From: Andi Kleen <a...@linux.intel.com> Add autoprobing for the xed disassembler library.
Can be downloaded from https://github.com/intelxed/xed v2: Hide. Require XED=1 to enable. Add XED_DIR v3: Remove -lxed from probe all. Don't touch FEATURE_DISPLAY. v4: Move to FEATURE_FLAGS_BASIC Signed-off-by: Andi Kleen <a...@linux.intel.com> --- tools/build/Makefile.feature | 4 +++- tools/build/feature/Makefile | 6 +++++- tools/build/feature/test-all.c | 5 +++++ tools/build/feature/test-xed.c | 9 +++++++++ tools/perf/Makefile.config | 16 ++++++++++++++++ tools/perf/Makefile.perf | 3 +++ 6 files changed, 41 insertions(+), 2 deletions(-) create mode 100644 tools/build/feature/test-xed.c diff --git a/tools/build/Makefile.feature b/tools/build/Makefile.feature index e3fb5ecbdcb6..c5012b8a49fe 100644 --- a/tools/build/Makefile.feature +++ b/tools/build/Makefile.feature @@ -63,7 +63,8 @@ FEATURE_TESTS_BASIC := \ lzma \ get_cpuid \ bpf \ - sdt + sdt \ + xed # FEATURE_TESTS_BASIC + FEATURE_TESTS_EXTRA is the complete list # of all feature tests @@ -140,6 +141,7 @@ ifeq ($(feature-all), 1) $(call feature_check,compile-x32) $(call feature_check,bionic) $(call feature_check,libbabeltrace) + $(call feature_check,xed) else $(foreach feat,$(FEATURE_TESTS),$(call feature_check,$(feat))) endif diff --git a/tools/build/feature/Makefile b/tools/build/feature/Makefile index b564a2eea039..4f1aa82b867a 100644 --- a/tools/build/feature/Makefile +++ b/tools/build/feature/Makefile @@ -48,7 +48,8 @@ FILES= \ test-get_cpuid.bin \ test-sdt.bin \ test-cxx.bin \ - test-jvmti.bin + test-jvmti.bin \ + test-xed.bin FILES := $(addprefix $(OUTPUT),$(FILES)) @@ -123,6 +124,9 @@ $(OUTPUT)test-numa_num_possible_cpus.bin: $(OUTPUT)test-libunwind.bin: $(BUILD) -lelf +$(OUTPUT)test-xed.bin: + $(BUILD) -lxed + $(OUTPUT)test-libunwind-debug-frame.bin: $(BUILD) -lelf $(OUTPUT)test-libunwind-x86.bin: diff --git a/tools/build/feature/test-all.c b/tools/build/feature/test-all.c index 699e43627397..4a6dd1d1ff49 100644 --- a/tools/build/feature/test-all.c +++ b/tools/build/feature/test-all.c @@ -149,6 +149,10 @@ # include "test-sdt.c" #undef main +#define main main_test_xed +# include "test-xed.c" +#endif + int main(int argc, char *argv[]) { main_test_libpython(); @@ -183,6 +187,7 @@ int main(int argc, char *argv[]) main_test_bpf(); main_test_libcrypto(); main_test_sdt(); + main_test_xed(); return 0; } diff --git a/tools/build/feature/test-xed.c b/tools/build/feature/test-xed.c new file mode 100644 index 000000000000..ef9aebf1559d --- /dev/null +++ b/tools/build/feature/test-xed.c @@ -0,0 +1,9 @@ +#include <xed/xed-interface.h> +#include <xed/xed-decode.h> +#include <xed/xed-decoded-inst-api.h> + +int main(void) +{ + xed_tables_init(); + return 0; +} diff --git a/tools/perf/Makefile.config b/tools/perf/Makefile.config index 03cf947755b9..9996027e7a52 100644 --- a/tools/perf/Makefile.config +++ b/tools/perf/Makefile.config @@ -684,6 +684,22 @@ ifndef NO_ZLIB endif endif +ifdef XED + ifdef XED_DIR + FEATURE_CHECK_CFLAGS-xed := -I $(XED_DIR)/include + # override for lib64? + FEATURE_CHECK_LDFLAGS-xed := -L $(XED_DIR)/lib -lxed + else + FEATURE_CHECK_CFLAGS-xed := + FEATURE_CHECK_LDFLAGS-xed := -lxed + endif + $(call feature_check,xed) + ifeq ($(feature-xed), 1) + EXTLIBS += -lxed + $(call detected,CONFIG_XED) + endif +endif + ifndef NO_LZMA ifeq ($(feature-lzma), 1) CFLAGS += -DHAVE_LZMA_SUPPORT diff --git a/tools/perf/Makefile.perf b/tools/perf/Makefile.perf index 4da19b6ba94a..f6760309edd3 100644 --- a/tools/perf/Makefile.perf +++ b/tools/perf/Makefile.perf @@ -84,6 +84,9 @@ include ../scripts/utilities.mak # Define NO_SDT if you do not want to define SDT event in perf tools, # note that it doesn't disable SDT scanning support. # +# Define XED=1 to build WITH the XED disassembler for perf script +# Can also set XED_DIR=/path to set XED directory. +# # Define FEATURES_DUMP to provide features detection dump file # and bypass the feature detection # -- 2.9.3
