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"")"
);

bootloader.adb:12: warning: `section (".bootloader")' attribute directive ignored
Is this supposed to work at all?
