From c6e3bf437184d41d885ba679eab0ddd43f95db56 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 26 Apr 2021 15:47:39 -0300 Subject: [PATCH] perf build: Defer printing detected features to the end of all feature checks We were doing it in tools/build/Makefile.feature, after running the feature checks, but then in tools/perf/Makefile.config we can call more feature checks when we notice that some feature check failed, like when libbfd wasn't detected and we add libraries to the LDFLAGS of its feature check to try again, etc. Acked-by: Jiri Olsa Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/Makefile.config | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/tools/perf/Makefile.config b/tools/perf/Makefile.config index 94e31fa75f42..0d6619064a83 100644 --- a/tools/perf/Makefile.config +++ b/tools/perf/Makefile.config @@ -299,6 +299,9 @@ ifneq ($(TCMALLOC),) endif ifeq ($(FEATURES_DUMP),) +# We will display at the end of this Makefile.config, using $(call feature_display_entries) +# As we may retry some feature detection here, see the disassembler-four-args case, for instance + FEATURE_DISPLAY_DEFERRED := 1 include $(srctree)/tools/build/Makefile.feature else include $(FEATURES_DUMP) @@ -1230,3 +1233,7 @@ $(call detected_var,PYTHON_EMBED_CCOPTS) # tests, see the block about libbfd, disassembler-four-args, for instance. $(shell rm -f $(FEATURE_DUMP_FILENAME)) $(foreach feat,$(FEATURE_TESTS),$(shell echo "$(call feature_assign,$(feat))" >> $(FEATURE_DUMP_FILENAME))) + +ifeq ($(feature_display),1) + $(call feature_display_entries) +endif
