- ;;- 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 "".
-
-
- ;;- 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.

- ;; 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.
- ;;
- ;; It is important to note that the "jsr" syntax is always used for
- ;; PIC calls, even on machines in which GCC normally uses the "jbsr"
- ;; syntax for non-PIC calls. This keeps at least 1 assembler (Sun)
- ;; from emitting incorrect code for a PIC call.
- ;;
- ;; We have different patterns for PIC calls and non-PIC calls. The
- ;; different patterns are only used to choose the right syntax
- ;; ("jsr" vs "jbsr").
- ;;
- ;; On svr4 m68k, PIC stuff is done differently. 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. 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 legal
- ;; 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
