            Bug ID: 239805
           Summary: adding dtrace support for  aarch64
           Product: Base System
           Version: 12.0-RELEASE
          Hardware: arm64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: arm
          Assignee: freebsd-arm at FreeBSD.org
          Reporter: maciphone2 at googlemail.com

as referenced for other applications (e.g. bug#224271 )
this also affects :

dtrace: failed to link script
/root/openjdk-jdk11u/build/bsd-aarch64-normal-server-fastdebug/hotspot/variant-server/support/dtrace/dtrace.od:
an error was encountered while processing / root / openjdk jdk11u / build /

dt_modtext: /usr/src/cddl/contrib/opensolaris/lib/libdtrace/common/dt_link.c
(811): aarch64 not implemented


from here :
https://github.com/freebsd/freebsd/blob/master/cddl/contrib/opensolaris/lib/libdtrace/common/dt_link.c

at Oracle looks better for aarch64:
https://github.com/oracle/dtrace-utils/blob/master/libdtrace/dt_link.c
(dt_link.c implements aarch64)


I just wanted to invite a few more experts to try a patch based on the Oracle
sources , thanks
