adrp 页基地址指令（address of page), 用于计算基于当前 PC 的页基地址

adrp x0, #_g@PAGE    # 将变量 _g 所在的 4KB 大小页的 基地址，读入 x0 寄存器

cmp w0, #10 # 比较 w0 和 10

beqz s0, 1f Expands to beq s0, x0, 1f jump to label 1f if s0 == x0. Note that label 1f means to go to numeric label 1 FORWARD of the given position whose opposite is label 1b meaning to go to numeric label 1 BACKWARD of the given position.
csrrw t3, CSR_SSCRATCH, a0 Write the value in the csr register CSR_SSCRATCH to t3 register and write the value in a0 back to CSR_SSCRATCH
jal purgatory Expands to jal x1, purgatory and unconditionally jump to function purgatory() and write PC+4 into x1 (return address) register
jal t0, .Lbyte_copy_until_aligned_forward Write PC+4 into register t0 and unconditionally jump to label .Lbyte_copy_until_aligned_forward.
jalr s0 Expands to jalr x1, s0, 0 meaning the target address to jump to is s0 + 0 and write PC+4 into x1 (return address) register

AFAICT	As far as I can tell	个人认为
