Subject: * Backed out week-old attempt at enabling quadword memory access on
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b0b39eb2de25862b18d574bca791e39c3643c231;p=binutils-gdb.git

* 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.

Thu Apr  9 16:42:54 1998  Frank Ch. Eigler  <fche@cygnus.com>

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