The objects are still compiled in the subdir, but the creation of the
archive itself is in the top-level. This is a required step before we
can move compilation itself up, and makes it easier to review.
The downside is that each object compile is a recursive make instead of
a single one. On my 4 core system, it adds ~100msec to the build per
port, so it's not great, but it shouldn't be a big deal. This will go
away of course once the top-level compiles objects.

Nothing uses this hook anymore, so punt it. It was largely used to
track generated files (which we do in the top-level now) and extra
header files (which we use automake depgen for now).
|
|
Add rules for tracking generated subdir modules.c files. This doesn't
actually generate the file from the top-level, but allows us to add
rules that need to be ordered wrt it. Once those changes land, we can
rework this to actually generate from the top-level.
This currently builds off of the objects that go into the libsim.a as
we don't build those from the top-level either. Once we migrate that
up, we can switch this to the source files directly. It's a bit hacky
overall, but makes it easier to migrate things in smaller chunks, and
we aren't going to keep this logic long term.

The multirun generation mode is a bit of a mess as generated run files
depend on generate igen files, all with unknown names ahead of time.
In the multirun mode, be lazy and declare all of these generated source
files as built sources so they'll be created early on.

This commit moves getopt declaration checker originally in sim/
configure.ac; added in commit 340aa4f6872c ("sim: Check known getopt
definition existence") to sim/m4/sim_ac_platform.m4 (inside the
SIM_AC_PLATFORM macro).
It also regenerates configuration files using the maintainer mode.

On a bpf-*-* testsuite fails:
./ld/ld-new: warning: test has a LOAD segment with RWX permissions
Adjusting `--memory-size=10Mb' to the simulator bpf testsuite passes.
Tested on bpf-*-*:
Bug: https://sourceware.org/PR29954
sim/testsuite:
* bpf/allinsn.exp (SIMFLAGS_FOR_TARGET): Adjust sim flags.

Those files have changed by regenerating using the maintainer mode.
The first line of sim/ppc/pk.h have changed by an effect of the commit
319e41e83a40 ("sim: ppc: inline the sim-packages option").

This should have been part of the previous commit 80636a54bcfa2bca3dc8f
("sim: build: move generated headers to built sources"), but they were
missed because they're .c files effectively treated as .h files.
|
|
Rather than rely on SIM_SUBDIRS being set, add a dedicated variable
to track whether to enable the sim. While the current code works
fine, it won't work as we remove the recursive make logic (i.e. the
SIM_SUBDIRS variable).
|
|
All of these objects should be in libsim.a already, so don't link to
it too. In practice it never gets used, but no point in listing it.

Automake's automatic header deptracking has a bootstrap problem where
it can't detect generated headers when compiling. We've been handling
that by adding a custom SIM_ALL_RECURSIVE_DEPS variable, but that only
works when building objects recursively in subdirs. As we move those
out to the top-level, we don't have any recursive steps anymore. The
Automake approach is to declare those headers in BUILT_SOURCES.
This isn't completely foolproof as the Automake manual documents: it
only activates for `make all`, not `make foo.o`, but that shouldn't be
a huge limitation as it only affects the initial compile. After that,
rebuilds should work fine.
|
|
Now that everything has been hoisted to the top-level, we can delete
this unused logic.

The rules seem to generate the same output as existing subdir cgen
rules with cgen ports, so hopefully this should be correct. These
are the last set of codegen rules that we run in subdirs, so this
will help unblock killing off subdir builds entirely.
|
|
Rather than define our own hack for emitting an include statement,
use the existing Automake include variables. These have the nice
side-effect of being more portable.
|
|
Clean up includes a bit by making ports include bfd/ headers
explicitly. This matches other projects, and makes it more clear
where these headers are coming from.

Now that all run binaries are linked in the topdir, this subdir libs
variable isn't used anywhere, so punt it.
|
|
Since the port doesn't actually use this include, drop it.
No other port is doing this either.
|
|
Now that no ports use these common configure APIs, delete the logic
and remove it from the documentation.
|
|
Update a few files that were missed, and revert the generated Automake
output that uses dates from Automake itself.
|
|
These rules are the same as the common ones, so drop them to simplify.
|
|
These defines seem to have been added in anticipation of adding another
cpu port (IQ10BF?), but that was over 20 years ago, and that port has
yet to materialize. So drop these compile flags since they don't do
anything to the generated code. If another port ever shows up, it's
easy enough to readd things as needed.

This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

Now that all igen ports are in the top-level makefile, we don't need
this logic in any subdirs anymore, so clean it up.
|
|
Since these are the last mips igen rules, we can clean up a number of
bits in the local Makefile.in.

The naming in here has grown organically and is confusing to follow.
Originally there was only one set of rules for generating code from
the igen sources, so calling it "tmp-igen" and such made sense. But
when other multigen modes were added ("m16" & "multi") which also
used igen, it's not clear what's common igen and what's specific to
this generation mode. So rename the set of rules from "igen" to
"single" so it's easier to follow.
|
|
Since this rule is pretty simple, hoist it up to the common build.
|
|
The m16 & multi targets generate itable once even when all the other
modules are generated multiple times. The default igen target will
generate itable with everything else out of convenience. This means
flags are passed which don't affect the generated itable there.
We can unify the itable generation by making sure the right -F/-M
filter variables are passed down. Since there's already a dedicated
rule & variable in the multi build mode, generalize that and switch
the m16 & igen builds over too.
I spent a lot of time staring at this code, building for diff mips
targets, and exploring all the shell code paths. I think this is
safe, but only time (and users) will really tell.
|
|
This variable is only used to generate the itable files. In preparation
for merging the itable logic among all ports, rename "multi_flags" to a
more appropriate "igen_itable_flags" variable. There should be no real
chagnes here otherwise.
|
|
This code appears to be unused since it was first merged. When
micromips was enabled, it was via the "MULTI" config, not the
"MICROMIPS" config, and the multi configs have sep vars. Since
nothing sets SIM_MIPS_GEN=MICROMIPS in the config, all of this
should be unreachable, so punt it to simplify. Further, the
SIM_MIPS_MICROMIPS16_FLAGS & SIM_MIPS_MICROMIPS_FLAGS settings
rely on sim_mips_micromips{,16}_{filter,machine} variables that
are never set in the configure script.
|
|
All ports that need to clean things up at distclean time have moved
to the top-level build, so we can drop support for this hook.
|
|
This was missed when mips/configure was merged into the top-level.
|
|
While mips has respected sim_igen_smp at configure time (which was
always empty since it defaulted smp to off), no other igen port did.
Move this to a makefile variable and plumb it through the common
IGEN_RUN variable instead so everyone gets it by default. We also
clean up some redundant -N0 setting with multirun mips.
