3 or 3.4, and removes the forced -fno-rtti compiler flag from
util/llvmdisassembler/: The flag breaks compilation with (not yet
released) AspectC++ 2.0, which complains about dynamic_cast (used in
some active aspect headers that should not affect llvmdisassembler at
all) being unusable with -fno-rtti. It's probably not a good idea to
compile only a part of Fail* with -fno-rtti anyways.
Note that the Debian and Ubuntu LLVM packages are built with
REQUIRES_RTTI=1, too.

This crippled version of the weather-monitor experiment is not needed
anymore, as gem5's restore() works now.

This change extends import-trace's help functionality for importers,
adds the ?-operator to option "-i" and refactors main.cc a little.
The extensions are "doing something useful with the AliasedRegistry"
and are merely listings of all importers' prime aliases.
Change-Id: I7bb184fc45dd9f90664e37455edfccc704d99ef1
This change implements a generic registry in order to clean up import-trace's
code - it's possible (and reasonable) to use the registry for pruners as well.
Importer now extends AliasedRegisterable; all importers have been adapted
to suit the interface/abstract methods.
Each AliasedRegisterable should have at least one alias (the class' name
is a sensible choice) but can have several. The first specified alias is
the class' prime alias which can be used e.g. to list all registered objects.

-Wunused-local-typedefs is included in -Wall since GCC 4.8, and generates a
flood of "typedef '...' locally defined but not used" warnings in
ac++-1.2-generated code.

The libiberty headers moved from /usr/include (and a part of binutils-dev)
to /usr/include/libiberty (libiberty-dev) between Ubuntu 13.10 and 14.04,
which made a proper cmake search module necessary. Searching still
continues working well on Debian 7.

This change adds an optional command line argument "--database-option-file",
which can be used to override the default database configuration file ~/.my.cnf

Somehow, while iterating symbols in a section, it can happen that the last
symbol start address is equal to the section size, which means it is beyond
the section end.
In this case the LLVM getInstruction() method does not return a failure, but a
zero-size instruction, resulting in an infinite loop.
Now, if beyond section limits, the iteration is aborted.
Additionally, an assertion checks for disassembled zero-size instructions.

As the eCos kernel tests do not sufficiently check for failures, a
(compared to the golden run) measurably *reduced* simulation time can be
used as an indication for SDC.
