bits in otp source
** Data types:
226 **
227 ** Eterm: A tagged erlang term (possibly 64 bits)
228 ** BeamInstr: A beam code instruction unit, possibly larger than Eterm, not smaller.
229 ** UInt: An unsigned integer exactly as large as an Eterm.
230 ** SInt: A signed integer exactly as large as an eterm and therefor large
231 ** enough to hold the return value of the signed_val() macro.
232 ** UWord: An unsigned integer at least as large as a void * and also as large
233 ** or larger than an Eterm
234 ** SWord: A signed integer at least as large as a void * and also as large
