Description Mark Linimon freebsd_committer freebsd_triage 2018-02-19 02:16:13 UTC 
(This is a src tree equivalent to ports PR 224271, to migrate its content.  The ports tree is going to work around this for now.)

"On armv6/7 we have this error: dt_modtext:/usr/src/cddl/contrib/opensolaris/lib/libdtrace/common/dt_link.c(820): arm not implemented"

This is still heavily affecting armv7 package builds as of 20180219.  I'm taking it on myself to implement workarounds in the ports tree.

This also affects 11-STABLE and 11.1R.
Comment 2 Jan Beich freebsd_committer freebsd_triage 2018-02-19 07:45:10 UTC 
aarch64 issue is the same as armv6. It's just base r325042 changed the error message.
Comment 3 Jan Beich freebsd_committer freebsd_triage 2018-02-19 07:48:08 UTC 
Also, aarch64 uses lld since 11.1, so ld reports errors slightly different.
