 *	Interface
 *		Almost the same as original. Please see the comments in "fpu.h".
 *
 *
 *	Why assembly?
 *		The reason is not really speed, but to get infinities,
 *		NANs and flags finally working.
 *
 *
 *	How to maintain Mac and x86 FPU flags -- plan B
 *
 *	regs.piar is not updated.
 *
 *	regs.FPU fpcr always contains the real 68881/68040 control word.
 *
 *	regs.FPU fpsr is not kept up-to-date, for efficiency reasons.
 *	Most of the FPU commands update this in a way or another, but it is not
 *	read nearly that often. Therefore, three host-specific words hold the
 *	status byte and exception byte ("x86_status_word"), accrued exception
 *	byte ("x86_status_word_accrued") and the quotient byte ("FPU fpsr.quotient"),
 *	as explained below.
 *
 *	CONDITION CODE - QUOTIENT - EXCEPTION STATUS - ACCRUED EXCEPTION
 *		CONDITION CODE (N,Z,I,NAN)
 *		-	updated after each opcode, if needed.
 *		-	x86 assembly opcodes call FXAM and store the status word to
 *			"x86_status_word".
 *		-	When regs.FPU fpsr is actually used, the value of "x86_status_word"
 *			is translated.
 *		QUOTIENT BYTE
 *		-	Updated by frem, fmod, frestore(null frame)
 *		-	Stored in "FPU fpsr.quotient" in correct bit position, combined when
 *			regs.FPU fpsr is actually used.
 *		EXCEPTION STATUS (BSUN,SNAN,OPERR,OVFL,UNFL,DZ,INEX2,INEX1)
 *		-	updated after each opcode, if needed.
 *		-	Saved in x86 form in "x86_status_word".
 *		-	When regs.FPU fpsr is actually used, the value of "x86_status_word"
 *			is translated.
 *		-	Only fcc_op can set BSUN
 *		ACCRUED EXCEPTION (ACCR_IOP,ACCR_OVFL,ACCR_UNFL,ACCR_DZ,ACCR_INEX)
 *		-	updated after each opcode, if needed.
 *		-	Logically OR'ed in x86 form to "x86_status_word_accrued".
 *		-	When regs.FPU fpsr is actually used, the value of
 *			"x86_status_word_accrued" is translated.
 *		
 *		When "x86_status_word" and "x86_status_word_accrued" are stored,
 *		all pending x86 FPU exceptions are cleared, if there are any.
 *
 *		Writing to "regs.FPU fpsr" reverse-maps to x86 status/exception values and
 *		stores the values in "x86_status_word", "x86_status_word_accrued"
 *		and "FPU fpsr.quotient".
 *
 *		So, "x86_status_word" and "x86_status_word_accrued" are not in
 *		correct bit positions and have x86 values, but "FPU fpsr.quotient" is at
 *		correct position.
 *
 *		Note that it does not matter that the reverse-mapping is not exact
 *		(both SW_IE and SW_DE are mapped to ACCR_IOP, but ACCR_IOP maps to
 *		SW_IE only), the MacOS always sees the correct exception bits.
 *
 *		Also note the usage of the fake BSUN flag SW_FAKE_BSUN. If you change
 *		the x86 FPU code, you must make sure that you don't generate any FPU
 *		stack faults.

 *
 *  TODO:
 *    - Exceptions are not implemented.
 *    - All tbyte variables should be aligned to 16-byte boundaries.
 *		  (for best efficiency).
 *		- FTRAPcc code looks like broken.
 *		- If USE_3_BIT_QUOTIENT is 0, exceptions should be checked after
 *			float -> int rounding (frem,fmod).
 *		- The speed can be greatly improved. Do this only after you are sure
 *			that there are no major bugs.
 *		- Support for big-endian byte order (but all assembly code needs to
 *			be rewritten anyway)
 *			I have some non-portable code like *((uae_u16 *)&m68k_dreg(regs, reg)) = newv;
 *			Sorry about that, you need to change these. I could do it myself, but better
 *			not, I would have no way to test them out.
 *			I tried to mark all spots with a comment TODO_BIGENDIAN.
 *		- to_double() may need renormalization code. Or then again, maybe not.
 *		- Signaling NANs should be handled better. The current mapping of
 *			signaling nan exception to denormalized operand exception is only
 *			based on the idea that the (possible) handler sees that "something
 *			seriously wrong" and takes the same action. Should not really get (m)any
 *			of those since normalization is handled on to_exten()

If USE_3_BIT_QUOTIENT is set to 1, FREM and FMOD use a faster version
with only 3 quotient bits (those provided by the x86 FPU). If set to 0,
they calculate the same 7 bits that m68k does. It seems (as for now) that
3 bits suffice for all Mac programs I have tried.

If you decide that you need all 7 bits (USE_3_BIT_QUOTIENT is 0),
consider checking the host exception flags after FISTP (search for
"TODO:Quotient". The result may be too large to fit into a dword.
