From 0f3e1d2708a0fcc43f4e3c3d1cea92358eb1fc56 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Fri, 19 Jul 2024 11:42:16 +0100 Subject: [PATCH] MIPS/opcodes: Correct documentation for R6 operand types The "-t", "-u", "-v", and "-w" operand types refer 'rt' operand, which is the target register rather than the source register. Additionally the "-x" and "-y" R6 operand types refer 'rs' rather than 'rt' operand of the BOVC/BNVC and the BEQC/BNEC instructions respectively. Also the "-x" operand type does not permit 'rs' to be the same as 'rt'. Correct inline documentation in opcode/mips.h accordingly. --- include/opcode/mips.h | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) diff --git a/include/opcode/mips.h b/include/opcode/mips.h index 3ef74eb623a..b4a8c4a7852 100644 --- a/include/opcode/mips.h +++ b/include/opcode/mips.h @@ -984,13 +984,12 @@ mips_opcode_32bit_p (const struct mips_opcode *mo) "-b" (-131072 .. 131071) << 3 at bit 0 "-d" Same as destination register GP "-s" 5 bit source register specifier (OP_*_RS) not $0 - "-t" 5 bit source register specifier (OP_*_RT) not $0 - "-u" 5 bit source register specifier (OP_*_RT) greater than OP_*_RS - "-v" 5 bit source register specifier (OP_*_RT) not $0 not OP_*_RS - "-w" 5 bit source register specifier (OP_*_RT) less than or equal to OP_*_RS - "-x" 5 bit source register specifier (OP_*_RT) greater than or - equal to OP_*_RS - "-y" 5 bit source register specifier (OP_*_RT) not $0 less than OP_*_RS + "-t" 5 bit target register specifier (OP_*_RT) not $0 + "-u" 5 bit target register specifier (OP_*_RT) greater than OP_*_RS + "-v" 5 bit target register specifier (OP_*_RT) not $0 not OP_*_RS + "-w" 5 bit target register specifier (OP_*_RT) less than or equal to OP_*_RS + "-x" 5 bit source register specifier (OP_*_RS) greater than OP_*_RT + "-y" 5 bit source register specifier (OP_*_RS) not $0 less than OP_*_RT "-A" symbolic offset (-262144 .. 262143) << 2 at bit 0 "-B" symbolic offset (-131072 .. 131071) << 3 at bit 0
