- Synopsis
-
Add upper immediate to pc/[pcc]
Note
|
CHERI extensions which use an alternative capability format may choose to redefine the handling of the immediate operand for this instruction in {cheri_cap_mode_name}. |

- {cheri_cap_mode_name} Description
-
Form a 32-bit offset from the 20-bit immediate filling the lowest 12 bits with zeros. Increment the address of the AUIPC instruction’s [pcc] by the 32-bit offset, then write the output capability to
cd
. The tag bit of the output capability is 0 if the incremented address is outside the [pcc]'s [section_cap_representable_check]. - {cheri_int_mode_name} Description
-
Form a 32-bit offset from the immediate, filling in the lowest 12 bits with zeros, adds this offset to the address of the AUIPC instruction, then places the result in register
rd
.
