See ??? comments here and in cgen, and in libgloss/i960.Simulator:Update sim/i960 directory from sim/m32r directory.  sim/i960 dir was createdby copying the sim/m32r in September 1998, and is missing all sim/m32r updatessince then.Review, clean up, finish, etc simulator files that are not cgen generated.This includes devices.c, i960-sim.h, mloop.in, sim-if.c, sim-main.h,tconfig.in, and traps.c.Some functions do not show up in trace output.  This occasionally happensfor main.Gdb core dumps if compile without -mka.  Apparently a problem with recognizing"core" machine type.Get profiling working.Add pipelining, execution unit, timing, etc info.Add support for other models, besides KA.Add support for newer architectures, e.g. v1.1 instructions.Compiler:Running gcc gives nm warning from collect about missing a.out file.The output file is b.out, not a.out.  Collect is probably looking forthe wrong file name.Use of -mca gives lots of linker warnings for ka/ca architecture conflicts,but the two architectures are compatible.Need 96 bit long double support in fp-bit.c, otherwise any testcase usinglong double arithmetic hits an abort and runtime.Compiler takes far too much time to compile PlumHall testcases at highoptimization levels.r2 seems to be an available call-clobbered registers, since it isn't useduntil a call occurs, and is dead when the call returns.BSP:Libgloss does not check for syscall error returns, which means errno nevergets set.Libgloss does not use the syscall.h file.Binutils:Objdump -d fails on 64-bit host, specifically irix6.Gdb:Gdb sometimes prints messages about trace/breakpoint trap when hitting abreakpoint.Frame, up, down and related commands don't work.Gdb fails when next'ing over a leaf function compiled with -mleaf-procedure.Gdb fails when step'ing over a return from such a leaf function.
