Directly invoking make coverage-report as a target results in an error because its prerequisites are missing, This patch adds the compile-test prerequisite, which is run only once each time the compile-report target is invoked. In practice, the developer may decide to review the coverage-report results without necessarily rerunning for this coverage-test, if it has already been run. Signed-off-by: Elia Pinto <gitter.spiros@xxxxxxxxx> --- This is the second version of the patch. With respect to the first version, we tried to eliminate the inefficient coverage-test invocation if the target is coverage-report, introducing a more useful invocation order Makefile | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/Makefile b/Makefile index e8aba291d7..eacdffd748 100644 --- a/Makefile +++ b/Makefile @@ -3378,6 +3378,8 @@ check-builtins:: .PHONY: coverage-untested-functions cover_db cover_db_html .PHONY: coverage-clean-results +coverage-test.file?=coverage-test.file + coverage: $(MAKE) coverage-test $(MAKE) coverage-untested-functions @@ -3389,6 +3391,7 @@ coverage-clean-results: $(RM) coverage-untested-functions $(RM) -r cover_db/ $(RM) -r cover_db_html/ + $(RM) -f $(coverage-test.file) coverage-clean: coverage-clean-results $(RM) $(addsuffix *.gcno,$(object_dirs)) @@ -3404,12 +3407,16 @@ coverage-test: coverage-clean-results coverage-compile $(MAKE) CFLAGS="$(COVERAGE_CFLAGS)" LDFLAGS="$(COVERAGE_LDFLAGS)" \ DEFAULT_TEST_TARGET=test -j1 test +$(coverage-test.file): + @make coverage-test + touch $(coverage-test.file) + coverage-prove: coverage-clean-results coverage-compile $(MAKE) CFLAGS="$(COVERAGE_CFLAGS)" LDFLAGS="$(COVERAGE_LDFLAGS)" \ DEFAULT_TEST_TARGET=prove GIT_PROVE_OPTS="$(GIT_PROVE_OPTS) -j1" \ -j1 test -coverage-report: +coverage-report: $(coverage-test.file) $(QUIET_GCOV)for dir in $(object_dirs); do \ $(GCOV) $(GCOVFLAGS) --object-directory=$$dir $$dir*.c || exit; \ done -- 2.35.1
