The current sim lacks any sort of tests. Start a basic framework and
add a simple one to test the add insn.

If we want to run a simple ELF, the reset vector isn't set up, so starting
at address 0 doesn't make sense. Use the ELF's entry point instead.

This fix is simple:
msp430-sim.c: In function 'maybe_perform_syscall':
msp430-sim.c:898:10: warning: format '%d' expects argument of type 'int',
but argument 5 has type 'long int' [-Wformat]
This one we change to use casts like everyone else does in the code base:
msp430-sim.c: In function 'msp430_step_once':
msp430-sim.c:985:7: warning: passing argument 3 of 'init_disassemble_info'
from incompatible pointer type [enabled by default]
include/dis-asm.h:368:13: note: expected 'fprintf_ftype' but argument is
of type 'int (*)(struct FILE * __restrict__, const char * __restrict__)'

It is rare for people to want to modify the cmd arg. In general, they
really shouldn't be, but a few still do. For those who misbehave, dupe
the string locally so they can bang on it.
|
|
There's no need for the prog_name handed down to the core to be mutable,
so add const markings to it and all the related funcs.
|
|
Most of these prototypes have been killed off, but we have a few left
in the sim tree. Clean them up so we can enable the -W flag for it.

sim/rx/gdb-if.c had a function named `rx_signal_to_host'. This
function mapped signal numbers used by the BSP to host signal
numbers which, at one time a while back, were used by GDB
as target signal numbers. This change updates the signal
numbers returned to be those names prefixed with "GDB_SIGNAL_"
as defined in include/gdb/signals.h.
It also changes the name of the function somewhat to better
match what the function currently does. I noticed that this
function is not static - and there's no reason for it not
to be - so I made it static too.
* gdb-if.c (rx_signal_to_host): Rename to
`rx_signal_to_gdb_signal'. Make static. Update all callers
to use new name. Use signal names from include/gdb/signals.h.

Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:
sigsave = signal (SIGINT, interrupt);
However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.

When cross-compiling GDB for PPC, there's a prerequisite "-lz" for psim
that results in a build failure. With such prerequisite, GNU Make will
try to search the library from build machine's /usr/lib which is wrong.
On 64-bit Linux build machines the compilation will fail because of this.

The SEARCH insn is an oddball when it comes to parallel usage. It places a
big limit on what other insns it can run in parallel with, but we don't
currently track the amount of state needed to verify this (since no other insn
really requires this). Add a note for now in case we get around to it.
|
|
For many of the 32bit dsp shift related insns, we were just ignoring the HLs
field. The hardware does not though and will reject the insn if it's set
incorrectly. Update the sim to match.
|
|
|
|
Since the sim has a few fake debug insns that the hardware does not, we
need to check for those before attempting to run them. Otherwise we'll
randomly trigger the sim debug asserts/aborts/halts insns. On the
hardware, these are proper invalid insns, and the table catches that.
|
|
The main body of the "all insn" test is executed once per tested insn, and
we test millions of insns here. Any shrinkage we can do in this loop will
speed things up nicely (since it's multiplied per tested insn).
To that end, simplify the end-of-table test into one less insn, and omit
the SSYNC when we build for the sim. When we build to run on the hardware,
this insn matters, but the sim doesn't have write store buffers in the chip
that might get in the way (memory writes are atomic).

We wrote a test case that tries every single 32bit opcode on the hardware
and compared it to the sim. There were a bunch of places in the sim where
we weren't strict enough (requiring certain parts of the opcode be set) so
we were treating a lot of invalid opcodes as valid ones. This sprinkles
out a lot additional checks in the dsp32alu class.

Since these insns run in usermode, there should be no need to setup
RET[ENI] to safe values. They won't be dereferenced, and any insn
that returns via them are valid only in supervisor mode. Since this
is in the main exception code path, saving any insn at all is good
as it gets multiplied quickly (as in O(n^2) times).

Since many people don't have a Blackfin toolchain available, only try to
regenerate the header file when in maintainer mode. This file rarely changes,
and when it does, we commit the generated output, so there's almost never a
need to run directly on an end system.
|
|
I noticed the sim code is using an old implementation of the maintainer logic.
I cut it over to the new macro (like gdb has been doing). In practice, it
makes no difference currently as nothing in the sim tree uses it, but I have a
follow up commit for the Blackfin tree that needs it.
