ADR

Form PCC-relative address adds an immediate value to the PCC value to form a PCC-relative address, and writes the result to the destination register.

Assembler Symbols

<Cd>	Is the capability name of the destination register, encoded in the "Rd" field.

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

<label>

Is the program label whose address is to be calculated, in the range +/-1MB, encoded in "P:immhi:immlo".

Operation

if IsInC64() then Capability addr = PCC[]; C[d] = CapAdd(addr,imm); else bits (64) addr; if CCTLR[].PCCBO == '1' then addr = CapGetOffset(PCC[]); else addr = CapGetValue(PCC[]); X[d] = addr + imm;
