We used to be able to dump class layouts in WebKit frameworks:
% /usr/bin/python3 ./Tools/Scripts/dump-class-layout -b WebKitBuild -c Release
JavaScriptCore CodeBlock
Now, we can also dump class layouts in static libraries as well e.g.
% /usr/bin/python3 ./Tools/Scripts/dump-class-layout -b WebKitBuild -c Release
libJavaScriptCoreTools.a Corpse::Snapshot
Or more conveniently, we can do so by specifying the path to the binary file:
% /usr/bin/python3 ./Tools/Scripts/dump-class-layout
WebKitBuild/Release/libJavaScriptCoreTools.a Corpse::Snapshot
./Tools/Scripts/dump-class-layout will now look for target binaries (of various
formats) to dump from in this order:
1. name + ".framework/" + name
2. "lib" + name + ".a"
3. name + ".a"
4. "lib" + name + ".dylib"
5. name + ".dylib",
6. name
First one found that is a valid file will be consulted for the class layout
info to dump.
