|entryCount| tracks -- in fast-to-check manner -- the number of entries in the hashtable. But to actually enumerate entries, we have to loop through all of |table|, checking for entries that are actually live. A live entry is indicated by a zero |hash| in the entry. The |memset| would properly zero that; removing the memset will not.
It's not entirely clear whether a memset that overwrites a lot of stuff but is maybe simpler, is faster than compiler-generated likely-SIMD code that zeroes out *just* |hash| fields in all the entries. But I am going to guess that SIMD is good enough. For now, we should just do the simple and thing: don't distinguish POD and non-POD, and know that the compiler is going to recognize that |mem.addr()->~T()| is a no-op when T is trivial. So with POD, the loop should degenerate to just zeroing |hash| at consistent offset, and SIMD will eat that up, and it can't be *that* different from the memset in performance (if it is at all).
This repository holds the code for a unified application platform for XUL-based
applications. It is a hard fork from the Mozilla code repository (mozilla-central)
with an ESR-52 fork point.
In addition to further development based on the Mozilla upstream code, and
selective cherry-picking of directly-applicable patches, this repository has its
own development and holds the base for a future platform to be used by XUL
applications.
This repository will contain at least one application to demonstrate and make use
of the platform: The Basilisk web browser, a close twin to Mozilla's Firefox.
