+% IDE support in the JDK
+
+## Introduction
+
+When you are familiar with building and testing the JDK, you may want to
+configure an IDE to work with the source code. The instructions differ a bit
+depending on whether you are interested in working with the native (C/C++) or
+the Java code.
+
+### IDE support for native code
+
+There are a few ways to generate IDE configuration for the native sources,
+depending on which IDE to use.
+
+#### Visual Studio Code
+
+The make system can generate a [Visual Studio Code](https://code.visualstudio.com)
+workspace that has C/C++ source indexing configured correctly, as well as
+launcher targets for tests and the Java launcher. After configuring, a workspace
+for the configuration can be generated using:
+
+```shell
+make vscode-project
+```
+
+This creates a file called `jdk.code-workspace` in the build output folder. The
+full location will be printed after the workspace has been generated. To use it,
+choose `File -> Open Workspace...` in Visual Studio Code.
+
+##### Alternative indexers
+
+The main `vscode-project` target configures the default C++ support in Visual
+Studio Code. There are also other source indexers that can be installed, that
+may provide additional features. It's currently possible to generate
+configuration for two such indexers, [clangd](https://clang.llvm.org/extra/clangd/)
+and [rtags](https://github.com/Andersbakken/rtags). These can be configured by
+appending the name of the indexer to the make target, such as:
+
+```shell
+make vscode-project-clangd
+```
+
+Additional instructions for configuring the given indexer will be displayed
+after the workspace has been generated.
+
+#### Visual Studio
+
+This section is a work in progress.
+
+```shell
+make ide-project
+```
+
+#### Compilation Database
+
+The make system can generate generic native code indexing support in the form of
+a [Compilation Database](https://clang.llvm.org/docs/JSONCompilationDatabase.html)
+that can be used by many different IDEs and source code indexers.
+
+```shell
+make compile-commands
+```
+
+It's also possible to generate the Compilation Database for the HotSpot source
+code only, which is a bit faster as it includes less information.
+
+```shell
+make compile-commands-hotspot
+```
+
+### IDE support for Java code
+
+This section is a work in progress.

+Subject: [PATCH 50/50] G1 Heap parallel iterate method "object_par_iterate" +
+ dcevm timers
+
+G1 Heap does not have parallel iterate method, that is usefull in dcevm
+iterate phase. According performance tests the parallel iteration is up
+~25% faster then serial iteration, ratio depends on the size of heap.
+Dcevm's timers did not make sense. Now, there are timers fo prologue,
+doit, gc itarate and full gc phases. Iterate+fullgc time make up most
+the total doit time.
