There are also two different sizes for code models, 32–bit and 64–bit., which results in three code models for 32–bit code, and five code models for 64–bit code.
For 32–bit code, there are the following address modes:
32–bit absolute
13–bit PIC
32–bit PIC
For 64–bit code, there are the following address modes:
32–bit absolute
44–bit absolute
64–bit absolute
13–bit PIC
32–bit PIC
