This patch introduces an LSX-optimized version of `analyze_source_file` for the `loongarch64` target. Similar to existing SSE2 implementation for x86, this version: - Processes 16-byte chunks at a time using LSX vector intrinsics. - Quickly identifies newlines in ASCII-only chunks. - Falls back to the generic implementation when multi-byte UTF-8 characters are detected or in the tail portion.

Is this now testable on CI? |
Yes. |
|
How? |
I may have misunderstood you earlier. What I meant is that after this PR (#146636), the patch passed testing on our private native build CI. |
|
Ok so I guess this target isn't, and cannot, be tested on the rust project CI? In that case, @bors r+ rollup |
