CVTP (to capability)

Convert pointer to capability offset from PCC derives a Capability Value from a 64-bit register and PCC, and writes the result to the destination Capability register.

CVTP <Cd>, <Xn>

integer d = UInt(Cd); integer n = UInt(Rn);

Assembler Symbols

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

<Xn>	Is the 64-bit name of the source general-purpose register, encoded in the "Rn" field.

Operation

CheckCapabilitiesEnabled(); Capability operand1 = PCC[]; bits(64) operand2 = X[n]; Capability result; if CCTLR[].PCCBO == '1' then result = CapSetOffset(operand1,operand2); else result = CapSetValue(operand1,operand2); if CapIsSealed(operand1) then C[d] = CapWithTagClear(result); else C[d] = result;
