    On MacOS X, the debuginfo will be in libjvm.dylib.dSYM so
    you'll need a MacOS X specific rule. You don't need an
    update for the JVM_VARIANT_CLIENT version because MacOS X
    doesn't support the Client VM, but if it did...

So the above change handles libjvm, but what about the
other libraries exported by HotSpot? libjsig, libjvm_db,
and libjvm_dtrace come to mind...

Hi all,

this patch changes how old debug information copied from IMPORT_JDK is treated.

When running the copy_*_jdk target, HotSpot's makefiles copies the entire IMPORT_JDK folder, including additional files (such as unzipped debug information). The export_*_jdk targets will then, via the generic_export target, copy the build artifacts via implicit rules to the correct destination in hotspot/build/JDK_IMAGE_DIR.

The bug arises when IMPORT_JDK contains unzipped debug info (libjvm.debuginfo) and the make target produces zipped debug info (libjvm.diz), or vice versa. hotspot/build/JDK_IMAGE_DIR will then contain both libjvm.debuginfo and libjvm.diz, but only one of them will match libjvm.so.

Finally, the JPRT make targets jprt_build_* just zips hotspot/build/$(JDK_IMAGE_DIR). The zipped JPRT bundle will end up having different zipped and unzipped debug info, since the IMPORT_JDK in JPRT contains libjvm.debuginfo and we build libjvm.diz by default.

This patch removes the debug info that we did *not* build. If we build libjvm.diz, then libjvm.debuginfo will be removed (if it exists). Correspondingly, if we build libjvm.debuginfo, then libjvm.diz will be removed (if it exists).

Patch:
http://cr.openjdk.java.net/~ehelin/8033580/webrev.00/

Bug:
https://bugs.openjdk.java.net/browse/JDK-8033580

Testing:
- Building in JPRT
- Building Linux 32-bit locally on a Linux 64-bit machine
- Building Linux 64-bit locally on a Linux 64-bit machine

For all of the above, verify that only the correct debug info is present in the output.

Thanks,
Erik
