There's a bunch of reasons, but mainly: * new functionality (both internal and new language additions); * and the increasing use of CodeStubAssembler <https://v8project.blogspot.de/2017/11/csa.html> to write shipped code (vs. implementing builtins as self-hosted JS, shipping the source files and compiling at runtime). > Our current aim is to reduce the size of binary. I suppose this is the binary in decompressed form, and not something like an APK? It'd theoretically be possible to support loading from compressed snapshot blobs (for roughly 1MB savings), but this is not implemented currently. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
