Subject: [RFC PATCH 3/3] disas: Remove old libopcode i386 disassembler
Date: Tue, 12 Apr 2022 18:58:36 +0200 [thread overview]
Message-ID: <20220412165836.355850-4-thuth@redhat.com> (raw)
In-Reply-To: <20220412165836.355850-1-thuth@redhat.com>
Capstone should be superior to the old libopcode disassembler,
so we can drop the old file nowadays.

-/* The SystemV/386 SVR3.2 assembler, and probably all AT&T derived
- ix86 Unix assemblers, generate floating point instructions with
- reversed source and destination registers in certain cases.
- Unfortunately, gcc and possibly many other programs use this
- reversed syntax, so we're stuck with it.
-
- eg. `fsub %st(3),%st' results in st = st - st(3) as expected, but
- `fsub %st,%st(3)' results in st(3) = st - st(3), rather than
- the expected st(3) = st(3) - st
-
- This happens with all the non-commutative arithmetic floating point
- operations with two register operands, where the source register is
- %st, and destination register is %st(i).
-
- The affected opcode map is dceX, dcfX, deeX, defX. */

- 'C' => print 's' or 'l' ('w' or 'd' in Intel mode) depending on operand
- . size prefix
- 'D' => print 'w' if no register operands or 'w', 'l' or 'q', if
- . suffix_always is true
- 'E' => print 'e' if 32-bit form of jcxz
- 'F' => print 'w' or 'l' depending on address size prefix (loop insns)
- 'G' => print 'w' or 'l' depending on operand size prefix (i/o insns)
- 'H' => print ",pt" or ",pn" branch hint
- 'I' => honor following macro letter even in Intel mode (implemented only
- . for some of the macro letters)
- 'J' => print 'l'
- 'K' => print 'd' or 'q' if rex prefix is present.
- 'L' => print 'l' if suffix_always is true
- 'N' => print 'n' if instruction has no wait "prefix"
- 'O' => print 'd' or 'o' (or 'q' in Intel mode)
- 'P' => print 'w', 'l' or 'q' if instruction has an operand size prefix,
- . or suffix_always is true. print 'q' if rex prefix is present.
- 'Q' => print 'w', 'l' or 'q' if no register operands or suffix_always
- . is true
- 'R' => print 'w', 'l' or 'q' ('d' for 'l' and 'e' in Intel mode)
- 'S' => print 'w', 'l' or 'q' if suffix_always is true
- 'T' => print 'q' in 64bit mode and behave as 'P' otherwise
- 'U' => print 'q' in 64bit mode and behave as 'Q' otherwise
- 'V' => print 'q' in 64bit mode and behave as 'S' otherwise
- 'W' => print 'b', 'w' or 'l' ('d' in Intel mode)
- 'X' => print 's', 'd' depending on data16 prefix (for XMM)
- 'Y' => 'q' if instruction has an REX 64bit overwrite prefix
- 'Z' => print 'q' in 64bit mode and behave as 'L' otherwise
-
- Many of the above letters print nothing in Intel mode. See "putop"
- for the details.
-
- Braces '{' and '}', and vertical bars '|', indicate alternative
- mnemonic strings for AT&T, Intel, X86_64 AT&T, and X86_64 Intel
- modes. In cases where there are only two alternatives, the X86_64
- instruction is reserved, and "(bad)" is printed.
