[PATCH 1/1] AArch64: Add LUTI ACLE for SVE2

2024-07-10 Thread vladimir.miloserdov
This patch introduces support for LUTI2/LUTI4 ACLE for SVE2. LUTI instructions are used for efficient table lookups with 2-bit or 4-bit indices. LUTI2 reads indexed 8-bit or 16-bit elements from the low 128 bits of the table vector using packed 2-bit indices, while LUTI4 can read from the low 128
