Subject: [PATCH v3 08/17] Move read_mem to dwarf_expr_context
Date: Fri, 28 May 2021 16:46:39 +0100 [thread overview]
Message-ID: <20210528154648.60881-9-zoran.zaric@amd.com> (raw)
In-Reply-To: <20210528154648.60881-1-zoran.zaric@amd.com>
Following the idea of merging the evaluators, the read_mem method can
be moved from dwarf_expr_executor and dwarf_evaluate_loc_desc classes
to their base class dwarf_expr_context.
gdb/ChangeLog:
* dwarf2/expr.c (dwarf_expr_context::read_mem): Move from
dwarf_evaluate_loc_desc.
* dwarf2/frame.c (dwarf_expr_executor::read_mem): Remove
method.
* dwarf2/loc.c (dwarf_evaluate_loc_desc::read_mem): Move to
dwarf_expr_context.
