Every file that igen outputs is then processed with the move-if-changed
shell script. This creates a lot of boilerplate in the build and not an
insignificant amount of build-time overhead. Move the simple "is the file
changed" logic into igen itself.
There's no need for these settings to be in sim-main.h which is shared
with common/ sim code, so move it all out to the existing or1k-sim.h.
Unfortunately, we can't yet drop the or1k-sim.h include from sim-main.h
as many of the generated CGEN files refer only to sim-main.h. We'll
have to improve the CGEN interface before we can make more progress,
but this is at least a minor improvement.

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.

We can also move the machs.h include out since the model logic was all
generalized from compile-time to runtime last year.

There's no need for these settings to be in sim-main.h which is shared

the few files that actually need it.
While we're here, drop redundant includes from sim-main.h:
* sim-config.h & sim-types.h included by sim-basics.h already
* sim-engine.h included by sim-base.h already
And move sim-options.h to the one file that needs it.

Move this out of the global sim-main.h and to the few files that
actually use functions from it. Only the cgen ports were pulling
this, so this makes cgen & non-cgen behave more the same.
The cgen-types.h header sets up types that are needed by cgen-defs.h,
so move the include out of sim-main.h and to that header. It might
be needed in other specific modules, but for now let's kick it out of
sim-main.h to make some progress. Things still build with just this.
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.
The bfd APIs are used only by sim-n-endian.h which is only included by
sim-endian.c, so move the bfd.h include there and out of sim-endian.h
which is included by many other modules.
Not all arches include this in sim-main.h, and the ones that do don't
actually use bfd defines in the sim-main.h header. Prune it to make
sim-main.h simpler so we can kill it off entirely in the future.
We add the include to the files that utilize e.g. bfd_vma though.
This is a 32-bit architecture with 32-bit registers, so replace the
custom "word" long int typedef with an explicit int32_t. This is
a correctness fix since long will be 64-bits on most 64-bit hosts.
This is a 32-bit architecture with 32-bit registers, so replace the
custom "word" int typedef with an explicit int32_t. Practically
speaking, this produces the same code, but it should hopefully make
it easier to merge common code in the future.
These variables are setting the same value as the defaults. Trim
this redundant logic to make it easier to see the real differences
so we can try to keep unifying cases.
Change the default (unhandled) mips64* targets to use the existing
mips64 multi-run build. It already handles the formats, we just
have to list the mips8000 bfd for it.
The existing mips64vr-* multi-run build already handles mips5000
targets, so reuse that for mips64vr5* targets too. This moves
more logic from build-time to runtime so we can have a single
binary that supports many targets.
We've been using SIM_ADDR which has always been 32-bit. This means
the upper 32-bit address range in 64-bit sims is inaccessible. Use
64-bit addresses all the time since we want the APIs to be stable
regardless of the active arch backend (which can be 32 or 64-bit).
The length is also 64-bit because it's completely feasible to have
a program that is larger than 4 GiB in size/image/runtime. Forcing
the caller to manually chunk those accesses up into 4 GiB at a time
doesn't seem useful to anyone.
Bug: https://sourceware.org/PR7504
Since SIM_ADDR is always 32-bit, it might truncate the address with
64-bit ELFs. Since we load that addr from the bfd, use the bfd_vma
type which matches the bfd_get_start_address API.
The existing mips64vr-* multi-run build already handles mips4300
targets, so reuse that for mips64vr43* targets too. This moves
more logic from build-time to runtime so we can have a single
binary that supports many targets.
We don't need to enforce larger target settings when the only thing
the sim should care about is the CPU target. So reduce most of the
target matches to only check the CPU.
This drops support for the --enable-sim-float configure option,
but it's not clear anyone ever actually used that. Eventually
we'll want this to be a runtime option anyways.
Don't assume that the default bfd that we configured for is the one
that is always active when running a program. We already have access
to the real runtime value, so use it directly. This simplifies the
code quite a bit, and will make it easier to support multiple mach's
in a single binary.
