  • In other reporting it did seem he was proactive in contacting the parliamentary authorities once he received advice on the donations. The spouse situation is tricky because his wife isn’t an elected official or even a political operative. However I doubt the donations would have been made of she doesn’t sometimes appear with her husband on official occasions.

    Also the pearl clutching by the Tories is hypocrisy of the highest order given some of the stuff their members got away with.

    Still it’s not a good look and hopefully the party officials are making sure other ministers are up-to-date on all declarations. You don’t want this to be the start of a string of stories.



  • QEMU is always going to focus on emulation fidelity first and there are few shortcuts. With floating point the differences aren’t generally in the numbers but in how the NaNs and other edge cases are handled. If you want to execute FP heavy code you should be cross compiling anyway.




  • Pretty much. From v8.0 onwards all the extra features are indicated by id flags. Stuff that is relevant to kernel mode will generally be automatically handled by the kernel patching itself on booting up and in user space some libraries will select appropriately accelerated functions when the ISA extensions are probed. There are a bunch off advisory instructions encoded in the hint space that will be effectively NOPs on older hardware but will enhance execution if run on newer hardware.

    If you want to play with newer instructions have a look at QEMUs “max” CPU.
