> This PR contains Short Vector Math Library support related changes for > [JEP-414 Vector API (Second Incubator)](https://openjdk.java.net/jeps/414), > in preparation for when targeted. > > Intel Short Vector Math Library (SVML) based intrinsics in native x86 > assembly provide optimized implementation for Vector API transcendental and > trigonometric methods. > These methods are built into a separate library instead of being part of > libjvm.so or jvm.dll. > > The following changes are made: > The source for these methods is placed in the jdk.incubator.vector module > under src/jdk.incubator.vector/linux/native/libsvml and > src/jdk.incubator.vector/windows/native/libsvml. > The assembly source files are named as “*.S” and include files are named > as “*.S.inc”. > The corresponding build script is placed at > make/modules/jdk.incubator.vector/Lib.gmk. > Changes are made to build system to support dependency tracking for > assembly files with includes. > The built native libraries (libsvml.so/svml.dll) are placed in bin > directory of JDK on Windows and lib directory of JDK on Linux. > The C2 JIT uses the dll_load and dll_lookup to get the addresses of > optimized methods from this library. > > Build system changes and module library build scripts are contributed by > Magnus (magnus.ihse.bur...@oracle.com). > > Looking forward to your review and feedback. > > Performance: > Micro benchmark Base Optimized Unit Gain(Optimized/Base) > Double128Vector.ACOS 45.91 87.34 ops/ms 1.90 > Double128Vector.ASIN 45.06 92.36 ops/ms 2.05 >
