jtreg has no direct, complete solution for mixed code like this, and is
unlikely to support
it any time soon.
You can use Makefiles from a shell script, but that is unlikely to be
successful in a
broad multi-platform world, like OpenJDK. Not only is it problematic to
compiler to use and where to find it, but at least in our internal test
the test machines may not even have the native code compilers installed.
(i.e. it is common practice to build and test on different host systems.)
The compromise solution we adopted in conjunction with the Hotspot SQE team
is to use the OpenJDK build process to compile the C/C++ code needed for
The build has the info needed on how to do platform-specific compilation
code. The build can then generate a bundle that can be passed to jtreg
I cannot speak to the existence of Makefiles appearing in the regression
Sometimes they are used manually to create native files that are checked
in to the
repo (uugh) and sometimes the tests are restricted to run on a limited
set of platforms
(e.g. Windows only, or Unix only.)
