Hi,

I have this C stuff:

void boot(void) __attribute__ ((section (".bootloader")));

and this part of the Makefile to set the address at link-time:

gcc [...]  -Wl,--section-start=.bootloader=0x1E000


Now I'd like to do the same in GNAT Ada.

I've tried:

   procedure Boot;
   pragma Machine_Attribute (Entity => Boot,
                             Attribute_Name => "section (.bootloader)"
                             );
   procedure Boot
   is
   begin   
      null;
   end;

and got this waring:

bootloader.adb:12: warning: `section (.bootloader)' attribute directive ignored


And 'objdump -h' doesn't print a .bootloader section :-(

You probably have to include the quotes around .bootloader also in the 
pragma in the Ada source, like this:

pragma Machine_Attribute (Entity => Boot,
                           Attribute_Name => "section ("".bootloader"")"
                           );

Sergey.

bootloader.adb:12: warning: `section (".bootloader")' attribute directive ignored


Is this supposed to work at all?
