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=utf8 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 e912856..e79e452 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 9e4eb8f..d23138c 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; -- 2.7.4
