 * Test coverage
27
 *
28
 * At present the tests are only reasonably comprehensive for lf.add.s and
29
 * lf.div.s. This is intended as a template for future work, and still has
30
 * omissions even so.
31
 *
32
 * Basic tests are provided for all single precision floating point
33
 * numbers. Since Or1ksim translates these operations into host FP, there is
34
 * little point in testing more of the subtleties of IEEE 745.
35
 *
36
 * However in future this test could be used with OpenRISC hardware, in which
37
 * case exhaustive testing would be essential.

 * Coding conventions
46
 *
47
 * A simple rising stack is provided to starting at _stack and pointed to by
48
 * r1. r1 points to the next free word. Only 32-bit registers may be pushed
49
 * onto the stack.
50
 *
51
 * Temporary labels up to 49 are reserved for macros and subroutines. Each is
52
 * used only once in any macro or subroutine. You can get in a serious mess if
53
 * you get local label clashing in macros.
54
 *
55
 * Arguments to functions are passed in r3 through r8.
56
 * r9 is the link (return address)
57
 * r11 is for returning results
58
 * r2 through r11 are not preserved across calls. All other registers are.

 * For the record, the single precision format has 1 sign bit, 8 exponent bits
78
 * and 23 fraction bits.
79
 *
80
 *   seeeeeeeefffffffffffffffffffffff
81
 *
82
 * The exponent is biased by 2^7 - 1 (i.e 127 is subtracted from the value to
83
 * give the actual exponent). Normalized numbers have a non-zero exponent (up
84
 * to 2^8 - 2) and an implicit 1 before the fraction. Thus the value
85
 * represented is
86
 *
87
 *   (-1)^s * 1.fffffffffffffffffffffff * 2^(eeeeeeee - (2^7 - 1))
88
 *
89
 * Special values used are:
90
 *
91
 *  Zeroes                Exponent is zero,    fraction also zero
92
 *  Denormalized numbers  Exponent is zero,    fraction non-zero
93
 *  Infinities            Exponent is 2^8 - 1, fraction is zero
94
 *  NaNs                  Exponent is 2^8 - 1, fraction is non-zero
95
 *
96
 * The top bit of the fraction in a NaN is often used to indicate the type of
97
 * NaN. If 1, it is a "quiet" NaN, if 0 it is a "signalling" NaN. Quiet NaN's
98
 * are generally propagated for FP errors. Signalling NaN's can be used for
99
 * more unusual purposes
100
 *
101
 * In general any other bits of the NaN fraction are just propagated unchanged.
