a96c03e8cdcf123384319f312d0a08a7a760bb35 - tools build: Add test-reallocarray.c to test-all.c to fix the build

Thu, 14 Feb 2019 15:01:04 +0000

tools build: Add test-reallocarray.c to test-all.c to fix the buildWhen a test is in the FEATURE_TESTS_BASIC list in tools/build/Makefile.featuremust be added to tools/build/feature/test-all.c, because the successfullcompilation and linking of that test-all.bin file means that all thefeatures listed in FEATURE_TESTS_BASIC are present in the system, so wedon't have to go on feature by feature test building them.Since reallocarray() is expected to be present in modern systems, it hasa place in FEATURE_TESTS_BASIC, so that we speed up the build processbuilding just that file.For older systems, such as ubuntu:16.04 (build failure reported by JinYao) debian:8, and for the current flagship RHEL distro, RHEL7, thebuild will fail as test-all.bin (without test-reallocarray.c included)passes but reallocarray() isn't present, making the build fail with: CC /tmp/build/perf/libbpf.o MKDIR /tmp/build/perf/fs/ CC /tmp/build/perf/fs/tracing_path.o LD /tmp/build/perf/fd/libapi-in.o CC /tmp/build/perf/bpf.o libbpf.c: In function 'bpf_object__add_program': libbpf.c:367:10: error: implicit declaration of function 'reallocarray' [-Werror=implicit-function-declaration] progs = reallocarray(progs, nr_progs + 1, sizeof(progs[0]));
