[Bug middle-end/37170] New: [4.4 Regression]: gcc.dg/weak/weak-1.c

["hp at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

With 139231 this test passed.
With 139233 and on, I now see for cris-elf:

Running /tmp/hpautotest-gcc1/gcc/gcc/testsuite/gcc.dg/weak/weak.exp ...
FAIL: gcc.dg/weak/weak-1.c scan-assembler weak[^ \t]*[ \t]_?j

I see this regression in posted testresults from ia64 and powerpc64 too.

Apparently, this is caused by revision 139233 which appears to rely on
output_operand to catch all weaks, but the change to output_operand on July 21
to call assemble_external is incomplete and only works for targets where
variable references are always wrapped in exactly one MEM around a symbol_ref. 
(Missing cases of multiple mems, or where symbol_ref¨s aren't valid addresses
and offset references).

I'm testing a patch.
