found a rendering bug in your sse3 code. _op_blend_c_dpan_sse3 <- or more specifically that its #defined to equate to _op_blend_c_dp_sse3(). rendering bug can be seen in this app: http://www.enlightenment.org/~raster/ello-0.1.0.0.tar.gz notice the text has overflowed pixel values (green garbage where it should be orange) if sse3 (or you re-enable the function i just disabled in svn in op_blend_color_sse3.c). same with the orange rectangle - it goes green if that sse3 routine is on. so for now that code path is disabled, probably dropping speed somewhat. > On Sun, Oct 02, 2011 at 08:32:50PM +0900, Carsten Haitzler wrote: > > On Sat, 1 Oct 2011 10:12:11 -0700 Jim Kukunas > > <james.t.kuku...@linux.intel.com> said: > > > > ok. big problems with sse3 on 32bit. we have to have it disabled. why? you > > did it with intrinsics, and intrinsics fail without -msse3, BUT... -msse3 > > builds code OPTIMIZED for sse3 - ie produces sse3 instructions even for > > regular c code. this means people compile evas and then have an x86 cpu > > incapable of sse3.. and presto. that binary doesnt work. that pretty much > > breaks backwards compatibility for x86 - packagers will have our throats > > for this. > > > > so this is all bad. the runtime sse3 tests are pointless and moot as long as > > we compile with -msse3. > > > > so we need sse3 asm that doesnt rely on -msse3 - ie like the mmx/sse was > > done. via macros that add real inlined assembly. :) > > Darn.
