There is no reason to duplicate and force this functionality in --enable-fuzzing. In the future, if more sanitizers are added to --enable-sanitizers, it might be impossible to build with both --enable-sanitizers and --enable-fuzzing, since not all sanitizers are compatible with libFuzzer. In that case, we could enable ASAN with --extra-cflags=3D"-fsanitize=3Daddress" Signed-off-by: Alexander Bulekov Message-Id: <20200706195534.14962-2-alxndr@bu.edu> Reviewed-by: Philippe Mathieu-Daud=C3=A9 Reviewed-by: Thomas Huth [thuth: Added missing $CFLAGS] Signed-off-by: Thomas Huth --- configure | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/configure b/configure index 33cee41f9c..4bd80ed507 100755 --- a/configure +++ b/configure @@ -6337,7 +6337,7 @@ fi # checks for fuzzer if test "$fuzzing" =3D "yes" ; then write_c_fuzzer_skeleton - if compile_prog "$CPU_CFLAGS -Werror -fsanitize=3Daddress,fuzzer" ""; th= en + if compile_prog "$CPU_CFLAGS -Werror -fsanitize=3Dfuzzer" ""; then have_fuzzer=3Dyes fi fi @@ -7893,11 +7893,11 @@ if test "$have_mlockall" =3D "yes" ; then fi if test "$fuzzing" =3D "yes" ; then if test "$have_fuzzer" =3D "yes"; then - FUZZ_LDFLAGS=3D" -fsanitize=3Daddress,fuzzer" - FUZZ_CFLAGS=3D" -fsanitize=3Daddress,fuzzer" - CFLAGS=3D"$CFLAGS -fsanitize=3Daddress,fuzzer-no-link" + FUZZ_LDFLAGS=3D" -fsanitize=3Dfuzzer" + FUZZ_CFLAGS=3D" -fsanitize=3Dfuzzer" + CFLAGS=3D"$CFLAGS -fsanitize=3Dfuzzer-no-link" else - error_exit "Your compiler doesn't support -fsanitize=3Daddress,fuzzer" + error_exit "Your compiler doesn't support -fsanitize=3Dfuzzer" exit 1 fi fi --=20 2.18.1
