Load LOAcquire Register Byte.
- Is the 32-bit name of the general-purpose register to be transferred.
- Is the 64-bit name of the general-purpose base register or stack pointer.
Supported in ARMv8.1 and later.
Load LOAcquire Register Byte loads a byte from memory, zero-extends it and writes it to a register. The instruction also has memory ordering semantics as described in Load LOAcquire, Store LORelease. For information about memory accesses, see Load/Store addressing modes in the ARM Architecture Reference Manual ARMv8, for ARMv8-A architecture profile.
