However, those are not. Enable them by simply copying the perf optimization level. It can be expanded later if we want to support debug builds, etc. Signed-off-by: Borislav Petkov <bp@xxxxxxx> Reported-by: Jiri Olsa <jolsa@xxxxxxxxxx> Link: http://lkml.kernel.org/r/1362338733-8718-1-git-send-email-bp@xxxxxxxxx Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> --- tools/lib/lk/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/lib/lk/Makefile b/tools/lib/lk/Makefile index 8cf576f..926cbf3 100644 --- a/tools/lib/lk/Makefile +++ b/tools/lib/lk/Makefile @@ -10,7 +10,7 @@ LIB_OBJS += $(OUTPUT)debugfs.o LIBFILE = liblk.a -CFLAGS = -ggdb3 -Wall -Wextra -std=gnu99 -Werror $(CFLAGS_OPTIMIZE) -D_FORTIFY_SOURCE=2 $(EXTRA_WARNINGS) $(EXTRA_CFLAGS) -fPIC +CFLAGS = -ggdb3 -Wall -Wextra -std=gnu99 -Werror -O6 -D_FORTIFY_SOURCE=2 $(EXTRA_WARNINGS) $(EXTRA_CFLAGS) -fPIC EXTLIBS = -lpthread -lrt -lelf -lm ALL_CFLAGS = $(CFLAGS) $(BASIC_CFLAGS) -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 ALL_LDFLAGS = $(LDFLAGS) -- To unsubscribe from this list: send the line "unsubscribe linux-tip-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
