Where:
Wn-
Is the 32-bit name of the first general-purpose source register.
Xn-
Is the 64-bit name of the first general-purpose source register.
imm-
Is a five bit unsigned immediate.
nzcv-
Is the flag bit specifier, an immediate in the range 0 to 15, giving the alternative state for the 4-bit NZCV condition flags.
cond-
Is one of the standard conditions.
Operation
Conditional Compare (immediate) sets the value of the condition flags to the result of the comparison of a register value and an immediate value if the condition is TRUE, and an immediate value otherwise.
flags = if , where cond then compare(Rn, #imm) else #nzcvRW or X.
