New Revision: 2477
URL: http://svn.gnome.org/viewvc/gegl?rev=2477&view=rev
Log:
Extended the gegl-chanting and the build system to easily allow
defining an alternate process function that will be compiled to mmx
and sse by gcc, coupled with runtime cpu detection at class init time
to determine which variant to use.
* configure.ac: make USE_SSE available to makefiles.
* gegl/Makefile.am: install gegl-cpuaccel.h
* gegl/gegl-chant.h: added logic to detect various SIMD compile modes,
generating different .o 's based on compiler flags.
* gegl/gegl-plugin.h: include gegl-cpuaccel.h
* operations/Makefile-operations.am: added separete recipe for
compiling .c files that contains the string GEGL_SIMD.
* operations/common/brightness-contrast.c:
* operations/common/invert.c:
* operations/generated/other-blend.rb:
* operations/generated/svg-12-porter-duff.rb: The rest, updated to
specify their SIMD code using GEGL_SIMD.
