Created attachment 447648 [details] [diff] [review] Patch demonstrating that JSOP_XMLOBJECT is never used. SpiderMonkey supports, but never generates, the JSOP_XMLOBJECT bytecode. By inspection of the code, there doesn't seem to be anything that generates JSOP_XMLOBJECT, and the attached patch, which adds 'JS_ASSERT(0)' calls to each point in the code that processes JSOP_XMLOBJECT bytecodes, causes no regressions. The bytecode should be deleted.
See the comment atop jsopcode.tbl for how to "remove" an op -- thanks for catching this one. /be

Comment on attachment 450252 [details] [diff] [review] Delete the JSOP_XMLOBJECT bytecode. You also need to bump the bytecode version (see jsxdrapi.h, search for c0d3 I think), in case someone had ancient serialized code that used the opcode; r=me with that as well.
