- procedure memccpy (optimized assembler version for the 80960K series)
-
- dest_addr = memccpy (dest_addr, src_addr, char, len)
-
- copy len bytes pointed to by src_addr to the space pointed to by
- dest_addr, stopping if char is copied. If char is copied,
- return address of byte after char in dest string; else null.
-
-
- Undefined behavior will occur if the end of the source array is in
- the last two words of the program's allocated memory space. This
- is so because the routine fetches ahead. Disallowing the fetch
- ahead would impose a severe performance penalty.
-
- Undefined behavior will also occur if the source and destination
- strings overlap.
-
- Strategy:
-
- Fetch the source array by words and store them by words to the
- destination array, until there are fewer than three bytes left
- to copy. Then, using the last word of the source (the one that
- contains the remaining 0, 1, 2, or 3 bytes to be copied), store
- a byte at a time until Ldone.
-
- Tactics:
-
- 1) Do NOT try to fetch and store the words in a word aligned manner
- because, in my judgement, the performance degradation experienced due
- to non-aligned accesses does NOT outweigh the time and complexity added
- by the preamble and convoluted body that would be necessary to assure
- alignment. This is supported by the intuition that most source and
- destination arrays (even more true of most big source arrays) will
- be word aligned to begin with.
-
- 2) Rather than decrementing len to zero,
- I calculate the address of the byte after the last byte of the
- destination array, and quit when the destination byte pointer passes
- that.

- procedure memccpy (optimized assembler version for the 80960CA)
-
- dest_addr = memccpy (dest_addr, src_addr, char, len)
-
- copy len bytes pointed to by src_addr to the space pointed to by
- dest_addr, stopping if char is copied. If char is copied,
- return address of byte after char in dest string; else null.
-
- Undefined behavior will occur if the end of the source array is in
- the last two words of the program's allocated memory space. This
- is so because the routine fetches ahead. Disallowing the fetch
- ahead would impose a severe performance penalty.
-
- Undefined behavior will also occur if the source and destination
- strings overlap.
-
-
- This program handles five cases:
-
- 1) both arguments start on a word boundary
- 2) neither are word aligned, but they are offset by the same amount
- 3) source is word aligned, destination is not
- 4) destination is word aligned, source is not
- 5) neither is word aligned, and they are offset by differing amounts
-
- At the time of this writing, only g0 thru g7 and g13 are available
- for use in this leafproc; other registers would have to be saved and
- restored. These nine registers, plus tricky use of g14 are sufficient
- to implement the routine.

- src_addr = memchr (src_addr, char, max_bytes)
-
- searching from src_addr for a span of max_bytes bytes, return a

-
- Undefined behavior will occur if the last byte of the source array
- is in the last two words of the program's allocated memory space.
- This is so because memchr fetches ahead. Disallowing the fetch
- ahead would impose a severe performance penalty.
-
- Strategy:
-
- Fetch the source array by words and scanbyte the words for the
- char until either a word with the byte is found or max_bytes is
- exhausted. In the former case, move through the word to find the
- matching byte and return its memory address. In the latter case,
- return zero (null).
-
- Tactics:
-
- 1) Do NOT try to fetch the words in a word aligned manner because,
- in my judgement, the performance degradation experienced due to
- non-aligned accesses does NOT outweigh the time and complexity added
- by the preamble that would be necessary to assure alignment. This
- is supported by the intuition that most source arrays (even more
- true of most big source arrays) will be word aligned to begin with.
-
- 2) Rather than decrementing max_bytes to zero, I calculate the
- address of the byte after the last byte of the source array, and
- quit when the source byte pointer passes that. Refining, actually
- I calculate the address of the fifth byte after the last byte of
- the source array, because the source byte pointer is ahead of the
- actual examination point due to fetch ahead.

- lexicographically greater. Do not compare more than max_bytes bytes.
-
- Undefined behavior will occur if the end of either source array
- is in the last two words of the program's allocated memory space.
- This is so because memcmp fetches ahead. Disallowing the fetch ahead
- would impose a severe performance penalty.
-
- Strategy:
-
- Fetch the source strings by words and compare the words until either
- a differing word is found or max_bytes is exhausted. In the former
- case, move through the words to find the differing byte and return
- plus or minus one, appropriately. In the latter case, return zero
- (equality).
-
- Tactics:
-
- 1) Do NOT try to fetch the words in a word aligned manner because,
- in my judgement, the performance degradation experienced due to
- non-aligned accesses does NOT outweigh the time and complexity added
- by the preamble that would be necessary to assure alignment. This
- is supported by the intuition that most source arrays (even more
- true of most big source arrays) will be word aligned to begin with.
-
- 2) Rather than decrementing max_bytes to zero, I calculate the
- address of the byte after the last byte of the source_1 array, and
- quit when the source byte pointer passes that.

- These routines will work even if the arrays overlap. The standard

- a byte at a time until Ldone.

- Tactics:

- that.
-
- 3) For overlapping arrays where the source starts at a lower address
- than the destination the move is performed in reverse order.
-
- 4) Overlapping arrays where the source starts at a higher address
- are treated like non-overlapping case. Where the two arrays exactly
- coincide, the routine is short-circuited; no move is Ldone at all.
- This costs only one cycle.

- Tactics:
-
- 1) Do NOT try to fetch the words in a word aligned manner because,
- in my judgement, the performance degradation experienced due to
- non-aligned accesses does NOT outweigh the time and complexity added
- by the preamble that would be necessary to assure alignment. This
- is supported by the intuition that most source arrays (even more

-
- copy the null terminated string pointed to by src_addr to

-
- This routine will fail if the source and destination string
- overlap (in particular, if the end of the source is overlapped
- by the beginning of the destination). The behavior is undefined.
- This is acceptable according to the draft C standard.
-
- Undefined behavior will also occur if the end of the source string
- (i.e. the terminating null byte) is in the last two words of the
- program's allocated memory space. This is so because strcpy fetches
- ahead. Disallowing the fetch ahead would impose a severe performance
- penalty.
-
- Strategy:
-
- Fetch the source string and store the destination string by words
- until the null byte is encountered. When the word with the null
- byte is reached, store it by bytes up through the null byte only.
-
- Tactics:
-
- 1) Do NOT try to fetch and store the words in a word aligned manner
- because, in my judgement, the performance degradation experienced due

-
-
- procedure strcat
-
- dest_addr = strcat (dest_addr, src_addr)
-
- Appends the string pointed to by src_addr to the string pointed
- to by dest_addr. The first character of the source string is
- copied to the location initially occupied by the trailing null
- byte of the destination string. Thereafter, characters are copied
- from the source to the destination up thru the null byte that
- trails the source string.
-
- See the strcpy routine, above, for its caveats, as they apply here too.
-
- Strategy:
-
- Skip to the end (null byte) of the destination string, and then drop
- into the strcpy code.
-
- Tactics:
-
- Skipping to the null byte is Ldone by reading the destination string
- in long-words and scanbyte'ing them, then examining the bytes of the
- word that contains the null byte, until the address of the null byte is
- known. Then we drop into the strcpy routine. It is probable (approx.
- three out of four times) that the destination string as strcpy sees
- it will NOT be word aligned (i.e. that the null byte won't be the
- last byte of a word). But it is not worth the complication to that
- routine to force word aligned memory accesses to be gaurenteed.

- procedure strcpy (optimized assembler version for the CA)
-
- dest_addr = strcpy (dest_addr, src_addr)
-
- copy the null terminated string pointed to by src_addr to
- the string space pointed to by dest_addr. Return the original
- dest_addr.
-
- This routine will fail if the source and destination string
- overlap (in particular, if the end of the source is overlapped
- by the beginning of the destination). The behavior is undefined.
- This is acceptable according to the draft C standard.
-
- Undefined behavior will also occur if the end of the source string
- (i.e. the terminating null byte) is in the last word of the program's
- allocated memory space. This is so because, in several cases, strcpy
- will fetch ahead one word. Disallowing the fetch ahead would impose
- a severe performance penalty.
-
- This program handles five cases:
-
- 1) both arguments start on a word boundary
- 2) neither are word aligned, but they are offset by the same amount
- 3) source is word aligned, destination is not
- 4) destination is word aligned, source is not
- 5) neither is word aligned, and they are offset by differing amounts
-
- At the time of this writing, only g0 thru g7 and g13 are available
- for use in this leafproc; other registers would have to be saved and
- restored. These nine registers, plus tricky use of g14 are sufficient
- to implement the routine. The registers are used as follows:
-
- g0 original dest ptr; not modified, so that it may be returned.
- g1 src ptr; shift count
- g2 dest ptr; 4 bytes of src
- g3 src ptr (word aligned)
- g4 dest ptr (word aligned)
- g5 0xff -- byte extraction mask
- g6 lsw of double word for extraction of 4 bytes (little endian)
- msw of double word for extraction of 4 bytes (big endian)
- g7 msw of double word for extraction of 4 bytes (little endian)
- lsw of double word for extraction of 4 bytes (big endian)
- g13 return address
- g14 byte extracted. When reaches null byte, which is zero, we will
- be in conformance with register conventions, and can return to
- the caller with a clear conscience.
-
- procedure strcat
-
- dest_addr = strcat (dest_addr, src_addr)
-
- Appends the string pointed to by src_addr to the string pointed
- to by dest_addr. The first character of the source string is
- copied to the location initially occupied by the trailing null
- byte of the destination string. Thereafter, characters are copied
- from the source to the destination up thru the null byte that
- trails the source string.

-
- Strategy:
-
- First, skip to the null byte in the destination string. Then

- destination string, until there are fewer than three bytes left
- to copy. Then, using the last word of the source (the one that

-
- If, before exhausting the max_byte count, the null byte is encountered
- in the source string, then just copy up thru the null byte.
-
- Tactics:
-
- 1) Do NOT try to fetch and store the words in a word aligned manner
- because, in my judgement, the performance degradation experienced due

- to implement the routine. The registers are used as follows:
-
- g0 original dest ptr; not modified, so that it may be returned.
- g1 src ptr; shift count
- g2 max_bytes
- g3 src ptr (word aligned)
- g4 dest ptr (word aligned)
- g5 0xff -- byte extraction mask
- Little endian:
- g6 lsw of double word for extraction of 4 bytes
- g7 msw of double word for extraction of 4 bytes
- Big endian:
- g6 msw of double word for extraction of 4 bytes
- g7 lsw of double word for extraction of 4 bytes
- g13 return address
- g14 byte extracted.

- procedure strncmp (optimized assembler version for the CA)
-
- result = strncmp (src1_addr, src2_addr, max_bytes)
-
- compare the null terminated string pointed to by src1_addr to
- the string space pointed to by src2_addr. Return 0 iff the strings
- are equal, -1 if src1_addr is lexicly less than src2_addr, and 1
- if it is lexicly greater. Do not compare more than max_bytes bytes.
-
- Undefined behavior will occur if the end of either source string
- (i.e. the terminating null byte) is in the last word of the program's
- allocated memory space. This is so because, in several cases, strncmp
- will fetch ahead one word. Disallowing the fetch ahead would impose
- a severe performance penalty.
-
- This program handles five cases:
-
- 1) both arguments start on a word boundary
- 2) neither are word aligned, but they are offset by the same amount
- 3) source1 is word aligned, source2 is not
- 4) source2 is word aligned, source1 is not
- 5) neither is word aligned, and they are offset by differing amounts
-
- At the time of this writing, only g0 thru g7 and g14 are available
- for use in this leafproc; other registers would have to be saved and
- restored. These nine registers are sufficient to implement the routine.
- The registers are used as follows:
-
- g0 original src1 ptr; extracted word; return result
- g1 src2 ptr; 0xff -- byte extraction mask
- g2 maximum number of bytes to compare
- g3 src2 word ptr
- Little endian:
- g4 lsw of src1
- g5 msw of src1
- g6 src2 word
- g7 src1 word ptr
- Big endian:
- g4 msw of src1
- g5 lsw of src1
- g6 src1 word ptr
- g7 src2 word
- g13 return address

- procedure strncpy (optimized assembler version for the 80960K Series)
-
- dest_addr = strncpy (dest_addr, src_addr, max_bytes)
-
- copy the null terminated string pointed to by src_addr to the
- string pointed to by dest_addr. Return the original dest_addr.
- If the source string is shorter than max_bytes, then null-pad
- the destination string. If it is longer than max_bytes, the
- copy stops at max_bytes bytes (and no terminating null appears
- in the destination string).
-
- This routine will fail if the source and destination string
- overlap (in particular, if the end of the source is overlapped
- by the beginning of the destination). The behavior is undefined.
- This is acceptable according to the draft C standard.
-
- Undefined behavior will also occur if the end of the source string
- (i.e. the terminating null byte) is in the last two words of the
- program's allocated memory space. This is so because strncpy fetches
- ahead. Disallowing the fetch ahead would impose a severe performance
- penalty.
-
- Strategy:
-
- Fetch and store the strings by words and go to a character move loop
- as soon as a null byte is encountered. If max_bytes is exhausted
- first, then terminate after moving only max_bytes (with the last
- 0, 1, 2, or 3 bytes moved as single bytes, not as a word).
- Otherwise, the character move loop moves the last bytes or the
- source string, and then null-pads the destination string until
- max_bytes is exhausted.
-
- Tactics:
-
- 1) Do NOT try to fetch the words in a word aligned manner because,
- in my judgement, the performance degradation experienced due to
- non-aligned accesses does NOT outweigh the time and complexity added
- by the preamble and convoluted body that would be necessary to assure
- alignment.
-
- 2) When the null byte is encountered in a source word, null out the
- higher-numbered bytes in that word, store the word in the destination,
- and go to the word null-padder, which may eventually go to the byte
- null-padder.

- procedure strrchr (optimized assembler version for the 80960K series)
-
- src_addr = strrchr (src_addr, char)
-
- return a pointer to the last byte that contains the indicated
- byte in the source string. Return null if the byte is not found.
-
- Undefined behavior will occur if the end of the source string (i.e.
- the terminating null byte) is in the last two words of the program's
- allocated memory space. This is so because strrchr fetches ahead.
- Disallowing the fetch ahead would impose a severe performance penalty.
-
- Strategy:
-
- Fetch the source string by words and scanbyte the words for the
- char until either a word with the byte is found or the null byte is
- encountered. In the former case, move through the word to find the
- matching byte and save its memory address, then continue the search.
- In the latter case, return the saved address, or zero (null) if none
- was ever found to save.
-
- Tactics:
-
- 1) Do NOT try to fetch the words in a word aligned manner because,
- in my judgement, the performance degradation experienced due to
- non-aligned accesses does NOT outweigh the time and complexity added
- by the preamble that would be necessary to assure alignment. This
- is supported by the intuition that most source arrays (even more
- true of most big source arrays) will be word aligned to begin with.
