When determining whether a referenced type should be emitted, various tests are done: - has the type been emitted already? hash table lookup - does the translation unit match? string comparison - is this the last translation unit? read bool variable The translation unit tests were added in recent commits and followed the hash table lookups. This resulted in a performance regression affecting Android continuous integration tests. The lookups require a hash calculation and an equality check if the hash is present. The equality checks are expensive deep equalities rather than pointer comparisons. This change reorders the tests so that the lookups happen last. This speeds up abidw by more than a factor of 10 for one Android library. * src/abg-writer.cc (write_translation_unit): Reorder referenced type emission tests for efficiency.

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, fonctions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to compare two ABI Corpora (apparently the plural of corpus is copora, heh, that's cool), provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
