Web4 apr 2024 · So getting the address pc-relative via adrp is the way to go. If you want the address itself, you would want adr_l.If you use ldr_l then you are actually loading from the address, in which case zero would be a reasonable result to expect since mydebug2 is not initialized with anything. Also the = is incorrect here. Try adr_l x28, mydebug2 / add x28, … Web17 apr 2024 · adrp x2, .LANCHOR0 ; .LANCHOR0是个——一个大小为4KB的页的基址，指令的作用就是将该页的基址存到寄存器x2中; 示例2： adrp x0, l_.str @PAGE ; 将符号l.str所在的page基址读入x0 add x0, x0, l_.str @PAGEOFF ; x0 = x0 + l.str所在page中的偏移量 bai van mieu ta cay bang
