From 97db62062ac76e314c8bda4dc5b63f0ea906d15f Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 31 Aug 2015 21:39:44 +0300 Subject: [PATCH] perf tools: Fix build on powerpc broken by pt/bts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is theoretically possible to process perf.data files created on x86 and that contain Intel PT or Intel BTS data, on any other architecture, which is why it is possible for there to be build errors on powerpc caused by pt/bts. The errors were: util/intel-pt-decoder/intel-pt-insn-decoder.c: In function ‘intel_pt_insn_decoder’: util/intel-pt-decoder/intel-pt-insn-decoder.c:138:3: error: switch missing default case [-Werror=switch-default] switch (insn->immediate.nbytes) { ^ cc1: all warnings being treated as errors linux-acme.git/tools/perf/perf-obj/libperf.a(libperf-in.o): In function `intel_pt_synth_branch_sample': sources/linux-acme.git/tools/perf/util/intel-pt.c:871: undefined reference to `tsc_to_perf_time' linux-acme.git/tools/perf/perf-obj/libperf.a(libperf-in.o): In function `intel_pt_sample': sources/linux-acme.git/tools/perf/util/intel-pt.c:915: undefined reference to `tsc_to_perf_time' sources/linux-acme.git/tools/perf/util/intel-pt.c:962: undefined reference to `tsc_to_perf_time' linux-acme.git/tools/perf/perf-obj/libperf.a(libperf-in.o): In function `intel_pt_process_event': sources/linux-acme.git/tools/perf/util/intel-pt.c:1454: undefined reference to `perf_time_to_tsc' Signed-off-by: Adrian Hunter Cc: Jiri Olsa Cc: Sukadev Bhattiprolu Cc: Wang Nan Cc: Zefan Li Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1441046384-28663-1-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/Build | 1 + tools/perf/util/intel-pt-decoder/intel-pt-insn-decoder.c | 3 +++ 2 files changed, 4 insertions(+) diff --git a/tools/perf/util/Build b/tools/perf/util/Build index e912856cc4e5..e79e4522368a 100644 --- a/tools/perf/util/Build +++ b/tools/perf/util/Build @@ -75,6 +75,7 @@ libperf-y += record.o libperf-y += srcline.o libperf-y += data.o libperf-$(CONFIG_X86) += tsc.o +libperf-$(CONFIG_AUXTRACE) += tsc.o libperf-y += cloexec.o libperf-y += thread-stack.o libperf-$(CONFIG_AUXTRACE) += auxtrace.o diff --git a/tools/perf/util/intel-pt-decoder/intel-pt-insn-decoder.c b/tools/perf/util/intel-pt-decoder/intel-pt-insn-decoder.c index 9e4eb8fcd559..d23138c06665 100644 --- a/tools/perf/util/intel-pt-decoder/intel-pt-insn-decoder.c +++ b/tools/perf/util/intel-pt-decoder/intel-pt-insn-decoder.c @@ -146,6 +146,9 @@ static void intel_pt_insn_decoder(struct insn *insn, case 4: intel_pt_insn->rel = bswap_32(insn->immediate.value); break; + default: + intel_pt_insn->rel = 0; + break; } #else intel_pt_insn->rel = insn->immediate.value;
