How to recompile only changed parts of chromium?

I built Chromium from the source code (ninja -C out/Debug chrome) and make sure it works. After I executed:

git pull
gclient sync
ninja -C out/Debug chrome

The build system actually starts to building all the parts of the project again. Is it possible to rebuild only the changed parts of chromium?

From the windows build instructions it lists this build parameter:

is_component_build = true - this uses more, smaller DLLs, and incremental linking.

Execute:

gn args out/WhateverYouWant

Add 

is_component_build = true

to the text file, save it, and close it.

For every build after the first it won't compile any components that you haven't changed.

Always do release build if you don't want to debug chrome browser.

Use ninja -C out/Release chrome to perform a release build. Debug build takes time in linking.

git pull updates your code and gclient sync syncs or sets the HEAD of the repo to the Last Known Good Revision(LKGR). Hence, no. of changed files plus no. of files which were dependent on that would be recompiled again.
