ADRP

Form PC-relative address to 4KB page adds an immediate value that is shifted left by 12 bits, to the PC value to form a PC-relative address, with the bottom 12 bits masked out, and writes the result to the destination register.

Literal

ADRP <Xd>, <label>

integer d = UInt(Rd); boolean page = (op == '1'); bits(64) imm; imm =if page then imm = SignExtend(immhi:immlo:Zeros(12), 64);(12), 64); else imm =SignExtend(immhi:immlo, 64);

Assembler Symbols

<Xd>

Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field.

<label>

Is the program label whose 4KB page address is to be calculated. Its offset from the page address of this instruction, in the range +/-4GB, is encoded as "immhi:immlo" times 4096.

Operation

bits(64) base = PC[]; base<11:0> =if page then base<11:0> = Zeros(12); X[d] = base + imm;
