From 9feb637cd0ea77f1ef232153daf9d9fd30bccd3d Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Thu, 30 Oct 2014 14:35:00 +0800 Subject: [PATCH] ilo: use a dynamic array for global bindings Use util_dynarray in ilo_set_global_binding() to allow for unlimited number of global bindings. Add a comment for global bindings.
