[llvm-dev] Fwd: Superoptimization for RISC-V: What is the state of the art now?

[Wei Wu (吴伟) via llvm-dev]

Hi all,

I appreciate it if you can drop some information/papers/open source project
urls that are related to superoptimization. Although I am targeting RISC-V
ISA, there might be some other research works / open source projects
available in the LLVM community.

(Sorry for the duplicate email.)

Hi all,

In the last code optimization meeting (formly code-size-reduction and
code-speed-opt), the idea of using superoptimization[4] for RISC-V had been
discussed. I'm interested in this area. After a quick search I found very
few results, though. GNU/Embecosm had a superopt [1] but I am not sure it
still works either for GCC 10 or RISC-V backend. Google open sourced a
LLVM-IR level tool named souper[2] would help. STOKE[3] is yet another
optimizer which targets x86 only.

I appreciate it if you can drop some information/papers/open source project
urls that are related to superoptimization. I am going to stand on the
basis of gnu-superopt[1], and not sure it is the right/effective way to go.

Thanks.
