Export the values of the following standard compiler and compiler flag
variables in the main makefile, avoiding the need to pass through each
one to child make processes manually:
CC
CXX
LD
JAVAC
JAVACC
Since JAVAC is manually exported as "$(JAVAC) $(JFLAGS)" by the main
makefile, additionally separate JAVAC and JFLAGS into separate variables
from the perspective of child make processes.
Rename the following makefile variables to their standard implicit
equivalents in GNU Make for the sake of clarity:
C -> CC
CPP -> CXX
CPPFLAGS -> CXXFLAGS
Rename the following makefile variables for the sake of clarity in child
makefiles:
SRC_DIR -> PRISM_SRC_DIR
CLASSES_DIR -> PRISM_CLASSES_DIR
OBJ_DIR -> PRISM_OBJ_DIR
LIB_DIR -> PRISM_LIB_DIR
INCLUDE_DIR -> PRISM_INCLUDE_DIR
IMAGES_DIR -> PRISM_IMAGES_DIR
DTDS_DIR -> PRISM_DTDS_DIR
The helper script src/scripts/printversion.sh also makes use of the
value of SRC_DIR exported from the main makefile, so use PRISM_SRC_DIR
in that script too.
We want to allow MTBDD engine model checking without having an ODD
to encode the BDD state to index information. This allows to deal
with models where the state space is too big for the ODD index type (2^63).
Here, we harden all the places where the ODD information is accessed
to gracefully handle the abscence of the ODD:
* When trying to convert from MTBDD to explicit vector, a
missing ODD is fatal
* When printing state values or a state list, index information is
not available and thus omitted
* For the hybrid and sparse engine, the odd index checks (whether
the number of states fit into an int32_t) are now done using
helper functions that handle both null ODD and out-of-range values.
As noted in #68, the javah tool has been removed in JDK10. Here, we switch to the new way of generating the JNI .h files, using the -h option of the regular javac compiler.
We have to adapt all Makefiles (not only those in directories that contain classes with native methods), as javac compiles all required classes (and generates their JNI headers) beyond the directory with the Makefile.
The .h files generated by javac -h had a different naming scheme, now there is a prefix for the package name. To avoid having to touch all the #includes, we generate the new .h files in prism/include/jni and provide legacy headers in the old location and with the old name, forwarding the the corresponding new header. In the future, at an appropriate moment, those legacy headers can be removed and replace with direct includes.
Currently, there is a post-processing step on Windows: After the .h file is generated, dos2unix is called to replace the Windows CRLF line endings. Otherwise, the generated headers show up as changed files in version control. As now there are no special targets for the generation of the .h files anymore, we move to a global post-processing step and call dos2unix on prism/include/jni/*.h at the end of building.
It looks like the value of col_offset is never actually used
during the recursion steps. For the moment, we just initialise with 0
(can not be worse than starting with uninitialised value) and mark
as candidate for refactoring after thorough inspections of
the various code paths.
(via linting)
Currently, building PRISM with parallel building does not work,
as there are dependencies between targets that are not fully
encoded in the Makefiles. Building with -j n flag would lead to error.
Now, we add the .NOTPARALLEL target to most of the Makefiles,
which tell GNU make to ignore the -j flag. Note that this
only inhibits parallel builds for the current Makefile, we
thus have to specify it for all sub-Makefiles as well
(see https://www.gnu.org/software/make/manual/html_node/Parallel.html)
For the external libraries, CUDD and LPSolve don't seem to mind building
in parallel, so we don't inhibit there and can get some minor compile time
speed-up by using multiple cores if the -j option is specified.

Consistently include cstdio instead of stdio.h, etc. For MinGW,
the default underlying stdio implementation (Microsoft DLL based vs
POSIX MinGW implementation) differs between C++ and C code, so
format string warnings pop up if we include the C header...

On Win32, jints are actually long ints, so printf would need %ld instead of %d.
As jints are 32bit, we simply cast to an int to silence format string compiler
warning.

Generates HTML file with the individual steps of the iterative procedures.
Relies on external JavaScript and CSS.
Is already prepared for exporting interval iteration steps (possibility
to export multiple vectors with type flag per iteration step)

Currently, the hybrid engine internally uses int (signed 32bit) index variables
So, if the number of states is larger than Integer.MAX_VALUE, there is a problem
and the code will most probably crash or do nonsensical things.
We check this before calling into the native hybrid engine code and
throw a PrismNotSupportedException.

Technically, using 'plain' delete for deleting objects allocated with
new[] is undefined behaviour. In practice, this didn't appear to be a
problem.

- better catching of memory-out errors
- improved clarity of memory usage output
- removed various memory leaks
- now consistently use new/delete, no malloc/free
