+See ??? comments here and in cgen, and in libgloss/i960.
+
+Simulator:
+
+Update sim/i960 directory from sim/m32r directory.  sim/i960 dir was created
+by copying the sim/m32r in September 1998, and is missing all sim/m32r updates
+since 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 happens
+for 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 for
+the 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 using
+long double arithmetic hits an abort and runtime.
+
+Compiler takes far too much time to compile PlumHall testcases at high
+optimization levels.
+
+r2 seems to be an available call-clobbered registers, since it isn't used
+until a call occurs, and is dead when the call returns.
+
+BSP:
+
+Libgloss does not check for syscall error returns, which means errno never
+gets 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 a
+breakpoint.
+
+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.
