The LLVM Disassembler infrastructure can be used to analyze many kinds
of ELF Binaries. For every instruction the used and defined registers
is available as well as information about the instruction itself.

The DatabaseCampaign interacts with the MySQL tables that are created
by the import-trace and prune-trace tools. It does offer all
unfinished experiment pilots from the database to the
fail-clients. Those clients send back a (by the experiment) defined
protobuf message as a result. The custom protobuf message does have to
need the form:
import "DatabaseCampaignMessage.proto";
message ExperimentMsg {
required DatabaseCampaignMessage fsppilot = 1;
repeated group Result = 2 {
// custom fields
required int32 bitoffset = 1;
optional int32 result = 2;
}
}
The DatabaseCampaignMessage is the pilot identifier from the
database. For each of the repeated result entries a row in a table is
allocated. The structure of this table is constructed (by protobuf
reflection) from the description of the message. Each field in the
Result group becomes a column in the result table. For the given
example it would be:
CREATE TABLE result_ExperimentMessage(
pilot_id INT,
bitoffset INT NOT NULL,
result INT,
PRIMARY_KEY(pilot_id)
)

The import tool does support the following import strategies:
- BasicImporter: generates def-use equivalence classes for read and
write memory accesses
- DCiAOKernelImporter: generates equivalence classes for read access in
the ciao kernel space.

The disassembler disassembles an elf file with
an external objdump tool.
The architecture specific objdump must be configured
via cmake (ARCH_TOOL_PREFIX), e.g. arm-none-eabi- for
arm-none-eabi-objdump.
This is a precaution to avoid current and future naming conflicts with
common system libraries. libutil (part of libc) is the first, but probably
not the last example that already caused trouble twice.

The FailBochs client is not linked by the Bochs build system anymore, but
by our cmake scripts (make fail-client):
- All Bochs libraries are merged into libfailbochs.a (a new target
within the Bochs Autotools scripts).
- The previous libfail.a is *not* a merge of all Fail* libraries anymore,
but pulls these in via library dependencies.
Additionally I did a lot of build system cleanup, e.g. additional external
libraries may now be pulled in where they're needed.
