|
||||
* This is one fun bit of code ...
|
||||
* Some easy listening music is suggested while trying to understand this
|
||||
* code e.g. Iron Maiden
|
||||
*
|
||||
* For anyone attempting to understand it :
|
||||
*
|
||||
* The core code is implemented here with simple stubs for memcpy().
|
||||
*
|
||||
* All local labels are prefixed with Lmemcpy_
|
||||
* Following the prefix a label starting f is used in the forward copy code
|
||||
* while a label using b is used in the backwards copy code
|
||||
* The source and destination addresses determine whether a forward or
|
||||
* backward copy is performed.
|
||||
* Separate bits of code are used to deal with the following situations
|
||||
* for both the forward and backwards copy.
|
||||
* unaligned source address
|
||||
* unaligned destination address
|
||||
* Separate copy routines are used to produce an optimised result for each
|
||||
* of these cases.
|
||||
* The copy code will use LDM/STM instructions to copy up to 32 bytes at
|
||||
* a time where possible.
|
||||
*
|
||||
* Note: r12 (aka ip) can be trashed during the function along with
|
||||
* r0-r3 although r0-r2 have defined uses i.e. src, dest, len through out.
|
||||
* Additional registers are preserved prior to use i.e. r4, r5 & lr
|
||||
*
|
||||
* Apologies for the state of the comments ;-)

|

* There are many well known branch-free sequences which are used
|
||||
* for determining whether a zero-byte is contained within a word.
|
||||
* These sequences are generally much more efficent than loading
|
||||
* and comparing each byte individually.
|
||||
*
|
||||
* The expression [1,2]:
|
||||
*
|
||||
* (1) ~(((x & 0x7f7f7f7f) + 0x7f7f7f7f) | (x | 0x7f7f7f7f))
|
||||
*
|
||||
* evaluates to a non-zero value if any of the bytes in the
|
||||
* original word is zero.
|
||||
*
|
||||
* It also has the useful property that bytes in the result word
|
||||
* that correspond to non-zero bytes in the original word have
|
||||
* the value 0x00, while bytes corresponding to zero bytes have
|
||||
* the value 0x80. This allows calculation of the first (and
|
||||
* last) occurrence of a zero byte within the word (useful for C's
|
||||
* str* primitives) by counting the number of leading (or
|
||||
* trailing) zeros and dividing the result by 8. On machines
|
||||
* without (or with slow) clz() / ctz() instructions, testing
|
||||
* each byte in the result word for zero is necessary.
|
||||
*
|
||||
* This typically takes 4 instructions (5 on machines without
|
||||
* "not-or") not including those needed to load the constant.
|
||||
*
|
||||
*
|
||||
* The expression:
|
||||
*
|
||||
* (2) ((x - 0x01010101) & ~x & 0x80808080)
|
||||
*
|
||||
* evaluates to a non-zero value if any of the bytes in the
|
||||
* original word is zero.
|
||||
*
|
||||
* On little endian machines, the first byte in the result word
|
||||
* that corresponds to a zero byte in the original byte is 0x80,
|
||||
* so clz() can be used as above. On big endian machines, and
|
||||
* little endian machines without (or with a slow) clz() insn,
|
||||
* testing each byte in the original for zero is necessary.
|
||||
*
|
||||
* This typically takes 3 instructions (4 on machines without
|
||||
* "and with complement") not including those needed to load
|
||||
* constants.
|
||||
*
|
||||
*
|
||||
* The expression:
|
||||
*
|
||||
* (3) ((x - 0x01010101) & 0x80808080)
|
||||
*
|
||||
* always evaluates to a non-zero value if any of the bytes in
|
||||
* the original word is zero. However, in rare cases, it also
|
||||
* evaluates to a non-zero value when none of the bytes in the
|
||||
* original word is zero.
|
||||
*
|
||||
* To account for possible false positives, each byte of the
|
||||
* original word must be checked when the expression evaluates to
|
||||
* a non-zero value. However, because it is simpler than those
|
||||
* presented above, code that uses it will be faster as long as
|
||||
* the rate of false positives is low.
|
||||
*
|
||||
* This is likely, because the the false positive can only occur
|
||||
* if the most siginificant bit of a byte within the word is set.
|
||||
* The expression will never fail for typical 7-bit ASCII strings.
|
||||
*
|
||||
* This typically takes 2 instructions not including those needed
|
||||
* to load constants.

| first, we divide the divisor and dividend by two until

1: cmpil #0x10000, %d0
|
||||
bcs 2f
|

lsrl #1, %d0
|
||||
lsrl #1, %d1
|
||||
bra 1b
|
||||
2:
|
||||
|
||||
| now we can do the divide. to avoid overflow, we have to
|
||||
| do the divide in two parts, high and low, and add the
|
||||
| results together:
|
||||
movew %d1, %d2 | save low(dividend)
|
||||
clrw %d1
|
||||
swap %d1 | %d1 = dividend >> 16
|
||||
divuw %d0, %d1 | do the high divide
|
||||
moveal %d1, %a1 | save high divide result
|
||||
movew %d2, %d1 | concat(remainder, low(dividend))
|
||||
divuw %d0, %d1 | do the low divide
|
||||
movel %a1, %d0 | recover high divide result
|
||||
swap %d0
|
||||
clrw %d0 | %d0 = finished high divide result
|
||||
andil #0xffff, %d1 | %d1 = finished low divide result
|
||||
addl %d1, %d0 | %d0 = quotient guess
|
||||
|
||||
| the quotient we have so far is only a guess. the divide we
|
||||
| did above was really the divide of some dividendB by some
|
||||
| divisorB, where the following hold:
|
||||
|
|
||||
| (dividend - divisor) <= dividendB <= dividend
|
||||
| (divisor / 2) < divisorB <= divisor
|
||||
|
|
||||
| so our guess quotient cannot be less than our real desired
|
||||
| quotient. however, it might be one too big.
|
||||
|
|
||||
| to adjust this quotient, we multiply it by the original
|
||||
| divisor and subtract the result from the original dividend.
|
||||
| if the result is nonnegative, our guessed quotient was
|
||||
| correct, and the subtraction result is our remainder.
|
||||
| if the result is negative, our guessed quotient was one
|
||||
| too big, and the subtraction result plus the original
|
||||
| divisor is our remainder.
|
||||
|
|
||||
| as in mulsi3, we have to do the multiply in stages to avoid
|
||||
| overflow:
|
||||
|
||||
movel %sp@(12), %d2 | load divisor
|
||||
swap %d2
|
||||
movel %d0, %d1
|
||||
muluw %d2, %d1 | high(divisor) * low(guess)
|
||||
moveal %d1, %a1 | save high(divisor) * low(guess)
|
||||
swap %d2
|
||||
movel %d0, %d1
|
||||
swap %d1
|
||||
muluw %d2, %d1 | low(divisor) * high(guess)
|
||||
addl %a1, %d1
|
||||
swap %d1
|
||||
clrw %d1 | %d1 = finished high multiply result
|
||||
moveal %d2, %a1 | save original divisor
|
||||
muluw %d0, %d2 | low(guess) * low(divisor)
|

addl %d1, %d2 | %d2 = guess * divisor
