Move it into read-only data sections to avoid constructing them on the
stack at runtime.
|
|
Remove duplicate nested variable declarations, rename some to avoid
confusion when the type is different or the original value should be
retained, and fix some weirdness with nested enums in structs.
|
|
Replace some fall through comments with the attribute.

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.
