Clang plugin that rewrites PostTask(_, NewRunnableMethod(...)) to PostTask(_, base::Bind(...));

tools/clang/BindMigrate/README.chromium

+This is a simple example demonstrating how to use clang's facility for
+providing AST consumers using a plugin.
+
+Build the plugin by running `make` in this directory.
+
+Once the plugin is built, you can run it using:
+--
+Linux:
+$ clang -cc1 -load ../../Debug+Asserts/lib/libBindMigrate.so -plugin bind-migrate some-input-file.cc
+
+Mac:
+$ clang -cc1 -load ../../Debug+Asserts/lib/libBindMigrate.dylib -plugin bind-migrate some-input-file.cc
+
+To use with gyp, do something like:
+
+GYP_DEFINES='clang=1 clang_load=/abs/path/to/libBindMigrate.dylib
+clang_add_plugin=bind-migrate' gclient runhooks
+
+then do a clobber build to run the plugin on all files.
