Hello,

The fix looks correct, but I'm starting to think that maybe the conditional should be inverted and instead list the architectures that actually use -m64? It seems a whole lot of them don't.

Magnus indicated he was working on a better solution when he put in the quick-fix check for Aarch64. Yes this should only add -m64 on compilers and platforms that support it.

I made a small patch to pass the configure: $ hg diff make/autoconf/flags.m4 diff -r 3acb379b8672 make/autoconf/flags.m4 --- a/make/autoconf/flags.m4 Thu Mar 22 08:09:51 2018 +0800 +++ b/make/autoconf/flags.m4 Thu Mar 22 12:55:00 2018 +0800 @@ -237,7 +237,11 @@ MACHINEFLAG="-q${OPENJDKTARGETCPUBITS}" elif test "x$TOOLCHAINTYPE" != xmicrosoft; then if test "x$OPENJDKTARGETCPU" != xaarch64 && -        test "x$OPENJDKTARGETCPU" != xarm; then +        test "x$OPENJDKTARGETCPU" != xarm && +        test "x$OPENJDKTARGETCPU" != xmips && +        test "x$OPENJDKTARGETCPU" != xmipsel && +        test "x$OPENJDKTARGETCPU" != xmips64 && +        test "x$OPENJDKTARGETCPU" != xmips64el; then MACHINEFLAG="-m${OPENJDKTARGETCPUBITS}" fi fi I think this is the same problem with bug 8199052 and 8199152. Could someone help to review the change? Thanks, Ao Qi
