Wouldn't an unprivileged EFLAGS-lookalike cause problems of the CLI-HLT persuasion? And "process signal registers", while sounding attractive, aren't really a feasible alternative, given that the number of processes running even on uniprocessors are overwhelming, at least. Plus, if they're beyond CPU control, privilege issues arise again. In short, yes, there are many alternatives, but the current model works, and not just for x86. And you know what engineers say.. |
