Wilco Dijkstra 284f42bc77 Simplify and speedup strstr/strcasestr first match ... Looking at the benchtests, both strstr and strcasestr spend a lot of time in a slow initialization loop handling one character per iteration. This can be simplified and use the much faster strlen/strnlen/strchr/memcmp. Read ahead a few cachelines to reduce the number of strnlen calls, which improves performance by ~3-4%. This patch improves the time taken for the full strstr benchtest by >40%. * string/strcasestr.c (STRCASESTR): Simplify and speedup first match. * string/strstr.c (AVAILABLE): Likewise.		2018-08-03 17:24:12 +01:00
