Similar or duplicate checks are scattered around the code before doing the dictionary load. Also the entire branch in GenerateCallNormal that handles global/builtin receiver is guaranteed to bail out from GenerateDictionaryLoad, so there is no point in generating it at all. The purpose of the patch is: - making C++ code more compact and transparent, - not generating dead code. There is a tiny performance gain. The patch is ia32 only for now. Please tell me if I am missing anything. Review URL: http://codereview.chromium.org/2801007 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@4926 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
