From 35fd61bd99c15c2e13d3945b41c4db7df6e64319 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 6 Nov 2012 23:18:41 -0800 Subject: mesa: Import a copy of the open-addressing hash table code I wrote. Mesa's chaining hash table for object names is slow, and this should be much faster. I namespaced the functions under _mesa_*, to avoid visibility troubles that we may have had before with hash_table_* functions. v2: Move .c file to main/, const a few things, clean up loop conditions, add/extend some comments.
