As both // relaxation and patching transform instructions very late in the // link there is a possibility of them both being simultaneously // applied. In this case the relaxed sequence is immune from the erratum so we // prefer to keep it. .text .balign 4096 .space 4096 - 8 .globl _start .type _start,@function _start: mrs x1, tpidr_el0 adrp x0, :gottprel:v ldr x1, [x0, #:gottprel_lo12:v] adrp x0, :gottprel:v ldr x1, [x0, #:gottprel_lo12:v] ret // CHECK: <_start>: // CHECK-NEXT: 211ff8: d53bd041 mrs x1, TPIDR_EL0 // CHECK-NEXT: 211ffc: d2a00000 movz x0, #0, lsl #16 // CHECK-NEXT: 212000: f2800201 movk x1, #16 // CHECK-NEXT: 212004: d2a00000 movz x0, #0, lsl #16 // CHECK-NEXT: 212008: f2800201 movk x1, #16 // CHECK-NEXT: 21200c: d65f03c0 ret .type v,@object .section .tbss,"awT",@nobits .globl v v: .word 0
