;;- 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
|

;;- Immediate integer operand constraints:
|
||
;;- 'I' 1 .. 8
|
||
;;- 'J' -32768 .. 32767
|
||
;;- 'K' all integers EXCEPT -128 .. 127
|
||
;;- 'L' -8 .. -1

|

|
||
|
||
;;- 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.
