Sorry if it is FAQ.
I want to enable SSE4.2 and saw an article that I must pass target-cpu=native.
I looked at Page Moved but could not find the way.
Could you tell me it or a place of information?
Thanks.

Cargo docs lack the necessary explanations.
I think there are two ways to do what you want, but so far I have found only the first:
cargo rustc --release --bin my_prog_name -- -C target-cpu=native
Thank you!
It seems to work (could compile), but I could not get SSE instructions...
Does anyone know that how to let u64's count method use SSE instruction?
On ARM, to get a nice 2x speedup using NEON instructions in this code snippet, it was necessary to pass:
-C target-feature=+neon
