Summary: In some cases the shift/extend needs to be explicitly parsed together with the register, rather than as a separate operand. This is needed for addressing modes where the instruction as a whole dictates the scaling/extend, rather than specific bits in the instruction. By parsing them as a single operand, we avoid the need to pass an extra operand in all CodeGen patterns (because all operands need to have an associated value), and we avoid the need to update TableGen to accept operands that have no associated bits in the instruction. An added benefit of parsing them together is that the assembler can give a sensible diagnostic if the scaling is not correct. This is patch [2/4] in a series to add assembler/disassembler support for SVE's contiguous LD1 (scalar+scalar) instructions: - Patch [1/4]: https://reviews.llvm.org/D45687 - Patch [2/4]: https://reviews.llvm.org/D45688 - Patch [3/4]: https://reviews.llvm.org/D45689 - Patch [4/4]: https://reviews.llvm.org/D45690 Reviewers: fhahn, rengolin, javed.absar, huntergr, SjoerdMeijer, t.p.northover, echristo, evandro Reviewed By: fhahn, SjoerdMeijer Subscribers: kristof.beyls, llvm-commits Differential Revision: https://reviews.llvm.org/D45688 llvm-svn: 330394 |
