commit a5721ba270ddf860e0e5a45bba456214e8eac2be
Author: Alan Modra <amodra@gmail.com>
Date: Thu Sep 29 15:12:47 2016 +0930
Disallow 3-operand cmp[l][i] for ppc64
cmp[l][o] get an optional L field only when generating 32-bit code.
dcbf, tlbie and tlbiel keep their optional L field, ditto for R field
of tbegin. cmprb, tsr., wlcr[all] and mtsle all change to a
compulsory L field.
L field of dcbf and wclr is 2 bits.
