Subject: [PATCH 25/30] Add frame info check to DW_OP_reg operations
Date: Mon, 7 Dec 2020 19:00:26 +0000 [thread overview]
Message-ID: <20201207190031.13341-26-Zoran.Zaric@amd.com> (raw)
In-Reply-To: <20201207190031.13341-1-Zoran.Zaric@amd.com>
After enabling location description to be on a DWARF stack, it is now
needed to check the frame context information validity when creating a
register location description.
gdb/ChangeLog:
* dwarf2/expr.c (dwarf_expr_context::execute_stack_op): Add
check_frame_info call for DW_OP_reg operations.
