Subject: [RFC][PATCH 02/16] objtool: Rename func_for_each_insn()
Date: Thu, 12 Mar 2020 14:41:09 +0100 [thread overview]
Message-ID: <20200312135041.524075934@infradead.org> (raw)
In-Reply-To: 20200312134107.700205216@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.
