Labels for PC-relative addresses

7.7 Labels for PC-relative addresses

A label can represent the PC value plus or minus the offset from the PC to the label. Use these labels as targets for branch instructions, or to access small items of data embedded in code sections.

You can define PC-relative labels using a label on an instruction or on one of the data definition directives.
You can also use the section name of an AREA directive as a label for PC-relative addresses. In this case the label points to the first byte of the specified AREA. ARM does not recommend using AREA names as branch targets.
