translation problems. * ada-lang.c (ada_value_struct_elt): Change interface and handling of errors to avoid translation problem (and less than optimal error messages). (ada_value_tag, ada_tag_name_1, ada_tag_name_2, ada_evaluate_subexp): Use new interface to ada_value_struct_elt. * ada_lang.h (ada_value_struct_elt): Update declaration to new interface. * ChangeLog: remove reference to ada-tasks.c from entry of 2006-01-07.

definition, we represent it with an OP_VAR_VALUE, even though

it may turn out to be within a record aggregate. Aggregate
|
|
evaluation can use either OP_NAMEs or OP_VAR_VALUEs to get a
|
|
record field name, and can evaluate OP_VAR_VALUE normally to
|
|
get its value as an expression. Unfortunately, we lose out in
|
|
cases where X has multiple meanings and is part of an array
