+
+       * mips.igen (ADD, ADDI, DADDI, DSUB, SUB): Add comment
+       indicating that ALU32_END or ALU64_END are there to check
+       for overflow.
+       (DADD): Likewise, but also remove previous comment about
+       overflow checking.

+       * mips.igen (DDIV, DIV, DIVU, DMULT, DMULTU, DSLL, DSLL32,
+       DSLLV, DSRA, DSRA32, DSRAV, DSRL, DSRL32, DSRLV, DSUB, DSUBU,

+       ERET, RFE, TLBP, TLBR, TLBWI, TLBWR): Tweak instruction opcode
+       fields (i.e., add and move commas) so that they more closely
+       match the MIPS ISA documentation opcode partitioning.
+
+2002-02-10  Chris Demetriou  <cgd@broadcom.com>
+
+        * mips.igen (ADDI): Print immediate value.
+        (BREAK): Print code.
+        (DADDIU, DSRAV, DSRLV): Print correct instruction name.
+        (SLL): Print "nop" specially, and don't run the code
+        that does the shift for the "nop" case.
+
+2001-11-17  Fred Fish  <fnf@redhat.com>
+
+       * sim-main.h (float_operation): Move enum declaration outside
+       of _sim_cpu struct declaration.
+
+2001-04-12  Jim Blandy  <jimb@redhat.com>
+
+       * mips.igen (CFC1, CTC1): Pass the correct register numbers to
+       PENDING_FILL.  Use PENDING_SCHED directly to handle the pending
+       set of the FCSR.
+       * sim-main.h (COCIDX): Remove definition; this isn't supported by
+       PENDING_FILL, and you can get the intended effect gracefully by
+       calling PENDING_SCHED directly.
+
+2001-02-23  Ben Elliston  <bje@redhat.com>
+
+       * sim-main.h (ENGINE_ISSUE_PREFIX_HOOK): Only define if not
+       already defined elsewhere.
+
+2001-02-19  Ben Elliston  <bje@redhat.com>
+
+       * sim-main.h (sim_monitor): Return an int.
+       * interp.c (sim_monitor): Add return values.
+       (signal_exception): Handle error conditions from sim_monitor.
+
+2001-02-08  Ben Elliston  <bje@redhat.com>
+
+       * sim-main.c (load_memory): Pass cia to sim_core_read* functions.
+       (store_memory): Likewise, pass cia to sim_core_write*.
+
+2000-10-19  Frank Ch. Eigler  <fche@redhat.com>
+
+       On advice from Chris G. Demetriou <cgd@sibyte.com>:
+       * sim-main.h (GPR_CLEAR): Remove unused alternative macro.

+
+       From Maciej W. Rozycki <macro@ds2.pg.gda.pl>:
+       * Makefile.in: Don't delete *.igen when cleaning directory.

 Wed Jul 19 18:50:51 2000  Andrew Cagney  <cagney@b1.cygnus.com>
 
        * m16.igen (break): Call SignalException not sim_engine_halt.
