86 * INT64 64-bit (8 byte) signed value
87 *
88 * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
89 * compiler-dependent header(s) and were introduced because there is no common
90 * 64-bit integer type across the various compilation models, as shown in
91 * the table below.
92 *
93 * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit

107 * usually used for memory allocation, efficient loop counters, and array
