[Bug gold/11855] New: GOLD: PROVIDE: does not provide symbols only referenced in linker script

[nickc at redhat dot com]

Hi Guys,

  I have encountered a discrepancy between GNU LD and GOLD with regard to the
PROVIDE keyword.  If the provided symbol is not referenced in an input object
file then GOLD will not define it, even if it is referenced elsewhere in the
linker script.

  To reproduce follow these steps:

  % touch empty.c
  % gcc -c empty.c
  % cat <<EOF >provide.ld
  SECTIONS
  {
        PROVIDE (foo = 0);

        .bar :
        {
        LONG (foo);
        }
  }
  EOF

  % ld -T provide.ld empty.o
  % gold -T provide.ld empty.o
  gold: error: undefined symbol 'foo' referenced in expression

Cheers
  Nick
