(Note: Reducing compiler warnings across all, but primarily LP64
platforms, is a long term objective.)
Reduce compiler warnings on LP64 platforms (macOS, Windows) and 32-bit
builds (Win32). Prefer 'size_t' for pointer arithmetic, array indexing
and extents; 'int' hasn't been used for these purposes for many years
and across many ANSI standards. N.B. that conversions from int or int32
to size_t cause the compiler to zero-extend the value, which is
inefficient.
Refactor printf() format modifiers into sim_printf_fmts.h. Add the
SIZE_T_FMT modifier for better portability, especially on LP64 platforms
where size_t is unsigned long and sizeof(size_t) > sizeof(int).
3B2: Fix known size_t printf() format.
* CMake build infrastructure
The squashed commit that builds and packages releases for the SIMH
simulator suite with CMake, version 3.14 or newer.
