MIPS R6 removed the BEQL instruction so do not try to emulate it
if the R2-to-R6 emulator is not present.

How does this affect code for the old ISAs, MIPS-II to MIPS-IV?  I.e., the SGIs
and the R10K CPUs that have to worry about the R10000_LLSC_WAR workaround and
use branch-likely insns?

--J

it does not affect them (or should not affect them). In case of *any*
non-R6 core, the NO_R6EMU macro is false, so all the conditionals here
are evaluated to false and the branch emulation will do the right thing.
