Is it possible to find a certain binary code in the exe file?

Question

Chromium

Given: Chromium source code, configured build environment. Required - to determine how changes to a few lines of the Chromium source correspond to the Google Chrome binary (that Chrome is not really Chromium, I know, this is another difficulty). At the output, you need to find the bytes that need to be replaced, and make some kind of Chrome patching mechanism. That the digital signature will fly off - it does not matter, this is for personal use.
Any ideas? Is it really possible to do it at all?
PS I am very superficially familiar with C++ programming (I just know what and how to change), I am almost not familiar with development in Visual Studio, so please explain as "on your fingers" as possible.

Answer 1

In the general case, the problem is solved by building two binaries: from the original and modified code. Then you compare the results. But if the changes include adding / deleting code or conditional transitions, everything will float and the devil will break his leg there. And then IDA in hand and watch.
