Hi Daniel, In no particular order: 1) You rock 2) If no one beats me to it I'll send some numbers to the list tomorrow with the patches tested on ARM hardware 3) If you don't get a 770 for Christmas there is no justice in this world :) Cheers, Xan <div>On 11/21/06, Daniel Amelang <<a href="mailto:daniel.amelang@gmail.com">daniel.amelang@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Ok, after rounding and glyph transforming dropped off the softfloat profile, _cairo_fixed_from_double showed up again (even with the new optimization). Most of these calls came from _cairo_matrix_to_pixman_matrix, and luckly, most of the time, the matrix being converted was an identity matrix, so we can easily solve this one by adding a quick check for an identity matrix, and do a fast memcpy from a template pixman identity matrix to perform the conversion. Again, I need someone with a Nokia 770 to perform the real test. Sorry. If I weren't living off student loans at the moment, I buy one in a heartbeat. Maybe Santa Claus thinks I've been a good boy this year... On a side note, I have laying around a version of _cairo_fixed_from_double doesn't have any FP operations at all. Once I clean it up, I'll submit the patch. Thing is, it slows down systems that _do_ have a FPU, so we''ll have to come up with some sort of --avoid-fp configure flag to enable paths that run faster on FP crippled systems, but slower on those that have an FPU. Either way, it's nice to get _cairo_fixed_from_double entirely off FP, and thus far away from the top of any profile on softfloat.
