可以使用Visual Studio通过ARM脚本运行C代码吗？

Question

so I have these two files, one is a .c and one is a .s . These are just test files so I can get the hang of working C with ARM scripts, but for the life of me I can't get them to work together. I was wondering if I could make this easier by using either Visual Studio or VS code (or any other IDE if y'all know).

Here's my code:

ARM

.global add2
add2:
    stmfd sp!, {v1-v6, lr}  @ 'standard' entry, save registers on the stack
    add a1, a1, a2          @ do the addition requested
    ldmfd sp!, {v1-v6, pc}

C

#include <stdio.h> /* standard input and output */
#include <stdlib.h> /* standard library */
extern int add2(int i, int j); /* tell the compiler that the routine is not defined here */
int main(int argc, char * argv[]) /* entry point to the program */
{
    int i, j; /* declare the variable types */
    int answer;
    i = 5; /* give the variables values */
    j = 20;
    answer = add2(i, j); /* call the assembly language routine */
    printf("result is : %d\n", answer); /* print out the answer */
    exit(0); /* leave the driver program */
}

Currently the weird java program I've been using to link them is giving me the error

"D:\\Joe\\College Stuff\\CS 252\\add.s:1: Error: bad instruction ` .global add2'"

Any help would be appreciated

Answer 1

To fix this error, configure your editor to not insert a BOM (byte order mark) at the beginning of the file. You might be able to do this by selecting “save as” and then selecting a different encoding (eg “ASCII” or “UTF-8 no BOM” or something like this). If you could tell us what editor you used to create the ARM assembly file, I could provide you with more specific help.

For future people who come across this, no , you cannot run ARM scripts with C from visual studio. One way of doing it though is from the command line, which I found out from this question:
