830-- x86 Template String Description
831-- ===============================
832--
833-- Each template string is a list of [match:]pattern pairs,
834-- separated by "|". The first match wins. No match means a
835-- bad or unsupported combination of operand modes or sizes.
836--
837-- The match part and the ":" is omitted if the operation has
838-- no operands. Otherwise the first N characters are matched
839-- against the mode strings of each of the N operands.
840--
841-- The mode string for each operand type is (see parseoperand()):
842-- Integer register: "rm", +"R" for eax, ax, al, +"C" for cl
843-- FP register: "f", +"F" for st0
844-- Index operand: "xm", +"O" for [disp] (pure offset)
845-- Immediate: "i", +"S" for signed 8 bit, +"1" for 1,
846-- +"I" for arg, +"P" for pointer
847-- Any: +"J" for valid jump targets
848--
849-- So a match character "m" (mixed) matches both an integer register
850-- and an index operand (to be encoded with the ModRM/SIB scheme).
851-- But "r" matches only a register and "x" only an index operand
852-- (e.g. for FP memory access operations).
853--
854-- The operand size match string starts right after the mode match
855-- characters and ends before the ":". "dwb" or "qdwb" is assumed, if empty.
856-- The effective data size of the operation is matched against this list.
857--
858-- If only the regular "b", "w", "d", "q", "t" operand sizes are
859-- present, then all operands must be the same size. Unspecified sizes
860-- are ignored, but at least one operand must have a size or the pattern
861-- won't match (use the "byte", "word", "dword", "qword", "tword"
862-- operand size overrides. E.g.: mov dword [eax], 1).
863--
864-- If the list has a "1" or "2" prefix, the operand size is taken
865-- from the respective operand and any other operand sizes are ignored.
866-- If the list contains only ".", all operand sizes are ignored.
867-- If the list has a "/" prefix, the concatenated (mixed) operand sizes
868-- are compared to the match.
869--
870-- E.g. "rrdw" matches for either two dword registers or two word
871-- registers. "Fx2dq" matches an st0 operand plus an index operand
872-- pointing to a dword (float) or qword (double).
873--
874-- Every character after the ":" is part of the pattern string:
875-- Hex chars are accumulated to form the opcode (left to right).
876-- "n" disables the standard opcode mods
877-- (otherwise: -1 for "b", o16 prefix for "w", rex.w for "q")
878-- "X" Force REX.W.
879-- "r"/"R" adds the reg. number from the 1st/2nd operand to the opcode.
880-- "m"/"M" generates ModRM/SIB from the 1st/2nd operand.
881-- The spare 3 bits are either filled with the last hex digit or
882-- the result from a previous "r"/"R". The opcode is restored.
883--
884-- All of the following characters force a flush of the opcode:
885-- "o"/"O" stores a pure 32 bit disp (offset) from the 1st/2nd operand.
886-- "S" stores a signed 8 bit immediate from the last operand.
887-- "U" stores an unsigned 8 bit immediate from the last operand.
888-- "W" stores an unsigned 16 bit immediate from the last operand.
889-- "i" stores an operand sized immediate from the last operand.
890-- "I" dito, but generates an action code to optionally modify
891-- the opcode (+2) for a signed 8 bit immediate.
892-- "J" generates one of the REL action codes from the last operand.
