* WIP: initial RVV implementation Co-authored-by: gong-flying <gongxiaofei24@iscas.ac.cn> * Fix issue with SIMDJSON_CONDITIONAL_INCLUDE in rvv/implementation.h Co-authored-by: gong-flying <gongxiaofei24@iscas.ac.cn> * drop RISC-V V-extension auto-detection in cmake - Remove CMake logic that adds -DSIMDJSON_IS_RVV=1. - Let SIMDJSON_IS_RVV be determined by portability.h. - Translate placeholder comment to English. Co-authored-by: gong-flying <gongxiaofei24@iscas.ac.cn> * fixing amalgamation. Co-authored-by: gong-flying <gongxiaofei24@iscas.ac.cn> * adding base Co-authored-by: gong-flying <gongxiaofei24@iscas.ac.cn> --------- Co-authored-by: gong-flying <gongxiaofei24@iscas.ac.cn> Co-authored-by: Daniel Lemire <daniel@lemire.me>
