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.

These are almost entirely unused. For the very few places using them,
replace with explicit signed types. This matches what was done in the
common sim code.
The regex it uses does not like so many leading spaces which causes
it to think the files lack copyright. Trim them down so the script
can find & update them accordingly.
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.
These are just using the default behavior for the 3rd arg, so drop
it to make it more clear. This also makes them match all other
ports that only use the first 2 arguments.
The header shuffling in here broke the workaround for gnulib defining
"open". Move it back before the sim-specific includes to fix. This
is because the callback struct in the headers has an "open" member and
this file tries to call that.
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.
We're including system headers after local headers in a bunch of
places, but this leads to conflicts when our local headers happen
to define symbols that show up in the system headers.
Use the more standard order of:
* config.h (via defs.h)
* system headers
* local library headers (e.g. bfd & libiberty)
* sim specific headers
Running frv's allinsn in serial is quite slow due to the sheer number
of tests it contains. By splitting it up and running in parallel, the
execution time on my system goes from ~100sec to ~60sec.
We'll rely on the toolchain probing to determine whether each arch's
tests can be run rather the current configure target. This allows
testing all of the ports in a multitarget configuration.
For now, we don't reformat the files entirely to make it easier to
review, and in case we need to make adjustments. Once this feels
like it's stable, we can flatten the code a bit by removing the if
statement entirely.
Break up the dejagnu logic so that we can parallelize the testsuite.
This takes a page from gcc & gdb where each .exp is run in isolation
instead of in serial.
For most targets, this doesn't make much of a difference as they only
have a single .exp. A few (like cris & frv) have multiple .exp though
and will see a bit of a speed up.
The real gain is when testing a multitarget build. This way we can
run all the targets in parallel and cut the execution time a bit.
On my system, it goes from ~155sec to ~100sec.
We can gain further speedups by splitting up some of the larger .exp
files into smaller groups. We'll do that in a followup though.
Leverage the new per-port toolchain settings to initialize the env
for eeach set of tests. This allows us to run all the tests in a
multitarget build if the user sets up the vars. If they don't, we
can still skip all the tests.
Gas does not support multitarget builds -- it still only supports
a single input & output format. ld is a bit better, but requires
manual flags to select the right output. This makes it impossible
to run the complete testsuite in a multitarget build.
To address this limitation, create a suite of FOR_TARGET variables
so these can be set to precompiled as & ld programs. It requires
a bit of setup ahead of time, but it's a one-time cost, and makes
running the full testsuite at once much easier.
Some of the core sim headers rely on the SIM_AC_OPTION_BITSIZE macro
which can change the size of core types. Since these haven't been
unified across ports, add checks to make sure they aren't accidentally
included when building for all ports. This caught the sim-load file
using poisoned headers that it didn't actually need.
Now that we've unified all the syscall tables, this file does not rely
on any port-specific settings, so move it up to building as part of the
common step so we only do it once in a multibuild.
Now that all ports have switched to target-newlib-* files, there's
no need for these files & generating things at build time. So punt
the logic and make target-newlib-syscall a hard requirement.
Use the new target-newlib-syscall module. This is needed to merge all
the architectures into a single build, and mcore has a custom syscall
table for its newlib/libgloss port.
Use the new target-newlib-syscall module. This is needed to merge all

Use the new target-newlib-syscall module. This is needed to merge all

This allows cleaning up the syscall ifdef logic. We know these will
always exist now.

Use the new target-newlib-syscall.h to provide the target syscall
defines. These code paths are written specifically for the newlib
ABI rather than being generalized, so switching them to the defines
rather than trying to go through the dynamic callback conversion
seems like the best trade-off for now. Might have to reconsider
this in the future.
Like we just did for pulling out the errno map, pull out the syscall
maps into a dedicated common file. Most newlib ports are using the
same syscall map, but not all, which means we have to do a bit more
work to migrate.
This commit adds the maps and switches the ports using the common
default syscall table over to it. Ports using unique syscall tables
are still using the old targ-map.c logic.
Switching common ports over is easy by checking NL_TARGET, but the
ppc code needs a bit more cleanup here hence its larger diff.
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.
