1. Dtrace currently doesn't work on powerpc64. I'm not sure whether it work=
s on
CURRENT, but enabling it on 12 causes assertion errors from base. Consider
following patch:

2.
https://svnweb.freebsd.org/ports/head/lang/ghc/files/patch-ppc64?r1=3D49456=
2&r2=3D506142
is another breakage on powerpc64 elfv1. Reverting to previous version of
patch-ppc64 works it around:
/wrkdirs/usr/ports/lang/ghc/work/ghc-8.6.5/rts/Schedule.c:451:0: error:

Could the current patch-ppc64 be applied only for elfv2 systems and for elf=
v1
the old patch be kept?
