Aurelien's patch series is about TCG, and a"target" there is the host where code is emulated. So, I'd expect it to be worth trying: if it brings 7% performance improvement to MIPS, it should also bring a measurable performance improvement to SPARC as well. -- Regards, Artyom Tarasenko SPARC and PPC PReP under qemu blog: http://tyom.blogspot.com/search/label/qemu
