Author: Kees J. Bot - 2 Jan 1994 - -Remarks. - All routines set up proper stack frames, so that stack traces can be - derived from core dumps. String routines are often the ones that - get the bad pointer. - - Flags are often not right in boundary cases (zero string length) on - repeated string scanning or comparing instructions. This has been - handled in sometimes nonobvious ways. - - Only the eax, edx, and ecx registers are not preserved, all other - registers are. This is what GCC expects. (ACK sees ebx as scratch - too.) The direction byte is assumed to be wrong, and left clear on - exit. - -Assumptions. - The average string is short, so short strings should not suffer from - smart tricks to copy, compare, or search large strings fast. This - means that the routines are fast on average, but not optimal for - long strings. - - It doesn't pay to use word or longword operations on strings, the - setup time hurts the average case. - - Memory blocks are probably large and on word or longword boundaries. - - No unaligned word moves are done. Again the setup time may hurt the - average case. Furthermore, the author likes to enable the alignment - check on a 486. - -String routines. - They have been implemented using byte string instructions. The - length of a string it usually determined first, followed by the - actual operation. - -Strcmp. - This is the only string routine that uses a loop, and not - instructions with a repeat prefix. Problem is that we don't know - how long the string is. Scanning for the end costs if the strings - are unequal in the first few bytes. - -Strchr. - The character we look for is often not there, or at some distance - from the start. The string is scanned twice, for the terminating - zero and the character searched, in chunks of increasing length. - -Memory routines. - Memmove, memcpy, and memset use word or longword instructions if the - address(es) are at word or longword boundaries. No tricks to get - alignment after doing a few bytes. No unaligned operations.
