WebNov 12, 2016 · 0. MCR and MRC don't exist in ARMv8. In ARMv7-A, system registers were typically accessed through coprocessor 15 (CP15) operations and accessed using MCR and MRC. However, AArch64 does not include support for coprocessors. In AArch64, system configuration is controlled through system registers, and accessed using MSR and MRS … WebInstruction ARM Thumb, 16-bit encoding Thumb, 32-bit encoding; BL label: ±32MB (All) ±4MB (All T) ±16MB (All T2) BL{cond} label: ±32MB (All)--- BL label and BLX label are an instruction pair.
