RESOLVE is an extension of the existing armlink --unresolved command-line option. The difference is that --unresolved enables all undefined references to match one single definition, whereas RESOLVE enables more specific matching of references to symbols.

The undefined references are removed from the output symbol table.

RESOLVE works when performing partial-linking and when linking normally.

You might have two files file1.c and file2.c, as shown in the following example:

file1.c

extern int foo;
extern void MP3_Init(void);
extern void MP3_Play(void);

int main(void)
{
  int x = foo + 1;
  MP3_Init();
  MP3_Play();
  return x;
}


file2.c:

int foobar;
void MyMP3_Init()
{
}
void MyMP3_Play()
{
}

Create a steering file, ed.txt, containing the line:

RESOLVE MP3* AS MyMP3*.

Enter the following command:

armlink file1.o file2.o --edit ed.txt --unresolved foobar

This command has the following effects:
