;;- 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

;;- 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 ;;- TARGET_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. By changing TARGET_DEFAULT to include TARGET_68040_ONLY, ;;- you can make these instructions the default.
;;- 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 ,Dr:Dq; ;;- divu.l ,Dr:Dq; muls.l ,Dr:Dq; mulu.l ,Dr:Dq; and ;;- fscale. The TARGET_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.

;; For PIC calls, in order to be able to support ;; dynamic linker LAZY BINDING, all the procedure calls need to go ;; through the PLT (Procedure Linkage Table) section in PIC mode. ;; ;; PIC calls are handled by loading the address of the function into a ;; register (via movsi), then emitting a register indirect call using ;; the “jsr” function call syntax. ;; ;; When outputting MIT syntax (e.g. on Suns), we add a bogus extra ;; operand to the jbsr statement to indicate that this call should ;; go through the PLT (why? because this is the way that Sun does it). ;; ;; We have different patterns for PIC calls and non-PIC calls. The ;; different patterns are only used to choose the right syntax. ;; ;; The svr4 m68k assembler recognizes this syntax: bsr FUNC@PLTPC' and it ;; will create the correct relocation entry (R_68K_PLT32) for FUNC', ;; that tells the linker editor to create an entry for FUNC' in PLT ;; section at link time. However, all global objects reference are still ;; done by using OBJ@GOT'. So, the goal here is to output the function ;; call operand as FUNC@PLTPC', but output object operand as OBJ@GOT'. ;; We need to have a way to differentiate these two different operands. ;; ;; The strategy I use here is to use SYMBOL_REF_FLAG to differentiate ;; these two different operands. The macro LEGITIMATE_PIC_OPERAND_P needs ;; to be changed to recognize function calls symbol_ref operand as a valid ;; PIC operand (by checking whether SYMBOL_REF_FLAG is set). This will ;; avoid the compiler to load this symbol_ref operand into a register. ;; Remember, the operand “foo@PLTPC” cannot be called via jsr directly ;; since the value is a PC relative offset, not a real address. ;; ;; All global objects are treated in the similar way as in SUN3. The only ;; difference is: on m68k svr4, the reference of such global object needs ;; to end with a suffix “@GOT” so the assembler and linker know to create ;; an entry for it in GOT (Global Offset Table) section.
