Yes — migrated the in-place tolower loop in `QPACK::_encode_header` to `ts::memcpy_tolower` in faeb167c8. The helper's contract now explicitly supports `dst == src`: every SIMD body loads a full block into a register before storing back at the same offset, and the AVX-512BW masked tail does masked-load/masked-store at the same offset. Partial overlap (where `dst != src` but the ranges intersect) is still unsupported. Unit test coverage for the in-place form added too. `UrlRewrite.cc` and `HPACK.cc` have similar byte-at-a-time loops with separate buffers — those are easy follow-up migrations if you'd like them rolled in, or I can leave them as a separate PR. -- This is an automated message from the Apache Git Service.
