Ron Yorston	bcf91d2760	libbb: code shrink and speed up index_in_strings() Rewrite index_in_strings() to replace calls to strcmp()/strlen(). With this change searching for valid names in the applet_names array (for example) is 40% faster. The code has to assume the strings aren't sorted, so will always scan the entire array when presented with an invalid name. function old new delta index_in_strings 63 56 -7 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-7) Total: -7 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2021-02-02 14:37:37 +01:00
Ron Yorston	59120c3303	libbb: code shrink and speed up find_applet_by_name() find_applet_by_name() determines the appropriate range of applet indices to check for the given name and performs a linear search in applet_names[]. Revise the code so the index of the upper bound of the range, 'max', isn't calculated. Instead check the value of the first non-matching character to see if we've reached the end of the range. This new code speeds up the time to find a valid applet name by 6% and halves the time to detect that a given name is invalid. The average time to detect an invalid name is now the same as for a valid one. function old new delta find_applet_by_name 155 133 -22 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-22) Total: -22 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2021-02-02 14:16:38 +01:00
