Hi Taras,

  [You did not mention which target architecture(s) you are interested in, so I
have just tested the following on an x86 host].

  There should be no need to add a new command line option to the linker. 
Instead you can make use of the existing linker script facilities.  Try this:

  % cat align_bss.ld
  . = ALIGN (CONSTANT (MAXPAGESIZE));
  INSERT BEFORE .bss;

Then just add "-Wl,-Talign_bss.ld" to the firefox final link command line.

Cheers
  Nick

Is there also a way to page-pad .data ld.so zeros end of .data to end of 
mmaping.
