reloc against common symbols

[Vineet Sharma, Noida]

Hi, 
     Let me put my question in another way.
	
	Consider
 
 	 __y:		 .short  _x+28 //Reloc generated here
       		 .global _z
       		 .align  1
	_z:
       		 .short  1
        		.comm _x,120  //Symbol in Question

     Now when the coff_XXX_reloc() is called in coff-XXX.c, there the
"struct symbol" passed as an argument does not
     contain the address of the symbol(in this case _x) in the "value"
attribute of struct symbol.It contains the length(ie 	120) in this case.
		   While it is supposed to contain the address of the _x
symbol.

     So how do we calculate the address of the common symbols?


	Hope i have made my point clear, if still there are some ambiguity
or clarifications needed plz let me know.


With Regards
Vineet


	My problem is when the assembler encounter any common symbol like
".comm _x,120".
	So now when i need to fix any reloc against this symbol _x say
".short  _x+28".
      Now when the coff_XXX_reloc function is called the value attribute of
the symbol argument contains 120
	rather than

I'm afraid that I don't understand what you are saying.

If you want to report a bug, then follow the instructions in
binutils/README.
