From: Matthew Malcomson Date: Thu, 9 May 2019 09:29:22 +0000 (+0100) Subject: [binutils][aarch64] New SVE_SHRIMM_UNPRED_22 operand. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3c17238bc9fe8a078a6199470291f07bab9c64c8;p=binutils-gdb.git [binutils][aarch64] New SVE_SHRIMM_UNPRED_22 operand. Include a new iclass to extract the variant from the most significant 3 bits of this operand. Instructions such as rshrnb include a constant shift amount as an operand, where the most significant three bits of this operand determine what size elements the instruction is operating on. The new SVE_SHRIMM_UNPRED_22 operand denotes this constant encoded in bits 22:20-19:18-16 while the new sve_shift_tsz_hsd iclass denotes that the SVE qualifier is encoded in bits 22:20-19. gas/ChangeLog: 2019-05-09 Matthew Malcomson * config/tc-aarch64.c (parse_operands): Handle new SVE_SHRIMM_UNPRED_22 operand. include/ChangeLog: 2019-05-09 Matthew Malcomson * opcode/aarch64.h (enum aarch64_opnd): New SVE_SHRIMM_UNPRED_22 operand.
