前回amberはビルドできたのですが、panamaはmakeでエラーになりました。
今回panamaもビルドしてVector APIを試すことができました。
結論
configureでオプションを付ける。つまり、エラーを無視しているだけである。
$ bash ./configure --with-extra-cflags="-Wno-error=deprecated-declarations -Werror=nonnull -Wno-undefined-var-template -Wno-error=mismatched-parameter-types -Wno-error=shift-negative-value" $ make
エラーを理解して直せればいいのですが、いかんせんnon-Javaな世界。どうすればいいかまったくわからず、エラーを無視するオプションをつけるというしょぼい手段です。
詳細
前回はこういうエラーが出ていました。

[-Werror,-Wundefined-var-template]とあるので、undefined-var-templateを無視するよう-Wno-undefined-var-templateをつけました。するとエラーがこうなりました。

これも-Wno-error=mismatched-parameter-typesをつけて無視しました。するとエラーがこうなりました。

shifting a negative signed value is undefinedで、負の値はシフト演算できないようです。
これも-Wno-error=shift-negative-valueをつけて無視しました。今度はビルドが成功しました。

Vector APIを試す
$ export JAVA_HOME=[panama]/build/macosx-x86_64-normal-server-release/jdk $ java -version openjdk version "9-internal" OpenJDK Runtime Environment (build 9-internal+0-adhoc.koichisakata.panama) OpenJDK 64-Bit Server VM (build 9-internal+0-adhoc.koichisakata.panama, mixed mode)
まだ9のままのようです。
$ jshell | JShellへようこそ -- バージョン9-internal | 概要については、次を入力してください: /help intro jshell> import jdk.incubator.vector.FloatVector; jshell> import jdk.incubator.vector.Vector; jshell> import jdk.incubator.vector.Shapes;
Vector APIインポートできてます。こちらからサンプルをとってきます。
jshell> public static void AddArrays (float [] left, float [] right, float [] res, int i) { ...> FloatVector.FloatSpecies<Shapes.S256Bit> species = (FloatVector.FloatSpecies<Shapes.S256Bit>) ...> Vector.speciesInstance (Float.class, Shapes.S_256_BIT); ...> FloatVector<Shapes.S256Bit> l = species.fromArray (left, i); ...> FloatVector<Shapes.S256Bit> r = species.fromArray (right, i); ...> FloatVector<Shapes.S256Bit> lr = l.add(r); ...> lr.intoArray (res, i); ...> } | 警告: | 修飾子'static' は、トップ・レベル宣言で使用できません。無視されます | public static void AddArrays (float [] left, float [] right, float [] res, int i) { | ^-----------^ | 次を作成しました: メソッド AddArrays(float [],float [],float [],int)
サンプルがstaticだったJShellに怒られましたが、そのまま突っ切ります。しかもメソッド名大文字始まり。
えーと、256ビットの演算なので、floatだと8つ（256 / 32）用意すればいい。
jshell> float[] left = new float[] {0.0F,1.0F,1.5F,2.0F,0.0F,1.0F,1.5F,2.0F} left ==> float[8] { 0.0, 1.0, 1.5, 2.0, 0.0, 1.0, 1.5, 2.0 } jshell> float[] right = new float[] {0.0F,1.0F,1.5F,2.0F,0.0F,1.0F,1.5F,2.0F} right ==> float[8] { 0.0, 1.0, 1.5, 2.0, 0.0, 1.0, 1.5, 2.0 } jshell> float[] res = new float[8] res ==> float[8] { 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 } jshell> AddArrays(left, right, res, 0) jshell> System.out.println(Arrays.toString(res)) [0.0, 2.0, 3.0, 4.0, 0.0, 2.0, 3.0, 4.0]
配列同士で添字が同じものを足し算するのと同じ結果（実際はSIMDで複数の演算を一括で実施）なので、これで合っています。
今までエラーが出るとビルドを諦めていましたが、ここまでできれば今後エラーが出てもビルド自体はできそうです（エラーを無視している点は問題ですが）。
