Like always using SSE2, since they have their own registers, instead of going to the stack of the 387 unit? Ain't that smarter? About VESA: one can never have too many compiler optimizations :D Faster is always good in emulation, and if you can have gains by just switching compilers, why not use this? I promise I'll look into the VESA code some time. I'm in love with QEMU, you know ;D On Wed, 04 Aug 2004 23:25:01 +0200, Fabrice Bellard wrote: > FP is not used in QEMU except for the CPU emulation itself, so expect no > gain.
