All the runtimes were only initializing a single CPU. When SMP is
enabled, things quickly crash as none of the other CPU structs are
setup. Change the default from 0 to the compile time value.
|
|
The igen tool sets up the SD define for code fragments to use, but
mn10300 was expecting "sd". Change all the igen related code to use
SD so it actually compiles.
|
|
Now that igen itself has this logic, drop these custom build rules
to greatly simplify.
|
|
Rename mn10300_sim.h to mn10300-sim.h to match other ports, and move most
of the arch-specific content out of sim-main.h to it. This isn't a big
win though as we still have to include the header in sim-main.h due to the
igen interface: it hardcodes including sim-main.h in its files. So until
we can fix that, we have to keep bleeding these settings into the common
codes.
Also take the opportunity to purge a lot of unused headers from these.
The local modules should already include the right headers, so there's
no need to force everyone to pull them in. A lot of this is a hold over
from the pre-igen days of this port.

This reverts commit 681a422b855e4b20086554b170dae051361f00c7.
I missed that this was included via common/sim-inline.c. I thought
I had grepped the top of the tree, but I must have only done mn10300.
Add a comment to make it clear where/how this file is used.

Nothing compiles or references this, so punt it.
|

We need these in the top-level to generate libsim.a, but also in the
subdirs to generate hw-config.h. Move it to the local.mk, and pass
it down when running recursive make. This avoids duplication, and
makes it available to both. We can simplify this once we move the
various steps up to the top-level too.
|
|
All ports should be migrated now. Drop the SIM_HAVE_COMMON_SIM_CPU
knob and require it be used everywhere now.
|
|
Currently all ports have to declare sim_cpu themselves in their
sim-main.h and then embed the common sim_cpu_base in it. This
dynamic makes it impossible to share common object code among
multiple ports because the core data structure is always different.
Let's invert this relationship: common code declares sim_cpu, and
the port uses the new arch_data field for its per-cpu state.
This is the first in a series of changes: it adds a define to select
between the old & new layouts, then converts all the ports that don't
need custom state over to the new layout. This includes mn10300 that,
while it defines custom fields in its cpu struct, never uses them.

We've been using this only to set the default word size to 32. We
can easily move this into the makefile via a -D compiler flag and
clean up the build logic quite a bit.
|

Automake will run each subdir individually before moving on to the next
one. This means that the linking phase, a single threaded process, will
not run in parallel with anything else. When we have to link ~32 ports,
that's 32 link steps that don't take advantage of parallel systems. On
my really old 4-core system, this cuts a multi-target build from ~60 sec
to ~30 sec. We eventually want to move all compile+link steps to this
common dir anyways, so might as well move linking now for a nice speedup.
We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care
of the install ourselves rather than letting automake process it.
|
|
These manual settings were necessary when we weren't doing automatic
header dependency tracking. That was changed a while ago, and we use
automake now to do it all for us. As a result, many of these vars
aren't even referenced anymore.
Further, some of the source file generation (e.g. .c files, or igen,
or cgen outputs) were moved to the common automake build, and it takes
care of dependency tracking for us with the object files.
|
|
When reading/writing arbitrary data to the system's memory, the unsigned
char pointer type doesn't make that much sense. Switch it to void so we
align a bit with standard C library read/write functions, and to avoid
having to sprinkle casts everywhere.
|
|
These functions only read from memory, so mark the pointer as const.
|
|
This was left in subdirs because of the dynamic cgen usage. However,
we can move this breakpoint call to runtime and let gdb detect whether
the symbol exists.
|
|
This old port setup its own uintXX types, but since we require C11
now, we can assume the standard uintXX_t types exist and use them.
|
|
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
|
|
The ## marker tells automake to not include the comment in its
generated output, so use that in most places where the comment
only makes sense in the inputs.
|
|
Avoid use of TARGET_<syscall> defines and rely on the callback layers
to resolve these dynamically so we can support multiple syscall layers
instead of assuming the newlib/libgloss numbers all the time.
|
|
We use the program argv to both find the program to run (argv[0]) and
to hold the arguments to the program. Most of the time this is fine,
but if we want to let programs specify argv[0] independently (which is
possible in standard *NIX programs), this double duty doesn't work.
So let's split the path to the program to run out into a separate
field by itself. This simplifies the various sim_open funcs too.
By itself, this code is more of a logical cleanup than something that
is super useful. But it will open up customization of argv[0] in a
follow up commit. Split the changes to make it easier to review.
|
|
These rules don't depend on the target compiler settings, so hoist
the build logic up to the common builds for better parallelization.
We leave the mips rules in place as they depend on complicated
arch-specific configure logic that needs to be untangled first.
|
|
The void *data field is used to past arbitrary data between event
handlers, and these are using it to pass an enum. Fix up the casts
to avoid using (long) to cast to/from pointers since there is no
guarantee that's the right size.
|
|
Add a new stamp helper for quiet builds, and don't dump the command
line options when it runs. That isn't standard tool behavior, and
doesn't really seem necessary in any way.
|
|
We pretty much never care about these stamp touches, so silence them.
Also switch to using $@ when it makes sense.
|
|
Use the srcroot path and make them all silent.
|
|
Now that ChangeLog entries are no longer used for sim patches,
this commit renames all relevant sim ChangeLog to ChangeLog-2021,
similar to what we would do in the context of the "Start of New
Year" procedure.
The purpose of this change is to avoid people merging ChangeLog
entries by mistake when applying existing commits that they are
currently working on.
Also throw in a .gitignore entry to keep people from adding new
ChangeLog files anywhere in the sim tree.

Move these options up to the common dir so we only test & export
them once across all ports.
The setting only affects igen based ports, and they were turning
this on by default, so keep the default in place.
|
|
The cgen scache module is enabled by every cgen port, and with the
same default value of 16k (which matches the common default value).
Let's pull this option out of the individual ports (via CPPFLAGS)
and into the common code (via config.h).
The object itself is compiled only for cgen ports atm, so that part
doesn't change. The scache code is initialized dynamically via the
modules.c logic. That's why the profile code needs an additional
CGEN_ARCH check.
This will allow us to collapse arch configure files more. Merging
the source files will require more future work, but integrating the
cgen & non-cgen worlds itself will take a lot.
|
|
This kills off another compile-time option by moving the setting to
the individual arch runtimes. This will allow dynamic selection by
the arch when doing a single build with multiple arches.
The sim_model_init rework is a little funky. In the past it was
disabled entirely if no default model was set. We maintain the
spirit of the logic by gating the fallback logic on whether the
port has defined any models.
|
|
These ports only use the pieces that have been unified, so we can
merge them into the common configure script and get rid of their
unique one entirely.
We still compile & link separate run programs, and have dedicated
subdir Makefiles, but the configure script portion is merged.

The sim-hardware configure option allows builders to select a set of
device models to enable. But this seems like unnecessary overkill:
the existence of individual device models doesn't affect performance
at all as they are only enabled at runtime if the config uses them,
and individually these are all <5KB a piece. Stripping off a total
of ~50KB from a ~1MB binary doesn't seem useful, and it's extremely
unlikely anyone will ever bother.
So let's simplify the configure/make logic by turning sim-hardware
into a boolean option like many of the other sim options. Any ports
that have unique device models will declare them in their Makefile
instead of at configure time. This will allow us to (eventually)
unify the setting into the common dir.
|
|
Now that we've moved all content out to the common file, this is
empty and can be deleted it entirely.
|
|
Move these options up to the common dir so we only test & export
them once across all ports. This takes a page from the cgen maint
logic to make $(MAINT) work for non-automake Makefiles which will
allow us to merge it together.
|
|
This will allow us to build the common code with the same inline
settings as the arch subdirs, and only do the test once.
|
|
Move these options up to the common dir so we only test & export
them once across all ports.
|
|
The common dir is already probing this info since it's using automake,
so pass it down to the subdirs so they don't have to probe it at all.

|
|
Move these options up to the common dir so we only test & export
them once across all ports. It also enables -Werror usage on the
common files we've been pulling out of arch subdirs.
|
|
For the ports that still don't build with -Werror, rather than disable
the flag at configure time, do it at make time. This will allow us to
unify these tests in the common sim configure script.
|
|
The sim-basics.h is too big and includes too many things. This leads
to some arch's sim-main.h having circular loop issues with defs, and
makes it hard to separate out common objects from arch-specific defs.
By splitting up sim-basics.h and killing off sim-main.h, it'll make
it easier to separate out the two.
|

The m4 macro has 2 args: the "wire" settings (which represents the
hardwired port behavior), and the default settings (which are used
if nothing else is specified). If none are specified, the arch is
expected to support both, and the value will be probed based on the
user runtime options or the input program.
Only two arches today set the default value (bpf & mips). We can
probably let this go as it only shows up in one scenario: the sim
is invoked, but with no inputs, and no user endian selection. This
means bpf will not behave like the other arches: an error is shown
and forces the user to make a choice. If an input program is used
though, we'll still switch the default to that. This allows us to
remove the WITH_DEFAULT_TARGET_BYTE_ORDER setting.
For the ports that set a "wire" endian, move it to the runtime init
of the respective sim_open calls. This allows us to change the
WITH_TARGET_BYTE_ORDER to purely a user-selected configure setting
if they want to force a specific endianness.
With all the endian logic moved to runtime selection, we can move
the configure call up to the common dir so we only process it once
across all ports.
The ppc arch was picking the wire endian based on the target used,
but since we weren't doing that for other biendian arches, we can
let this go too. We'll rely on the input selecting the endian, or
make the user decide.

Use INLINE2 instead of INLINE to fix builds when -O0 are used -- the
latter define is omitted at -O0 levels while the former is always
set to inline. These helper funcs are used by defines in here but
the defines aren't always called.
|
|
The current autoconf 2.69 defines this to nothing because the logic
in AC_PROG_CC takes care of it all the time now. Delete the call.
|
|
All of the settings in here are handled by the common top-level
config.h, so drop the individual arch-config.h files entirely.
This will also help guarantee that we don't add any new arch
specific defines that would affect common code which will help
with the effort of unifying them.
|
|
This is the only define left in m4/ that is not in the common config.h,
so move it to sim_hw_cflags so we can drop the arch-specific config.h.
|
|
Now that all warnings are fixed in this port, enable -Werror by default.
|
|
This allows the caller to catch engine aborts if they want, and fixes
the warning about missing stdlib.h include by not using abort().
