# 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.

|

# in the libjvm.so, using JVM_CFLAGS as setup in CompileJvm.gmk. Otherwise
