I've been playing around with it a bit and noticed some possible short comings, probably due to my lack of knowledge. It seems every time you call the orc generated function there is some overheard that makes it perform no better than straight C code for simple stuff. Like for example this function that adds a scalar value to an array of float. .function add_scalar .dest 4 dst float .source 4 src float .floatparam 4 val addf dst, src, val is slower then simply doing something like for(int i=0; i < N; i++)       data[i] += val; An example of the execution time for 100,000 loops are: orc: 26.264 ms normal: 0.47 ms </div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"> <div style="font-family: arial,helvetica,sans-serif; font-size: 13px;"><hr size="1">From: Mattijs Janssens <m.janssens@opencfd.co.uk> To: liboil@lists.freedesktop.org Sent: Wed, 9 March, 2011 2:56:36 AM Subject: Re: [Liboil] Simple scalar operations in ORC possible?
