This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

This logic dates back to the original import, and seems to be for
handling systems where `rm -f` (i.e. no files) would error out.
None of that is relevant for us with current automake, so drop it.

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.
The mips code is a little more tricky than others because, for multi-run
targets, it generates the list of sources & objects on the fly in the
configure script.

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.
|
|
Update a few files that were missed, and revert the generated Automake
output that uses dates from Automake itself.

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.

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.

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.
|
|
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.
|
|
Now that there is no subdir configure script, we can clean up some
logic that was spread between the files.
