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

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 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.

Instead of hardcoded -lelf/-ldwarf use cmake modules FindLibElf/-Dwarf
and link the found libraries accordingly. This enables the user to have those
libs in arbitrary locations and link them from there.

With this change, x86 special-purpose registers (e.g., EFLAGS) get the
same register ID in both 32 bit and 64 bit configurations.
Change-Id: I69db9397481414f99ca05ecb0ea9dc8ab7d989c9
This bug mapped EFLAGS to the same Fail* register ID as R9 on x86_64. This
probably has not had consequences yet, as most FailBochs users use 32-bit
code.
Change-Id: I00a680675bb9e73c2781276f3ef651162c8e4445
This change limits fault injection to general-purpose registers, instead of
relying on the LLVM/Fail* bridge to only recognize the status register
(EFLAGS on x86) and general-purpose registers. Since this bridge just
learned to translate x86's control and segment registers, and these
registers need special handling for fault injection (def/use pruning does
not work here), only import register accesses from the RT_GP subset.
Status register and instruction pointer injection remain functional, and
import-trace now should work architecture independently.

There are instruction in the real world, that seem to read more than 8 bytes.
Therefore we cap the accesses memory to 8 and don't abort with an assertion.

Internal LLVM register IDs can and did change between LLVM versions.
These magic integers are replaced by iterating over all LLVM registers
and mapping them to FAIL* registers by name.
As this iteration requires a LLVM object created from a binary, a static
convenience function is added to LLVMtoFailTranslator which creates a
translator given the binary filename. Building this functionality inside
libfail-llvmdisassembler prevents experiments from needing to add LLVM
includes and library definitions.
