This doesn't clean up all the warnings, just most of them.
The ones that are left will require some care to unravel.
|
|
Now that all targets have been converted to nrun, we can finally punt
this old inconsistent interface.
A few stray references to the old run were sprinkled about; clean them
up in the process.
We leave behind the run(1) man page mostly so that we get it updated for
the new nrun interface.
|
|
With zlib being mandatory, and the updated m4 configs, we need to regen
and use the new settings w/bfd to avoid linkage errors.
|
|
While cleaning up stale make rules, one too many were deleted. The
build system autogenerates static rules, but not generated files.
|
|
With newer versions of gcc (5.x), the extern inline we're using with the
cgen-{mem,ops} modules no longer work. Since this code really wants the
gnu inline semantics, use that attribute explicitly.

A lot of cpu state is stored in global variables, as is memory handling.
The sim_size support needs unwinding at some point. But at least this
is an improvement on the status quo.
|
|
|
|
Also delete a few unused funcs.
|
|
In preparation for converting to nrun, call the common functions that
are needed. This doesn't produce any new warnings, and the generated
code should be the same.
|
|
These values are the same all the time, so just list them directly in
the Makefile.

This hook is used only when linked into gdb, and d10v doesn't have a gdb
port anymore. Punt it.

Looks like historical restructuring in this dir lost the d10v-elf subdir
and no one noticed in the meantime. Re-add it to the testsuite.
There are some failures, but better some tests get run than none at all.

This code is getting in the way of porting to nrun, so just drop it.
If anyone actually cares about this cpu, they can revive it.

The current cr16 testsuite sets up _START, but the linker looks for the
_start symbol. Add the latter as an alias to the former.
|
|
This port already was storing its cpu state in the sim_cpu structure, so
converting it over was pretty easy. It is allocating memory itself still,
but we'll fix that up in the future at some point.
|
|
The mcore port had a few structs/defines that were never used.
Similarly, the microblaze port, because it was copied from mcore, has
that same dead code, and more. The watchpoint logic was never actually
used. Punt it all.
|
|
Since the sim doesn't have any debug support in it, we can only exit
cleanly. But this is still better than nothing.
Change the default microblaze sim to not dump the debug load output
when running. No other does this, and it breaks the testsuite.
|
|
If a test doesn't write anything at all to stdout, the current test
framework can't support that. Even if you put a blank output line:
# output:
the setup happily clobbers that with a default pass/fail string.
Tweak the parsing logic so we only set the output to pass/fail when
the test has no output marker.

sim-arange module no longer works. Since this code really wants the gnu
inline semantics, use that attribute explicitly.

Since the testsuite subdir has to handle dynamic arch values already,
there's no real value in requiring arches to opt in to it. Most have
a testsuite now anyways, and we're requiring it in the future.

The sbrk syscall assumes the sbrk region starts after the bss and the
current implementation requires a bss section to exist. Since there
is no requirement for programs to have a bss in general, we want to
drop this check. However, there is still the sbrk syscall that wants
to know about the region.
Since libgloss doesn't actually use the sbrk syscall (it implements
sbrk in its own way), and the sim really shouldn't enforce a specific
memory layout on programs, lets simply delete sbrk support. Now it
always returns an error.
|
|
Make sure we use the symbol the linker expects by default, and we export
it so it can be found.

Mostly converting old style prototypes. Also include a few missing
headers, and add static/casts where appropriate.
|
|
A missing */ caused a case statement to be incorrect masked out which
also hide an error where the wrong value was being checked. Fix both.
|
|
The build line was missing the normal BUILD_xxx flags. Once we added
that, we get warnings that weren't shown before. As we fix those, we
notice that the -d option segfaults because it tries to write readonly
memory. Fix that too as part of the const/prototype clean up.

a time.
|
|
Looks like a lot more work than actually was -- the main decode loop
was de-indented by dropping the loop as a step-once function.
|
|
Just enough to know the sim isn't totally broken.
|
|
|
|
Use separate memory_iread() function for instruction fetching.
Speeds up execution and allows addition of an MMU at a later stage.

FT32 is a new high performance 32-bit RISC core developed by FTDI for
embedded applications.
|
|
The previous profile change broke these sims that use sim-profile but
not sim-cpu (due to missing model support). Add simple funcs until we
can convert these over properly.
|
|
The profile code was using STATE_WATCHPOINTS to get access to the PC, but
we already have a standard method for getting the pc, so switch to that.
This assumes that sizeof_pc is the same size as sim_cia, but we already
assume this in places by way of sim_pc_{get,set}, and this is how it's
documented in the sim-base.h API.
|
|
|
|
This port already used a lot of common/ files, so cutting it over to
nrun.o and using a few more common objects is pretty straight forward.
