The assembler assumes a flat 32-bit memory space. You can use the expressions listed in the following table to specify the relocation of a 32-bit label.
| Expression | Represents |
|---|---|
| label | The offset from the address of the label to the base of its section, relocated by the section base address. It also is the PC-relative target of a branch or call. It is a 32-bit address. |
| label@l | The low 16-bits of the relocated address of the symbol. |
| label@h | The high 16-bits of the relocated address of the symbol. You can OR this with label@l to produce the full 32-bit relocated address. |
| label@ha | The adjusted high 16-bits of the relocated address of the symbol. You can add this to label@l to produce the full 32-bit relocated address. |
| label@sdax | For labels in a small data section, the offset from the base of the small data section to the label. This syntax is not allowed for labels in other sections. |
| label@got | For processors with a global offset table, the offset from the base of the global offset table to the 32-bit entry for label. |
