I've been checking out spidermonkey's bytecode for an academic research. I got the bytecodes list from this file: http://mxr.mozilla.org/mozilla-central/source/js/src/jsopcode.tbl#106.
When I started to check out websites, and go over their bytecodes, I noticed that there are a at least three opcodes that are not in the tbl file: 236, 240, 235 (that's what I found this far).
Doesn't anyone know what they mean, or when can I find a more complete tbl file ???
Thanks! :-)
Your SpiderMonkey version doesn't match the code you are looking at. mozilla-central currently corresponds to Firefox 9. Your SpiderMonkey version most likely corresponds to the current release version however (Firefox 6). If you look at the file in the mozilla-release repository you will see the "additional" opcodes: http://hg.mozilla.org/releases/mozilla-release/file/FIREFOX_6_0_RELEASE/js/src/jsopcode.tbl#l604
