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 a new header which only
this port will include.
|
|
The xxx-desc.h header file already includes this, and it's how the
other cgen ports are getting it, so drop it from these two.
|
|
The common sim headers should define these for us already, so there's
no need for the ppc header to set them up.
|
|
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.
|
|
Nothing compiles or references this, so punt it.
|
|
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.
|
|
Nothing actually uses these, so punt them. Some of the ports are
using local "word" types, but we'll clean those up in a follow up.
|
|
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.
|
|
The latter type matches the address size configured for this sim.
Also take the opportunity to simplify printf logic by leveraging
PRI* macros.

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.
|
|
Since the msb value is always defined as the wordsize-1, stop
hardcoding that value directly, and use a CPP value instead.
|
|
We want to kill off mips/configure entirely. Move this small part
out now to get started.
|
|
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.
|
|
In order to compile arch objects from the top-level, we need to
generate the hw-config.h header, so move that logic up to the top
level first.
|
|
We need these in the top-level to generate libsim.a, but also in the
subdirs to generate hw-config.h. Move it to the local.mk, and pass
it down when running recursive make. This avoids duplication, and
makes it available to both. We can simplify this once we move the
various steps up to the top-level too.
|
|
In order to create libsim.a in the common dir, we need the list of
objects for each target. To avoid duplicating the list with the
recursive make in each port, pass it down as a variable. This is
a temporary hack until the top-level creates libsim.a for ports.
|
|
Now that all ports have migrated to the new framework, drop support
for the old sim_cpu_base layout. There's a lot of noise here, so
it's been split into a dedicated commit.
|
|
All ports should be migrated now. Drop the SIM_HAVE_COMMON_SIM_CPU
knob and require it be used everywhere now.

The cpu.h change is in generated cgen code, but that has been sent
upstream too, so the next regen should include it automatically.

The cpu*.h changes are in generated cgen code, but that has been sent

Some common cgen code changes to allow cgen ports to invert their
sim_cpu storage one-by-one.
