Ошибка: internal_relocation - не могу понять ошибку

Question

Так я получаю эту ошибку:

program.s:62: Error: internal_relocation (type: OFFSET_IMM) not fixed up

Вот мой код:

.global main 
.global printf 
.global fopen 
.global fclose 
.global fgetc 

main: 
    @ Open File 
    PUSH {R1} @ Push address of R1 onto stack 
    LDR R0, [R1, #0x04] @ Get argv[1] from stack to R0 
    LDR R1, =r @ Load address of file open format (read) 
    BL fopen @ Open file 
    LDR R1, =fin @ Load address of file in to R1 
    STR R0, [R1] @ Store contents of R1 into R0 

    @ Setup array 
    LDR R4, =ch_array @ Array address 
    MOV R3, #0 @ Array index 

    BL loopFile 
    BL printArray 

@ Loop through the file 
loopFile: 
    LDR R1, =fin @ Load R1 with address of file in 
    LDR R0, [R1] @ Load R0 with pointer? of R1 
    BL fgetc @ Get next character from file into R0? 
    CMP R0, #-1 @ Check for end of file 
    BEQ endl @ Close file 

    @ get index from character (fgetc) 
    /* 
     Assuming the base address is in R4 (my array), the ascii is in R0 
     from the file input into R0: increment the word in memory at 
     the address 'R4 + (R0 * 4)'. *4 because each word is 4 bytes. 
    */ 
    LSL R0, R0, #2 
    LDR R1, [R4, R0] 
    ADD R1, R1, #1 
    STR R1, [R4, R0] 

    B loopFile @ Run loop again 

@ Close the file 
endl: 
    LDR R1, =fin @ Load R1 with address of file in 
    LDR R0, [R1] @ Load R0 with pointer? of R1 
    BL fclose @ Close the file 

printArray: 
    CMP R3, #ARRAY_MAX @ while (i < ARRAY_MAX) 
    BEQ _exit @ Exit if max 

    @ Check if value of the array at index i where 
    @ (i = character number) is 0, if so then skip it 
    @ else print it 

    @ R3 counter of array 
    @ R4 array address 

    LDR R0, =printa @ Load print format 
    LDR R1, R3 @ Store character value (index of array) in R1 
    LDR R2, [R4, R3] @ Load count of index R3 
    CMP R2, #0 @ Check if count is 0 
    BEQ printArray @ If count is 0, skip 
    BL printf @ Else print 
    ADD R3, R3, #1 @ Increment R3 ('i') 
    B printArray @ Loop next iteration of array 

@ End program 
_exit: 
    MOV R7, #1 
    MOV R0, #0 
    SWI 0 

.data 
    .equ ARRAY_MAX, 255 
    ch_array: 
     .rept ARRAY_MAX @For all elements in array, repeat: 
     .word 0x00 @Initialize to 0 
     .endr @End repetition 
    fin: .word 0x00 
    printa: .asciz "%d : %d\n" 
    r:  .asciz "r" 
    space: .asciz " " 
    nl: .asciz "\n" 

Я не вижу, что ошибка может для этого. Когда я изменяю линию 62 до:

LDR R1, [R3] 

Это дает мне ошибку в сегментации. Есть идеи?

Спасибо!

Answer 1

Неправильный способ перемещения (копирования) значения одного регистра в другой регистр: LDR R1, R3.

Вы должны использовать MOV инструкции для этого: MOV R1, R3

Цель LDR инструкции заключается в л габаритная д данные из памяти.
