-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.
