+;;- divide instructions. The TARGET_5200 flag turns the use of the

+;;- instruction definitions
+
+;;- @@The original PO technology requires these to be ordered by speed,

+
+;;- 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 registers can be used
+;;- 'r' either a data or an address register can be used.
+;;- 'x' if one of the Sun FPA registers
+;;- 'y' if one of the Low Sun FPA registers (fpa0-fpa15).
+
+;;- 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).

+;;- 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 <ea>,Dr:Dq;
+;;- divu.l <ea>,Dr:Dq; muls.l <ea>,Dr:Dq; mulu.l <ea>,Dr:Dq; and
+;;- fscale. The TARGET_68060 flag turns the use of the opcodes off.
+
+;;- FPA port explanation:
+
+;;- Usage of the Sun FPA and the 68881 together
+
+;;- The current port of gcc to the sun fpa disallows use of the m68881
+;;- instructions completely if code is targeted for the fpa. This is
+;;- for the following reasons:
+
+;;- 1) Expressing the preference hierarchy (ie. use the fpa if you
+;;- can, the 68881 otherwise, and data registers only if you are
+;;- forced to it) is a bitch with the current constraint scheme,
+;;- especially since it would have to work for any combination of
+;;- -mfpa, -m68881.
+
+;;- 2) There are no instructions to move between the two types of
+;;- registers; the stack must be used as an intermediary.
+
+;;- It could indeed be done; I think the best way would be to have
+;;- separate patterns for TARGET_FPA (which implies a 68881),
+;;- TARGET_68881, and no floating point co-processor. Use
+;;- define_expands for all of the named instruction patterns, and
+;;- include code in the FPA instruction to deal with the 68881 with
+;;- preferences specifically set to favor the fpa. Some of this has
+;;- already been done:
+;;-
+;;- 1) Separation of most of the patterns out into a TARGET_FPA
+;;- case and a TARGET_68881 case (the exceptions are the patterns
+;;- which would need one define_expand and three define_insn's under
+;;- it (with a lot of duplicate code between them) to replace the
+;;- current single define_insn. These are mov{[ds]f,[ds]i} and the
+;;- first two patterns in the md.
+;;-
+;;- Some would still have to be done:
+;;-
+;;- 1) Add code to the fpa patterns which correspond to 68881
+;;- patterns to deal with the 68881 case (including preferences!).
+;;- What you might actually do here is combine the fpa and 68881 code
+;;- back together into one pattern for those instructions where it's
+;;- absolutely necessary and save yourself some duplicate code. I'm
+;;- not completely sure as to whether you could get away with doing
+;;- this only for the mov* insns, or if you'd have to do it for all
+;;- named insns.
+;;- 2) Add code to the mov{[ds]f,[ds]i} instructions to handle
+;;- moving between fpa regs and 68881 regs.
+
+;;- Since the fpa is more powerful than the 68881 and also has more
+;;- registers, and since I think the resultant md would be medium ugly
+;;- (lot's of duplicate code, ugly constraint strings), I elected not
+;;- to do this change.
+
+;;- Another reason why someone *might* want to do the change is to
+;;- control which register classes are accessed in a slightly cleaner
+;;- way than I have. See the blurb on CONDITIONAL_REGISTER_USAGE in
+;;- the internals manual.
+
+;;- Yet another reason why someone might want to do this change is to
+;;- allow use of some of the 68881 insns which have no equivalent on
+;;- the fpa. The sqrt instruction comes fairly quickly to mind.
+
+;;- If this is ever done, don't forget to change sun3.h so that
+;;- it *will* define __HAVE_68881__ when the FPA is in use.
+
+;;- Condition code hack
+
+;;- When a floating point compare is done in the fpa, the resulting
+;;- condition codes are left in the fpastatus register. The values in
+;;- this register must be moved into the 68000 cc register before any
+;;- jump is executed. Once this has been done, regular jump
+;;- instructions are fine (ie. floating point jumps are not necessary.
+;;- They are only done if the cc is in the 68881).
+
+;;- The instructions that move the fpastatus register to the 68000
+;;- register clobber a data register (the move cannot be done direct).
+;;- These instructions might be bundled either with the compare
+;;- instruction, or the branch instruction. If we were using both the
+;;- fpa and the 68881 together, we would wish to only mark the
+;;- register clobbered if we were doing the compare in the fpa, but I
+;;- think that that decision (whether to clobber the register or not)
+;;- must be done before register allocation (makes sense) and hence we
+;;- can't know if the floating point compare will be done in the fpa
+;;- or the fp. So whenever we are asked for code that uses the fpa,
+;;- we will mark a data register as clobbered. This is reasonable, as
+;;- almost all floating point compare operations done with fpa code
+;;- enabled will be done in the fpa. It's even more reasonable since
+;;- we decided to make the 68881 and the fpa mutually exclusive.
+
+;;- We place to code to move the fpastatus register inside of a
+;;- define_expand so that we can do it conditionally based on whether
+;;- we are targeting an fpa or not.
+
+;;- This still leaves us with the question of where we wish to put the
+;;- code to move the fpastatus reg. If we put it in the compare
+;;- instruction, we can restrict the clobbering of the register to
+;;- floating point compares, but we can't take advantage of floating
+;;- point subtracts & etc. that alter the fpastatus register. If we
+;;- put it in the branch instruction, all branches compiled with fpa
+;;- code enabled will clobber a data register, but we will be able to
+;;- take advantage of fpa subtracts. This balance favors putting the
+;;- code in with the compare instruction.
+
+;;- Note that if some enterprising hacker should decide to switch
+;;- this, he'll need to modify the code in NOTICE_UPDATE_CC.
+
+;;- Usage of the top 16 fpa registers
+
+;;- The only locations which we may transfer fpa registers 16-31 from
+;;- or to are the fpa registers 0-15. (68000 registers and memory
+;;- locations are impossible). This causes problems in gcc, which
+;;- assumes that mov?? instructions require no additional registers
+;;- (see section 11.7) and since floating point moves *must* be
+;;- supported into general registers (see section 12.3 under
+;;- HARD_REGNO_OK_FOR_MODE_P) from anywhere.
+
+;;- My solution was to reserve fpa0 for moves into or out of these top
+;;- 16 registers and to disparage the choice to reload into or out of
+;;- these registers as much as I could. That alternative is always
+;;- last in the list, so it will not be used unless all else fails. I
+;;- will note that according to my current information, sun's compiler
+;;- doesn't use these top 16 registers at all.
+
+;;- There is another possible way to do it. I *believe* that if you
+;;- make absolutely sure that the code will not be executed in the
+;;- reload pass, you can support the mov?? names with define_expands
+;;- which require new registers. This may be possible by the
+;;- appropriate juggling of constraints. I may come back to this later.
+
+;;- Usage of constant RAM
+
+;;- This has been handled correctly (I believe) but the way I've done
+;;- it could use a little explanation. The constant RAM can only be
+;;- accessed when the instruction is in "command register" mode.
+;;- "command register" mode means that no accessing of memory or the
+;;- 68000 registers is being done. This can be expressed easily in
+;;- constraints, so generally the mode of the instruction is
+;;- determined by a branch off of which_alternative. In outputting
+;;- instructions, a 'w' means to output an access to the constant ram
+;;- (if the arg is CONST_DOUBLE and is one of the available
+;;- constants), and 'x' means to output a register pair (if the arg is
+;;- a 68000 register) and a 'y' is the combination of the above two
+;;- processes. You use a 'y' in two operand DF instructions where you
+;;- *know* the other operand is an fpa register, you use an 'x' in DF
+;;- instructions where the arg might be a 68000 register and the
+;;- instruction is *not* in "command register" mode, and you use a 'w'
+;;- in two situations: 1) The instruction *is* in command register
+;;- mode (and hence won't be accessing 68000 registers), or 2) The
+;;- instruction is a two operand SF instruction where you know the
+;;- other operand is an fpa register.
+
+;;- Optimization issues
+
+;;- I actually think that I've included all of the fpa instructions
+;;- that should be included. Note that if someone is interested in
+;;- doing serious floating point work on the sun fpa, I would advise
+;;- the use of the "asm" instruction in gcc to allow you to use the
+;;- sin, cos, and exponential functions on the fpa board.
+
+;;- END FPA Explanation Section.
+
+
+;;- 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

+;; 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. This is done in
