Subject: [PATCH 15/22] perf tools: Compile dwarf-regs.c if CONFIG_BPF_PROLOGUE is on
Date: Thu, 8 Oct 2015 08:29:37 +0000 [thread overview]
Message-ID: <1444292984-13135-16-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1444292984-13135-1-git-send-email-wangnan0@huawei.com>
regs_query_register_offset() in dwarf-regs.c is required by BPF prologue.
Make it be compiled if CONFIG_BPF_PROLOGUE is on to avoid building failure
when CONFIG_BPF_PROLOGUE is on but CONFIG_DWARF is not set.
