From 30433a3a52b951faab95944e0f8b9d33a1e322ce Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Mon, 16 Nov 2015 12:10:11 +0000 Subject: [PATCH] perf bpf: Compile dwarf-regs.c if CONFIG_BPF_PROLOGUE is on regs_query_register_offset() in dwarf-regs.c is required by BPF prologue. This patch compiles it if CONFIG_BPF_PROLOGUE is on to avoid build failure when CONFIG_BPF_PROLOGUE is on but CONFIG_DWARF is not set.
