+-- x86 Template String Description
+-- ===============================
+--
+-- Each template string is a list of [match:]pattern pairs,
+-- separated by "|". The first match wins. No match means a
+-- bad or unsupported combination of operand modes or sizes.
+--
+-- The match part and the ":" is omitted if the operation has
+-- no operands. Otherwise the first N characters are matched
+-- against the mode strings of each of the N operands.
+--
+-- The mode string for each operand type is (see parseoperand()):
+-- Integer register: "rm", +"R" for eax, ax, al, +"C" for cl
+-- FP register: "f", +"F" for st0
+-- Index operand: "xm", +"O" for [disp] (pure offset)
+-- Immediate: "i", +"S" for signed 8 bit, +"1" for 1,
+-- +"I" for arg, +"P" for pointer
+-- Any: +"J" for valid jump targets
+--
+-- So a match character "m" (mixed) matches both an integer register
+-- and an index operand (to be encoded with the ModRM/SIB scheme).
+-- But "r" matches only a register and "x" only an index operand
+-- (e.g. for FP memory access operations).
+--
+-- The operand size match string starts right after the mode match
+-- characters and ends before the ":". "dwb" or "qdwb" is assumed, if empty.
+-- The effective data size of the operation is matched against this list.
+--
+-- If only the regular "b", "w", "d", "q", "t" operand sizes are
+-- present, then all operands must be the same size. Unspecified sizes
+-- are ignored, but at least one operand must have a size or the pattern
+-- won't match (use the "byte", "word", "dword", "qword", "tword"
+-- operand size overrides. E.g.: mov dword [eax], 1).
+--
+-- If the list has a "1" or "2" prefix, the operand size is taken
+-- from the respective operand and any other operand sizes are ignored.
+-- If the list contains only ".", all operand sizes are ignored.
+-- If the list has a "/" prefix, the concatenated (mixed) operand sizes
+-- are compared to the match.
+--
+-- E.g. "rrdw" matches for either two dword registers or two word
+-- registers. "Fx2dq" matches an st0 operand plus an index operand
+-- pointing to a dword (float) or qword (double).
+--
+-- Every character after the ":" is part of the pattern string:
+-- Hex chars are accumulated to form the opcode (left to right).
+-- "n" disables the standard opcode mods
+-- (otherwise: -1 for "b", o16 prefix for "w", rex.w for "q")
+-- "X" Force REX.W.
+-- "r"/"R" adds the reg. number from the 1st/2nd operand to the opcode.
+-- "m"/"M" generates ModRM/SIB from the 1st/2nd operand.
+-- The spare 3 bits are either filled with the last hex digit or
+-- the result from a previous "r"/"R". The opcode is restored.
+-- "u" Use VEX encoding, vvvv unused.
+-- "v"/"V" Use VEX encoding, vvvv from 1st/2nd operand (the operand is
+-- removed from the list used by future characters).
+-- "L" Force VEX.L
+--
+-- All of the following characters force a flush of the opcode:
+-- "o"/"O" stores a pure 32 bit disp (offset) from the 1st/2nd operand.
+-- "s" stores a 4 bit immediate from the last register operand,
+-- followed by 4 zero bits.
+-- "S" stores a signed 8 bit immediate from the last operand.
+-- "U" stores an unsigned 8 bit immediate from the last operand.
+-- "W" stores an unsigned 16 bit immediate from the last operand.
+-- "i" stores an operand sized immediate from the last operand.
+-- "I" dito, but generates an action code to optionally modify
+-- the opcode (+2) for a signed 8 bit immediate.
+-- "J" generates one of the REL action codes from the last operand.
