This was the minimal amount of predicates I could easily cache without
introducing extra cached stages. The predicates that are not cached
here, like `CppType::getTypeSize` and `getCanonicalLanguageType`, appear
to be cheap.
I've tested that this avoids recomputation of the IR type system by
running
grep -c 'Starting to evaluate predicate CppType::CppType::getIRType_dispred'
on the evaluator log for `IRSanity.ql`. It drops from 4 to 1. The
pretty-printed DIL drops from 79,175 lines to 76,326 lines.
Semmle QL
This open source repository contains the standard QL libraries and queries that power LGTM, and the other products that Semmle makes available to its customers worldwide.
How do I learn QL and run queries?
There is extensive documentation on getting started with writing QL. You can use the interactive query console on LGTM.com or the QL for Eclipse plugin to try out your queries on any open-source project that's currently being analyzed.
Contributing
We welcome contributions to our standard library and standard checks. Do you have an idea for a new check, or how to improve an existing query? Then please go ahead and open a pull request! Before you do, though, please take the time to read our contributing guidelines. You can also consult our style guides to learn how to format your QL for consistency and clarity, how to write query metadata, and how to write query help documentation for your query.
