From bab6aec1255ba2ec8de3ae0363958e2ff26ce25d Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 8 Nov 2019 09:03:23 +0100 Subject: [PATCH] x86: introduce operand type "class" Many operand types, in particular the various kinds of registers, can't be combined with one another (neither in templates nor in register entries), and hence it is not a good use of resources (memory as well as execution time) to represent them as individual bits of a bit field. --- gas/ChangeLog | 14 ++++ gas/config/tc-i386.c | 100 +++++++++++++++----------- opcodes/ChangeLog | 18 +++++ opcodes/i386-gen.c | 55 ++++++++++---- opcodes/i386-init.h | 4 ++ opcodes/i386-opc.h | 17 +++-- opcodes/i386-opc.tbl | 10 +-- opcodes/i386-reg.tbl | 166 +++++++++++++++++++++---------------------- 8 files changed, 238 insertions(+), 146 deletions(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index 6376ce114f..a2937f8663 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,17 @@ +2019-11-08 Jan Beulich + + * config/tc-i386.c (operand_type_set, operand_type_and, + operand_type_and_not, operand_type_or, operand_type_xor): Handle + "class" field specially. + (anyimm): New. + (operand_type_check, operand_size_match, + operand_type_register_match, pi, md_assemble, is_short_form, + process_suffix, check_byte_reg, check_long_reg, check_qword_reg, + check_word_reg, process_operands, build_modrm_byte): Use "class" + instead of "reg" field. + (optimize_imm): Likewise.
