Subject: [PATCH v3 02/26] objtool: Rename func_for_each_insn()
Date: Tue, 24 Mar 2020 16:31:15 +0100
Message-ID: <20200324160924.024341229@infradead.org> (raw)
In-Reply-To: <20200324153113.098167666@infradead.org>

There is func_for_each_insn() and func_for_each_insn_all(), the both
iterate the instructions, but the first uses symbol offset/length
while the second uses insn->func.

Rename func_for_each_insn() to sym_for_eac_insn() because it iterates
on symbol information.
