* ax-gdb.c.c (gen_expr) <UNOP_MEMVAL>: Handle value kinds other
than axs_rvalue.
2011-02-16 Pedro Alves <pedro@codesourcery.com>
gdb/testsuite/
* collection.c (globalarr3): New global.
(main): Initialize it before collecting, and and clear it
afterwards.
* collection.exp (gdb_collect_globals_test): Test collecting with
'{type} addr', where the addr expression is not an rvalue.
