They are documented in the following links: * luti2: https://developer.arm.com/documentation/ddi0602/2024-03/SVE-Instructions/LUTI2--Lookup-table-read-with-2-bit-indices-?lang=en * luti4: https://developer.arm.com/documentation/ddi0602/2024-03/SVE-Instructions/LUTI4--Lookup-table-read-with-4-bit-indices-?lang=en These instructions use new SVE2 vector operands. They are called SVE_Zm1_23_INDEX, SVE_Zm2_22_INDEX, and Zm3_12_INDEX and they have 1 bit, 2 bit, and 3 bit indices respectively. For these new operands, we defined a new inserter and a new extractor. The lsb and width of these new operands are the same as many existing operands but the convention is to give different names to fields that serve different purpose so we introduced new fields in aarch64-opc.c and aarch64-opc.h. We made a design choice for the second operand of the halfword variant of luti4 with two register tables. We could have either defined a new operand, like SVE_Znx2, or we could have use the existing operand SVE_ZnxN. With the new operand, we would need to implement constraints on register lists based on either operand or opcode flag. With existing operand, we could just existing constraint checks using opcode flag. We chose the second approach and went with SVE_ZnxN and added opcode flag to enforce lengths of vector register list operands. This way, we can reuse the existing constraint check logic. --- Hi, Regression tested for aarch64-none-elf and found no regressions. Ok for binutils-master? I don't have commit access so can someone please commit on my behalf?
