pla

Prefixed Load Address (Pseudo)

pla RT, label

Pseudo-instruction for paddi with R=1. Loads the address of a label.

Details

The pla instruction is a pseudo-instruction that loads an address into a target register. It is equivalent to the addi instruction with a zero immediate value and a shift of zero.

Pseudocode Operation

RT <- PC + offset(label)

Programming Note

The pla instruction is used to load the address of a label into a register, effectively calculating the absolute address of the target. This is useful for setting up pointers or addresses dynamically. Ensure that the label is correctly defined and accessible in your code. The instruction operates at the same privilege level as the current execution context.

Example

pla r3, my_var
