Subject: [PATCH 09/30] Inline get_reg_value method of dwarf_expr_context
Date: Mon,  7 Dec 2020 19:00:10 +0000	[thread overview]
Message-ID: <20201207190031.13341-10-Zoran.Zaric@amd.com> (raw)
In-Reply-To: <20201207190031.13341-1-Zoran.Zaric@amd.com>

The get_reg_value method is a small function that is only called once,
so it can be inlined to simplify the dwarf_expr_context class.

gdb/ChangeLog:

	* dwarf2/expr.c (dwarf_expr_context::get_reg_value): Remove
	method.
	(dwarf_expr_context::execute_stack_op): Inline get_reg_value
	method.
	* dwarf2/expr.h (dwarf_expr_context::get_reg_value): Remove
	method.
