;;- Information about MCF5200 port.

;;- The MCF5200 "ColdFire" architecture is a reduced version of the
;;- 68k ISA.  Differences include reduced support for byte and word
;;- operands and the removal of BCD, bitfield, rotate, and integer
;;- divide instructions.  The TARGET_COLDFIRE flag turns the use of the
;;- removed opcodes and addressing modes off.
;;- 


;;- instruction definitions

;;- @@The original PO technology requires these to be ordered by speed,
;;- @@    so that assigner will pick the fastest.

;;- See file "rtl.def" for documentation on define_insn, match_*, et. al.

;;- When naming insn's (operand 0 of define_insn) be careful about using
;;- names from other targets machine descriptions.

;;- cpp macro #define NOTICE_UPDATE_CC in file tm.h handles condition code
;;- updates for most instructions.

;;- Operand classes for the register allocator:
;;- 'a' one of the address registers can be used.
;;- 'd' one of the data registers can be used.
;;- 'f' one of the m68881/fpu registers can be used
;;- 'r' either a data or an address register can be used.

;;- Immediate Floating point operator constraints
;;- 'G' a floating point constant that is *NOT* one of the standard
;;   68881 constant values (to force calling output_move_const_double
;;   to get it from rom if it is a 68881 constant).
;;
;;   See the functions standard_XXX_constant_p in output-m68k.c for more
;; info.

;;- Immediate integer operand constraints:
;;- 'I'  1 .. 8
;;- 'J'  -32768 .. 32767
;;- 'K'  all integers EXCEPT -128 .. 127
;;- 'L'  -8 .. -1
;;- 'M'  all integers EXCEPT -256 .. 255
;;- 'N'  24 .. 31
;;- 'O'  16
;;- 'P'  8 .. 15

;;- Assembler specs:
;;- "%."    size separator ("." or "")			move%.l d0,d1
;;- "%-"    push operand "sp@-"				move%.l d0,%-
;;- "%+"    pop operand "sp@+"				move%.l d0,%+
;;- "%@"    top of stack "sp@"				move%.l d0,%@
;;- "%!"    fpcr register
;;- "%$"    single-precision fp specifier ("s" or "")	f%$add.x fp0,fp1
;;- "%&"    double-precision fp specifier ("d" or "")	f%&add.x fp0,fp1

;;- Information about 68040 port.

;;- The 68040 executes all 68030 and 68881/2 instructions, but some must
;;- be emulated in software by the OS.  It is faster to avoid these
;;- instructions and issue a library call rather than trapping into
;;- the kernel.  The affected instructions are fintrz and fscale.  The
;;- TUNE_68040 flag turns the use of the opcodes off.

;;- The '040 also implements a set of new floating-point instructions
;;- which specify the rounding precision in the opcode.  This finally
;;- permit the 68k series to be truly IEEE compliant, and solves all
;;- issues of excess precision accumulating in the extended registers.
;;- By default, GCC does not use these instructions, since such code will
;;- not run on an '030.  To use these instructions, use the -m68040-only
;;- switch.

;;- These new instructions aren't directly in the md.  They are brought
;;- into play by defining "%$" and "%&" to expand to "s" and "d" rather
;;- than "".

;;- Information about 68060 port.

;;- The 68060 executes all 68030 and 68881/2 instructions, but some must
;;- be emulated in software by the OS.  It is faster to avoid these
;;- instructions and issue a library call rather than trapping into
;;- the kernel.  The affected instructions are: divs.l <ea>,Dr:Dq;
;;- divu.l <ea>,Dr:Dq; muls.l <ea>,Dr:Dq; mulu.l <ea>,Dr:Dq; and
;;- fscale.  The TUNE_68060 flag turns the use of the opcodes off.

;;- Some of these insn's are composites of several m68000 op codes.
;;- The assembler (or final @@??) insures that the appropriate one is
;;- selected.
