Ask for helping about LD linker

[jian]

Dear,

Excuse me,I don't know how to  remove unused functions and variable when linking ELF.

 

please let me know ASAP.

 

eg.

 

int main()

{

 

int i;

 

i= 5;

return i;

}

 

 

char tmpBuffer[5];

 

char *getTmpBuff()

{

return tmpBuffer;

}

 

char *getTmpBuff1()

{

return tmpBuffer;

}

 

char *getTmpBuff2()

{

return tmpBuffer;

}

how to discard the functions(getTmpBuff,getTmpBuff1,getTmpBuff2) when linking.

 

Best regards.
