Intermediate representations are usually categorized according to where they fall between a high-level language like C, and machine code. IRs that are close to a high-level language are called high-level IRs, and irs that are close to assembly are called low-level IRs. For example, a high-level IR might preserve things like array subscripts or field accesses whereas a low-level ir converts those into explicit addresses and offsetsIntermediate representations are usually categorized according to where they fall between a high-level language like C, and machine code.
