Yes, the diff itself sometimes gives hints as to what has changed, but it&#39;s not always correct. Think about when it modifies the start of a function, but the diffstat &#34;name&#34; shows the previous function, a correct marking, but not what is needed.<br/><br/>Is the correct answer really going to be &#34;compile the two versions and compare the AST&#34; or something like that? No &#34;diff library&#34; somewhere that &#34;knows&#34; how to parse C (and Rust) that can do this in a faster way? Surely I&#39;m missing something obvious here... 2026-04-06T10:21:26Z https://yabu.me/nevent1qqs0m870zpc2n6cyl5kch3kdyrq3wev96nz9gsuvgzlnqxdywvznftszyza88ut8dcdscc9hcqpyw8w8hmdjk0dy53kfkdxc787tgtja5r0lw36fjgm In a few minutes I get interviewed by Shuah Khan and might answer questions from the audience if we have time: <a href="https://www.linuxfoundation.org/webinars/lf-live-maintainer-series-my-life-as-a-linux-kernel-developer-and-maintainer-with-greg-kh-and-shuah-khan">https://www.linuxfoundation.org/webinars/lf-live-maintainer-series-my-life-as-a-linux-kernel-developer-and-maintainer-with-greg-kh-and-shuah-khan</a><br/><br/>It will be recorded for playback later as well.

The end result here for any C developer alone, is much better off for all of their help. 2025-02-14T15:36:34Z
