This includes using nm again, instead of llvm-nm.

Use the configuration values in the code (forced include) and within the
generator itself. This needed some adaptions to the code.

We actually need a cross compiler setup, even for the i386 variant.
This change invokes the i386-elf- toolchain.
(It only worked in Linux, as it uses the same ELF format for executables)

The corresponding tools (nm, objdump) are propagated to the various
scripts and builds.

Fixes for Linux variant.
Fixes for posix variant.
Use /proj/i4danceos/tools/llvm-3.4 as Hint

SSE and state assertions can be now configured within ccmake
or new_build_env script.
Most important variant variables are prefixed with dOSEK_
(in order to be grouped nicely in ccmake)

For tracing all test-suite benchmarks a few modifications on the
test-cases had to be done in the FAIL case:

- remove long busy wait states
- There has to be at least one instruction between two system
  call. Otherwise trace-analyze cannot easily distinguish both system
  calls.

Also the trace-analyze.py had to be fixed at a few places.

- correct CMake invocation
- get size of irq_resume from binary

fail/fail-runner.py: stop clients on campaign finish
fail/fail.R: skip os_stack graph if empty to prevent error
eval/fail.sh: save statistics, binary of experiments
fail/CMakeLists: always create statistics after tracing

The work needed to maintain the manually "generated" system files is no longer
worth the effort for the constructor test alone.

Refactored tests to single "tests" target
This can also be used to *run* tests in parallel:
make -j8 tests && ctest -j8

For later evaluation purposes, we have to match syscall regions with
runtimes. We accomplish this by using the fail golden run of a
benchmark. All systemcall regions are identified and then mapped to
syscall ABBs.

First try at evaluation scripts. These build and run FAIL* tests for
all variants (encoded/unencoded, mpu/nompu) for all given apps.
After this, result graphs are created by R and saved as a single PDF.
Additionally, the (joined) result data returned from the database is
saved as a R (data frame) object.

Example usage: ./fail.sh bench-task1a bench-complex1d

The R script uses $HOME/my.cnf to connect to the database.
To map addresses to symbol names, objdump information for the .data
section is saved to .syms files.

This header defines functions and variables for FAIL* tracing
experiments, which compare system state at all points where test_trace
is called.
Function names are taken from test.h to allow easy FAIL* testing of
apps using test.h.
Using noinline test and test_finish functions removes the need to
define additional marker functions for FAIL*.

- add checkpoint.trace to FAIL* dependencies
- FAIL* runner: terminate on server exit, better output
- multiple FAIL apps no longer overwrite CMake variables

FAIL_OPTS was only set for the first experiment...

Change-Id: I40a39cbba7cfc56c1e9faf40a95e6a24db8cbc2f

FAIL_OPTS was set before FAIL_VARIANT is set

- check for clean git workspace before tracing
- store git SHA1 hash in FAIL* variant name to distinguish FAIL*
  experiments
- CMake needs to be re-configured after each commit to reflect the new
  hash. If the python check script detects a new hash before tracing,
  the build will be aborted and a message to re-run the build is displayed.
  As the git revision file is updated by the check script, and the CMakeFile
  uses this to configure_file() a dummy output, the next build will trigger a
  CMake re-configure as intended.

FAIL* benchmarks run without MPU protection are now suffixed
with "-nompu"

Change-Id: I0ab5c6c476ce4c095d836b5499d97d9b1186c8d9

FAIL* benchmark names are suffixed with "-unencoded" if the
unencoded system is built

Change-Id: I70c29b43e7ee2096a5349089ba6df8865884613e

New options of ObjdumpImporter to import sources and debug information
(line numbers) into the database are activated.

Since Bochs output (files) have been reduced a missing output file caused
CMake to rerun the entrire FAIL* toolchain on each call.

All manually hand-crafted testcases already work just. Counter/Alarms
are implemented with itimer. The Task switch is at the moment a manual
x86 stackswitch. Perhaps we want to replace this again with ucontexts.

FAIL* targets will be generated if FAIL option is given in
COREDOS_BINARY macro.

- set compile definitons (FAIL=1) correctly for .prelink.elf in
  coredos_executable macro
- use Null_Stream for kout and debug in FAIL* binaries
- disable debug, serial output in Bochs for FAIL* testing
- add proper CMake dependency on linker scripts

The tasklist/scheduler/alarms are fully or partially depended on the
generation process. Therefore we have to extract the curring testing
system to a seperate file. This is also handy to have a template of
code that can be used in the generation process.

Change-Id: Ib774bd5571b6145658a365bcc332abc93e4253be

- moved i386-adapter linker script to arch/i386
- moved i386-adapted coredos_executable macro from arch/generic to arch/i386
- static GDT initialization (kernel, userspace, TSS)
- static IDT initialization, generic handler(s)
- static paging: pagetables are generated from a "prelink" executable with empty tables
  and then linked together into the final executable
- Linker script layout changes for memory protection, page alignment, RAM/ROM separation
- i386 exception codes in arch/i386/exception.h
- cleaned up arch/i386/startup.s
- prevent debugtest, failtest targets from always being built

Change-Id: Idcc0c9b64b14e0ac03c755ba972620ec5979ea4e

- Added fail directory for FAIL* testing
- Lots of CMake targets to automate all aspects of FAIL* testing:
  Tracing, Objdump-Import, Region-Mapping, Importing, Pruning, Server, Client
- fail-run.py to run one or #cores FAIL* clients, optionally FAIL* server as well
- mapper.py to extract allowed text/data/stack regions from elf for importers
- distributes clients to other hosts when PARALLEL_SSHFILE is set
- manlobbi.slf SSH-login file for manlobbi for parallel

Usage:
- Use coredos_fail_test(TESTNAME) instead of coredos_test(TESTNAME) in CMakeFiles
- Run FAIL* server+client in one shot with make fail-TESTNAME-TYPE
  TYPE names importer type: mem, regs, ip or jump

Some relevant CMake-Variables:
FAIL_TOOLS_DIR: directory where FAIL* tester+tracing binaries are, defaults to
  /proj/i4danceos/coredos/cored-tester
FAIL_DBNAME/FAIL_HOSTNAME/FAIL_USERNAME: override ~/my.cnf if needed
FAIL_NICE: Set client nice level
FAIL_VARIANT: Variant name, benchmark name derived from target and importer type
PARALLEL_SSHFILE: SSH login file to distribute FAIL* clients to
