Test bit and branch if zero to a label at a PC-relative offset, without affecting the condition flags, and with a hint that this is not a subroutine call or return.
Is a width specifier, and can be either
In assembler source code an
Xspecifier is always permitted, but a
Wspecifier is only permitted when the bit number is less than 32.
Is the number of the general-purpose register to be tested, in the range 0 to 30, or the name ZR (31).
Is the bit number to be tested, in the range 0 to 63.
Is the program label to be conditionally branched to. It is an offset from the address of this instruction, in the range ±32KB.
