Tonton Aaron a posté quelques news sur son site :
Looks like the CPU fan on my main computer died, so until my replacement arrives, I’m stuck doing low-speed work using a borrowed fan from a lesser computer. As a result, I’ve decided to plunge headfirst into the MIPS recompiler rewrite. So far I have about 1/4 of the instructions rewritten, as well as the core control flow analysis. I still need to finish up the instructions, write the final register allocator, and then get it working, so I think it will be a few weeks before I have anything to show for it. I’m currently guessing it will be about 2x as efficient as the old one. I’m also restructuring it a bit so that it will be possible to add an x86-64 backend eventually. The more I do this, the more I realize just how much of a pain in the ass it is to emulate a 64-bit chip on a 32-bit chip. I could be way more efficient on the x86-64 when doing 64-bit math and logic, not to mention that having an extra 8 registers will be quite helpful as well. But the x86-64 stuff is definitely not going to happen until I have some actual hardware, so don’t expect it too soon.
