--- Comment #6 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Answering my own question:
  https://gcc.gnu.org/onlinedocs/gccint/Types.html

INTEGER_TYPE

    Used to represent the various integral types, including char, short, in=
t,
long, and long long. This code is not used for enumeration types, nor for t=
he
bool type. The TYPE_PRECISION is the number of bits used in the representat=
ion,
represented as an unsigned int. (Note that in the general case this is not =
the
same value as TYPE_SIZE; suppose that there were a 24-bit integer type, but
that alignment requirements for the ABI required 32-bit alignment. Then,
TYPE_SIZE would be an INTEGER_CST for 32, while TYPE_PRECISION would be 24.)
The integer type is unsigned if TYPE_UNSIGNED holds; otherwise, it is signe=
d.=
