There's no need for these settings to be in sim-main.h which is shared
with common/ sim code, so drop the d10v_sim.h include and move it to
the few files that actually need it.
Also rename the file to standardize it a bit better with other ports.
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.
Also migrate off the sim-specific unsignedXX types.
The defs.h header will take care of including the various config.h
headers. For now, it's just config.h, but we'll add more when we
integrate gnulib in.
This header should be used instead of config.h, and should be the
first include in every .c file. We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h. We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way. Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.
The compiler should produce reasonable code here in general, so punt the
various arch checks and bswap defines. This code will eventually go away
entirely when we convert it to the common memory code.
By itself, this commit doesn't really change anything. It lays the
groundwork for using the cpu state in follow up commits, both for
engine state and for cpu state. Splitting things up this way so it
is easier to see how things have changed.
