2 * fpu_x86.cpp - 68881/68040 fpu code for x86/Windows an Linux/x86.
3 *
4 * Basilisk II (C) 1997-2001 Christian Bauer
5 *
6 * MC68881/68040 fpu emulation
7 *
8 * Based on UAE FPU, original copyright 1996 Herman ten Brugge,
9 * rewritten for x86 by Lauri Pesonen 1999-2000,
10 * accomodated to GCC's Extended Asm syntax by Gwenole Beauchesne 2000.

25 *
26 *
27 * Interface
28 * Almost the same as original. Please see the comments in "fpu.h".
29 * Call fpu_init() and fpu_set_integral_fpu() before cpu thread starts up.
30 *
31 *
32 * Why assembly?
33 * The reason is not really speed, but to get infinities,
34 * NANs and flags finally working.
35 *
36 *
37 * How to maintain Mac and x86 FPU flags -- plan B
38 *
39 * regs.piar is not updated.
40 *
41 * regs.fpcr always contains the real 68881/68040 control word.
42 *
43 * regs.fpsr is not kept up-to-date, for efficiency reasons.
44 * Most of the FPU commands update this in a way or another,
45 * but it is not read nearly that often. Therefore, three host-specific
46 * words hold the status byte and exception byte ("sw"), accrued exception
47 * byte ("sw_accrued") and the quotient byte ("sw_quotient"), as explained below.
48 *
49 * CONDITION CODE - QUOTIENT - EXCEPTION STATUS - ACCRUED EXCEPTION
50 * CONDITION CODE (N,Z,I,NAN)
51 * updated after each opcode, if needed.
52 * x86 assembly opcodes call FXAM and store the status word to "sw".
53 * When regs.fpsr is actually used, the value of "sw" is translated.
54 * QUOTIENT BYTE
55 * Updated by frem, fmod, frestore(null frame)
56 * Stored in "sw_quotient" in correct bit position, combined when
57 * regs.fpsr is actually used.
58 * EXCEPTION STATUS (BSUN,SNAN,OPERR,OVFL,UNFL,DZ,INEX2,INEX1)
59 * updated after each opcode, if needed.
60 * Saved in x86 form in "sw".
61 * When regs.fpsr is actually used, the value of "sw" is translated.
62 * Only fcc_op can set BSUN
63 * ACCRUED EXCEPTION (ACCR_IOP,ACCR_OVFL,ACCR_UNFL,ACCR_DZ,ACCR_INEX)
64 * updated after each opcode, if needed.
65 * Logically OR'ed in x86 form to "sw_accrued".
66 * When regs.fpsr is actually used, the value of "sw_accrued" is translated.
67 *
68 * When "sw" and "sw_accrued" are stored, all pending x86 FPU
69 * exceptions are cleared, if there are any.
70 *
71 * Writing to "regs.fpsr" reverse-maps to x86 status/exception values
72 * and stores the values in "sw", "sw_accrued" and "sw_quotient".
73 *
74 * So, "sw" and "sw_accrued" are not in correct bit positions
75 * and have x86 values, but "sw_quotient" is at correct position.
76 *
77 * Note that it does not matter that the reverse-mapping is not exact
78 * (both SW_IE and SW_DE are mapped to ACCR_IOP, but ACCR_IOP maps to SW_IE
79 * only), the MacOS always sees the correct exception bits.
80 *
81 * Also note the usage of the fake BSUN flag SW_FAKE_BSUN. If you change the
82 * x86 FPU code, you must make sure that you don't generate any FPU stack faults.
83 *
84 *
85 * x86 co-processor initialization:
86 *
87 * Bit Code Use
88 * 0 IM Invalid operation exception mask 1 Disabled
89 * 1 DM Denormalized operand exception mask 1 Disabled
90 * 2 ZM Zerodivide exception mask 1 Disabled
91 * 3 OM Overflow exception mask 1 Disabled
92 * 4 UM Underflow exception mask 1 Disabled
93 * 5 PM Precision exception mask 1 Disabled
94 * 6 - - - -
95 * 7 IEM Interrupt enable mask 0 Enabled
96 * 8 PC Precision control\ 1 - 64 bits
97 * 9 PC Precision control/ 1 /
98 * 10 RC Rounding control\ 0 - Nearest even
99 * 11 RC Rounding control/ 0 /
100 * 12 IC Infinity control 1 Affine
101 * 13 - - - -
102 * 14 - - - -
103 * 15 - - - -
104 *
105 *
106 * TODO:
107 * - Exceptions are not implemented.
108 * - All tbyte variables should be aligned to 16-byte boundaries.
109 * (for best efficiency).
110 * - FTRAPcc code looks like broken.
111 * - If USE_3_BIT_QUOTIENT is 0, exceptions should be checked after
112 * float -> int rounding (frem,fmod).
113 * - The speed can be greatly improved. Do this only after you are sure
114 * that there are no major bugs.
115 * - Support for big-endian byte order (but all assembly code needs to
116 * be rewritten anyway)
117 * I have some non-portable code like *((uae_u16 *)&m68k_dreg(regs, reg)) = newv;
118 * Sorry about that, you need to change these. I could do it myself, but better
119 * not, I would have no way to test them out.
120 * I tried to mark all spots with a comment TODO_BIGENDIAN.
121 * - to_double() may need renormalization code. Or then again, maybe not.
122 * - Signaling NANs should be handled better. The current mapping of
123 * signaling nan exception to denormalized operand exception is only
124 * based on the idea that the (possible) handler sees that "something
125 * seriously wrong" and takes the same action. Should not really get (m)any
126 * of those since normalization is handled on to_exten()

152 If USE_3_BIT_QUOTIENT is set to 1, FREM and FMOD use a faster version
153 with only 3 quotient bits (those provided by the x86 FPU). If set to 0,
154 they calculate the same 7 bits that m68k does. It seems (as for now) that
155 3 bits suffice for all Mac programs I have tried.
156
157 If you decide that you need all 7 bits (USE_3_BIT_QUOTIENT is 0),
158 consider checking the host exception flags after FISTP (search for
159 "TODO:Quotient". The result may be too large to fit into a dword.
