# Integrate with libjvm. Here we generate three object files which are
# linked with libjvm.so. This step is complicated from a dependency
# perspective, since it needs the rest of the compiled object files from the
# libjvm compilation, but the output is object files that are to be included
# when linking libjvm.so. So this generation must happen as a part of the
# libjvm compilation.
# First we need to generate the dtraceGenOffsets tool. When run, this will
# produce more header files and a C++ file.
# Note that generateJvmOffsets.cpp must be compiled as if it were a file
# in the libjvm.so, using JVM_CFLAGS as setup in CompileJvm.gmk. Otherwise
# this would preferrably have been done as a part of GensrcDtrace.gmk.
