Yes, the restoreVolatile could restore |input| (or just its type or payload register). The "masm.popValue(input)" immediately before that is a bit confusing, but I think that's just to discard the stack space we used for the call argument. |input| should be exactly the same Value we pushed on the stack before the call, so restoreVolatile can safely clobber it with the original values. Hope this helps, Jan _______________________________________________ dev-tech-js-engine-internals mailing list dev-tech-js-engine-internals@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-js-engine-internals
