Subject: [PATCH v4 21/28] Add frame info check to DW_OP_reg operations
Date: Fri, 5 Nov 2021 11:38:42 +0000	[thread overview]
Message-ID: <20211105113849.118800-22-zoran.zaric@amd.com> (raw)
In-Reply-To: <20211105113849.118800-1-zoran.zaric@amd.com>

From: Zoran Zaric <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.
