- Subject: [PATCH 08/16] [binutils][aarch64] New sve_size_bh iclass.
- References: <1556721866-21052-1-git-send-email-matthew.malcomson@arm.com>
Add new iclass sve_size_bh to handle instructions that have two variants
encoded with the SVE_sz field.
This iclass behaves the same as the sve_size_sd iclass, but it has a
nicer name for those instructions that choose between variants using the
"B" and "H" size qualifiers.
include/ChangeLog:
2019-04-04 Matthew Malcomson <matthew.malcomson@arm.com>
* opcode/aarch64.h (enum aarch64_insn_class): Add sve_size_bh iclass.
opcodes/ChangeLog:
2019-04-04 Matthew Malcomson <matthew.malcomson@arm.com>
* aarch64-asm.c (aarch64_encode_variant_using_iclass): Handle
sve_size_bh iclass encode.
* aarch64-dis.c (aarch64_decode_variant_using_iclass): Handle
sve_size_bh iclass decode.
