;;- The MCF5200 "ColdFire" architecture is a reduced version of the
25
;;- 68k ISA.  Differences include reduced support for byte and word
26
;;- operands and the removal of BCD, bitfield, rotate, and integer
27
;;- divide instructions.  The TARGET_COLDFIRE flag turns the use of the

79
 
80
;;- The 68040 executes all 68030 and 68881/2 instructions, but some must

82
;;- instructions and issue a library call rather than trapping into
83
;;- the kernel.  The affected instructions are fintrz and fscale.  The
84
;;- TUNE_68040 flag turns the use of the opcodes off.
85
 
86
;;- The '040 also implements a set of new floating-point instructions
87
;;- which specify the rounding precision in the opcode.  This finally
88
;;- permit the 68k series to be truly IEEE compliant, and solves all
89
;;- issues of excess precision accumulating in the extended registers.
90
;;- By default, GCC does not use these instructions, since such code will
91
;;- not run on an '030.  To use these instructions, use the -m68040-only
92
;;- switch.
93
 
94
;;- These new instructions aren't directly in the md.  They are brought
95
;;- into play by defining "%$" and "%&" to expand to "s" and "d" rather
96
;;- than "".

;;- Information about 68060 port.
99
 
100
;;- The 68060 executes all 68030 and 68881/2 instructions, but some must
101
;;- be emulated in software by the OS.  It is faster to avoid these

;;- instructions and issue a library call rather than trapping into
103
;;- the kernel.  The affected instructions are: divs.l ,Dr:Dq;
104
;;- divu.l ,Dr:Dq; muls.l ,Dr:Dq; mulu.l ,Dr:Dq; and
105
;;- fscale.  The TUNE_68060 flag turns the use of the opcodes off.
106
 
107
;;- Some of these insn's are composites of several m68000 op codes.
