[WHLSL] The checker needs to resolve types for the anonymous variables in ReadModifyWrite expressions https://bugs.webkit.org/show_bug.cgi?id=198988 Reviewed by Dean Jackson and Myles C. Maxfield. Source/WebCore: This patch makes it so that the Checker assigns types to the internal variables in a read modify write expression. These were the only variables that didn't have types ascribed to them. This patch also does a fly by fix where we kept pointers to value types in a HashMap in the checker. This is wrong precisely when the HashMap gets resized. Instead, we now just store the value itself since we're just dealing with a simple Variant that wraps either an empty struct or an enum.

WebKit is a cross-platform web browser engine. On iOS and macOS, it powers Safari, Mail, iBooks, and many other applications.
Visit WebKit Feature Status page to see which Web API has been implemented, in development, or under consideration.
Once your bug is filed, you will receive email when it is updated at each stage in the bug life cycle. After the bug is considered fixed, you may be asked to download the latest nightly and confirm that the fix works for you.
On Windows, follow the instructions on our website.
Run the following command to clone WebKit's Git SVN repository:
git clone git://git.webkit.org/WebKit.git WebKit
git clone https://git.webkit.org/git/WebKit.git WebKit
If you want to be able to commit changes to the repository, or just want to check out branches that aren’t contained in WebKit.git, you will need track WebKit's Subversion repository. You can run the following command to configure this and other options of the new Git clone for WebKit development.
For information about this, and other aspects of using Git with WebKit, read the wiki page.
If you don‘t want to use Git, run the following command to check out WebKit’s Subversion repository:
svn checkout https://svn.webkit.org/repository/webkit/trunk WebKit
Install Xcode and its command line tools if you haven't done so already:
Run the following command to build a debug build with debugging symbols and assertions:
For performance testing, and other purposes, use
You can open
WebKit.xcworkspace to build and debug WebKit within Xcode.
If you don't use a custom build location in Xcode preferences, you have to update the workspace settings to use
WebKitBuild directory. In menu bar, choose File > Workspace Settings, then click the Advanced button, select “Custom”, “Relative to Workspace”, and enter
WebKitBuild for both Products and Intermediates.
The first time after you install a new Xcode, you will need to run the following command to enable Xcode to build command line tools for iOS Simulator:
Without this step, you will see the error message: “
target specifies product type ‘com.apple.product-type.tool’, but there’s no such product type for the ‘iphonesimulator’ platform.” when building target

Run the following command to build a debug build with debugging symbols and assertions for iOS:
Tools/Scripts/build-webkit --debug --ios-simulator
For production builds:
cmake -DPORT=GTK -DCMAKE_BUILD_TYPE=RelWithDebInfo -GNinja ninja sudo ninja install
For development builds:
Tools/gtk/install-dependencies Tools/Scripts/update-webkitgtk-libs Tools/Scripts/build-webkit --gtk --debug
For more information on building WebKitGTK+, see the wiki page.
For production builds:
cmake -DPORT=WPE -DCMAKE_BUILD_TYPE=RelWithDebInfo -GNinja ninja sudo ninja install
For development builds:
Tools/wpe/install-dependencies Tools/Scripts/update-webkitwpe-libs Tools/Scripts/build-webkit --wpe --debug
For building WebKit on Windows, see the wiki page.
Run the following command to launch Safari with your local build of WebKit:
run-safari script sets the
DYLD_FRAMEWORK_PATH environment variable to point to your build products, and then launches
DYLD_FRAMEWORK_PATH tells the system loader to prefer your build products over the frameworks installed in
To run other applications with your local build of WebKit, run the following command:
Run the following command to launch iOS simulator with your local build of WebKit:
run-safari --debug --ios-simulator
In both cases, if you have built release builds instead, use
--release instead of
If you have a development build, you can use the run-minibrowser script, e.g.:
run-minibrowser --debug --wpe
Pass one of
--wpe to indicate the port to use.
