unresolved import crate::arch::x86_64::__m64

[jerryc05]

Just a short note, packed_simd has a known break on Windows 10. Please see this issue: rust-lang/packed_simd#308

The workaround is not so simple. We might have to modify the version of encoding_rs dependency to encoding_rs = { git = "https://github.com/hsivonen/encoding_rs" } in both these files:

• crates/searcher/Cargo.toml
• encoding_rs_io src in cargo cache

The error log of RUSTFLAGS="-C target-cpu=native" cargo build --release --features 'simd-accel' is:

[BurntSushi]

This isn't really in ripgrep's power to fix. @hsivonen has to publish a new release of encoding_rs with this PR, which was merged a bit ago.

[jerryc05]

Yeah I understand. I am just posting this here for reference BTW.

[hsivonen]

I've published encoding_rs 0.8.25 with the PR mentioned above.

I noticed that even before the semver break to 1.0, cfg-if did an MSRV increase without a semver break (when updating to edition 2018), so there's no point in holding back encoding_rs changes out of MSRV increase concern.

[BurntSushi]

Thanks! And yeah, I thought you stopped tracking MSRV stuff a while back. I did the same for ripgrep. (But still do it for some libraries.)
