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.
|
|
Now that the traps code has been unified, the configure script has no
unique logic in it, so it can be merged into the single common one.
|
|
Now that the scache logic has been migrated into the common code,
there's nothing specific in these configure scripts, so merge them
into the common one.
The frv unique logic can be moved to a dedicated include and merged
in the common configure since the flag has been scoped to the arch.
|
|
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.
|
|
Now that the model logic has been migrated into the runtime, there's
nothing specific in the bfin configure code, so merge it into the
common one.
|
|
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.
|
|
The code is already clean, so sync this over from gdb warning.m4.
Also shuffle the order of the flags a bit to match the current gdb
warning.m4 code.
|
|
We have some code tripping this warning, but it depends on the gcc
version & optimization levels. We've added some hints to the code
so some versions of gcc work better, but still not all. Let's just
disable the warning like gdb does.
|
|
Move the unique library tests to the common code so we can delete
the erc32 configure logic entirely.
|
|
This reduces the unique logic in bfin/configure to make it easier to
(eventually) unify it entirely.
|
|
We rewrite srcdir in subdir Makefiles that we generate from the common
parent dir since it points to the parent dir. Since @srcdir@ can be a
variety of formats (relative & absolute), switch to @abs_srcdir@ which
is a lot easier to adjust. Our use of srcdir in here should handle it.
|
|
Move the unique configure flag to acinclude.m4 so the common code
can include it, then delete the rx configure logic entirely.
|
|
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.
|
|
Move these options up to the common dir so we only test & export
them once across all ports.
|

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.
|
|
Move these options up to the common dir so we only test & export
them once across all ports. It makes it available to targets that
aren't cgen-based, but those will just ignore the settings, so it
shouldn't be an issue.
|
|
This will allow us to build the common code with the same inline
settings as the arch subdirs, and only do the test once.
|
|
Only one arch uses this currently, but others could too. By moving
it up to the common checks, it'll also let us simplify the moxie code
significantly.
|
|
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.
|
|
As we merge settings from subdirs into the common configure, we
sometimes need to keep the settings working in both dirs. Create
a makefile fragment to pass them down so we don't have to run the
checks twice. For now, the file is empty, but we'll start moving
logic in shortly.
|
|
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 GDB's silent-rules.mk to make some rules silent by default. These
rules cover most of what is built in sim/.
gdb/ChangeLog:
* silent-rules.mk (ECHO_CCLD, ECHO_AR, ECHO_RANLIB): New.
sim/ChangeLog:
* common/Make-common.in (COMPILE, libsim.a, run$(EXEEXT),
gentmap.o, gentmap): Make rules silent.

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.
|
|
This fixes remaking of these files and avoids unnecessary rebuilds.
Also add both to `make clean` to match other stamp files.
|
|
We only do the common code as automake simplifies the logic.
|
|
Since this file does not rely on any port-specific settings, move it
up to building as part of the common step so we only do it once in a
multibuild.
|
|
Now that gnulib provides this, assume it exists.

Currently, the sim-config module will abort if alignment settings
haven't been specified by the port's configure.ac. This is a bit
weird when we've allowed SIM_AC_OPTION_ALIGNMENT to seem like it's
optional to use. Thus everyone invokes it.
There are 4 alignment settings, but really only 2 matters: strict
and nonstrict. The "mixed" setting is just the default ("unset"),
and "forced" isn't used directly by anyone (it's available as a
runtime option for some ports).
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, then the
build won't work (see above as if SIM_AC_OPTION_ALIGNMENT wasn't
called). If default settings are provided, then that is used, but
we allow the user to override at runtime. Otherwise, the "wire"
settings are used and user runtime options to change are ignored.
Most ports specify a default, or set the "wire" to nonstrict. A
few set "wire" to strict, but it's not clear that's necessary as
it doesn't make the code behavior, by default, any different. It
might make things a little faster, but we should provide the user
the choice of the compromises to make: force a specific mode at
compile time for faster runtime, or allow the choice at runtime.
More likely it seems like an oversight when these ports were
initially created, and/or copied & pasted from existing ports.
With all that backstory, let's get to what this commit does.
First kill off the idea of a compile-time default alignment and
set it to nonstrict in the common code. For any ports that want
strict alignment by default, that code is moved to sim_open while
initializing the sim. That means WITH_DEFAULT_ALIGNMENT can be
completely removed.
Moving the default alignment to the runtime also allows removal
of setting the "wire" settings at configure time. Which allows
removing of all arguments to SIM_AC_OPTION_ALIGNMENT and moving
that call to common code.
The macro logic can be reworked to not pass WITH_ALIGNMENT as -D
CPPFLAG and instead move it to config.h.
All of these taken together mean we can hoist the macro up to the
top level and share it among all sims so behavior is consistent
among all the ports.

|
Move these options up to the common dir so we only test & export
them once across all ports. The AC_INIT macro does a lot of the
heavy lifting already which allows further simplification.
|
|
Move these options up to the common dir so we only test & export
them once across all ports.
The ppc code needs a little extra care with its trace settings as
it's not exactly the same API as the common code. The other knobs
are the same though.
|
|
This follows existing organizational structure with one configure option
per m4 file, and will make it easier to move to the common configure dir.
|
|
Since ppc now shares a config.h with the top-level, move all of its
relevant settings up a level. The ppc port tests a lot more funcs,
but that's because its syscall emulation is a lot more complete.
We'll probably utilize some of these in the common code too.
|
|
Move the --sim-enable-environment option up to the common dir so we
only test & export it once across all ports.
|
|
Move the --sim-enable-assert option up to the common dir so we only
test & export it once across all ports.
|
|
Move the various platform tests up a level to avoid duplication
across the ports. When building multiple versions, this speeds
things up a bit.
For now we move the obvious stuff up a level, but we don't turn
own the config.h entirely just yet -- we still have some tests
related to libraries that need consideration.
|
|
This provides a space to generate things that we only need to build
once per-arch. Some day that will be all of common/, but for now,
we move the version.c management in.
|
|
We install libsim.a for people to link against, but haven't been
installing the header files to for its API. Export them!
|
|
|
|
The gdb/callback.h & gdb/remote-sim.h headers have nothing to do with
gdb and are really definitions for the libsim API under the sim/ tree.
While gdb uses those headers as a client, it's not specific to it. So
create a new sim/ namespace and move the headers there.
