Currently, Link Time Optimization is only available for Java Virtual Machines compiled with gcc. Since the Java VM is the most performance critical part of the Java Platform for obvious reasons, it follows that optimized executables produced for Windows (as Visual C++ is currently the only compiler available for Windows as [JDK-8288293](https://bugs.openjdk.org/browse/JDK-8288293) is still under heavy development) would grant a significant performance boost for Java on Windows as a whole. Flags used for link time optimizations are set to make compiling with it enabled as fast as possible, to avoid the pitfall of very long compile times
Depends on [JDK-8304893](https://bugs.openjdk.org/browse/JDK-8304893) being integrated first, to prove that link time optimization is viable as an option ------------- Commit messages: - Add to task list - Create new job for link time optimized builds - Missing ifeq - Merge branch 'openjdk:master' into patch-7 - 8304930: Enable Link Time Optimization as an option for Visual C++ Changes: https://git.openjdk.org/jdk/pull/13280/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=13280&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8304930 Stats: 19 lines in 2 files changed: 18 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/13280.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/13280/head:pull/13280 PR: https://git.openjdk.org/jdk/pull/13280
