6 years agoMake Java bindings work with newer build envs (#1709)
Andres Noetzli [Mon, 26 Mar 2018 19:09:33 +0000 (12:09 -0700)]
Make Java bindings work with newer build envs (#1709)

Our current build scripts did not work with Automake 1.16. At configure
time, the .swig_deps target in src/bindings/Makefile.am was executed due
to the `@mk_include@ .swig_deps` (which is not the case with older
versions of Automake). This ultimately caused configure to fail because
SWIG was complaining about missing files (generated source files, such
as src/expr/expr.h). This commit fixes the issue by adding
`-ignoremissing` to the call to SWIG. With that option, SWIG is not
complaining about the missing files and the dependency generation
completes successfully.

Currently, the src/bindings/compat/java/create_impl.py script is not
compatible with Python 3, which leads to errors when building on systems
where `python` links to Python 3 (e.g. on Arch Linux). This commit makes
the script compatible with both Python 2 and 3.

Our build scripts were using old -source/-target versions when calling
`javac`. Those are not supported by newer Java versions (e.g.  Java 9).
This commit updates the version to 1.6, which is still fairly old, so
should be broadly supported.

Finally, some systems (e.g. Arch Linux' AUR package for SWIG 2) refer to
SWIG 2 as `swig-2`.  This commit adds support for detecting this at
configure time.

 Move regression tests to single Makefile.am (#1658)

Until now, regression tests were split across tens of different
Makefile.am, which required a lot of code duplication and does not
really seem to be in the spirit of automake. If we want to change the
LOG_COMPILER/LOG_DRIVER for example, we have to change every single
Makefile.am, which is cumbersome (I was able to get something
semi-working by exporting those variables but it didn't seem very
clean). Additionally, it made the output of the regression tests fairly
verbose and split the output across multiple log files. Finally
it also limited parallelism when running the regression tests (this fix lowers
the time it takes to run regression level 1 from 3m to 1m45s on my
machine with 16 threads).

This commit moves all the regression tests into
test/regress/Makefile.tests and changes test/regress/Makefile.am to deal
with this new structure. Finally, it changes how the test summary in
test/Makefile.am is produced: instead of relying on the log files for
the subdirectories, it greps for the test results in the log files of
the individual tests. Not the most elegant solution but we should
probably anyway delegate that task to a Python script at some point.

Unrecursified and merged bv::utils::is(Core|Equality)Term. (#1605)

This unrecursifies and merges bv::utils::isCoreTerm and bv::utils::isEqualityTerm to avoid
code duplication.

In the best case, the recursive implementation visits less nodes. This can be achieved with
the non-recursive implementation, however, at the cost of increased code complexity.
In practice, on QF_BV the new implementation slightly improves performance.

Tested against the recursive implementation with a temporary assertion on regression
tests (bv::utils::isCoreTerm was tested with --bv-eq-slicer=auto).
Further tested on QF_BV with a TO of 300s (slight performance improvement).

destructor did not clean up the allocations).
