I'm assuming that your question was intended to be something like, "what
are the sizes of the following C types for a 32-bit ARM using the GNU
toolset?" (As far as I can tell, the APCS doesn't specify type sizes
except to say that integral types occupy one word, except for long long,
which takes two. Floating-point types may use one, two, or three words.)
The one-line C program which answers this question reveals that char
uses one byte; short uses two; int, long, and float each take four; and
double needs eight.
