| 2025-07-29 00:24:35 +0200 | <dolio> | I guess the answer to your implied question is that it's easier than graph isomorphism, because it's graph equality. It's only successful if the node names (package names + build flags) are exactly the same. |

| 2025-07-29 00:11:16 +0200 | <dolio> | In the cabal case the mechanism is more like hash consing, I guess. Every time you build something you remember what options it and all its dependencies were built with, and store the result indexed by all that information. Then if that ever shows up again in a build plan, you use what you already built. |

| 2025-07-29 00:00:52 +0200 | <dolio> | Of <exp> that is. |
| 2025-07-29 00:00:43 +0200 | <dolio> | If you write something like `case <exp> of <pattern> -> ... case <exp> of ...`, then I think it will do that CSE. |

| 2025-07-28 23:58:35 +0200 | <dolio> | GHC does some limited cases of it, though. |
| 2025-07-28 23:58:18 +0200 | <dolio> | Also, it's not always an optimization. |
| 2025-07-28 23:57:53 +0200 | <dolio> | It's an optimization you might try on code. Usually you wouldn't say you're going to guarantee there are no common subexpressions, just factor them out if you notice them. |
| 2025-07-28 23:56:15 +0200 | <jreicher> | dolio: I didn't know anyone was trying to do something like CSE (haven't heard the term before). Sounds dangerously close to testing for graph isomorphism. |
