* Backed out week-old attempt at enabling quadword memory access on
MIPS sim; added PKE sim code fixes. No COP2 testing progress today.
[ChangeLog]
Thu Apr 9 16:38:23 1998 Frank Ch. Eigler <fche@cygnus.com>
* r5900.igen (LQC,SQC): Adapted code to DOUBLEWORD accesses
instead of QUADWORD.
* sim-main.h: Removed attempt at allowing 128-bit access.

* sky-pke.c (read_pke_pc): Corrected PKE PC calculation
to word granularity.
