Author : ningerso
Project : e17
Module : libs/evas
Dir : e17/libs/evas/src/lib/canvas
Modified Files:
evas_font_dir.c
Log Message:
Did some cache miss profiling with a large number of transient text objects
and found that reordering the evas list containing the font path list was
actually hurting cache performance. Frequent cache misses occurred in
evas_mempool_free in it's main loop. So removing the list node and re adding it
actually decreased cache performance in some cases. This would also cause memory
allocation bouncing if mempools were not used.
Added evas_list_promote_list to move a list node to the beginning of a list.
Changed reordering lists to use evas_list_promote_list.
