[Qemu-devel] [PATCH 0/3] target/riscv: use tcg_lookup_and_goto_ptr

Posted by Emilio G. Cota 7 years, 2 months ago

There are a few more places where the lookup could be inserted,
but I think these are the ones that will matter performance-wise.

Perf results in patch 3's log.

Regarding the benchmarks: I'd have used SPEC06 but I don't have
much time to get it to compile. Is there a guide on how to do so?
Ideally I'd like to use the fedora image, which works very well.

Thanks,

		Emilio
