* mesa: Fix bug in unclamped float to ubyte conversion.Manfred Ernst2013-06-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The IEEE float optimized version of UNCLAMPED_FLOAT_TO_UBYTE in macros.h computed incorrect results for inputs in the range 0x3f7f0000 (=0.99609375) to 0x3f7f7f80 (=0.99803924560546875) inclusive. 0x3f7f7f80 is the IEEE float value that results in 254.5 when multiplied by 255. With rounding mode "round to closest even integer", this is the largest float in the range 0.0-1.0 that is converted to 254 by the generic implementation of UNCLAMPED_FLOAT_TO_UBYTE. The IEEE float optimized version incorrectly defined the cut-off for mapping to 255 as 0x3f7f0000 (=255.0/256.0). The same bug was present in the function float_to_ubyte in u_math.h. Fix: The proposed fix replaces the incorrect cut-off value by 0x3f800000, which is the IEEE float representation of 1.0f. 0x3f7f7f81 (or any value in between) would also work, but 1.0f is probably cleaner. The patch does not regress piglit on llvmpipe and on i965 on sandy bridge.

* mesa: Change "BRIAN PAUL" to "THE AUTHORS" in license text.Kenneth Graunke2013-04-231-1/+1

I believe that was already the sensible interpretation, but spelling it out is probably better. More practically, it also prevents people from accidentally copy & pasting the license into a new file which says Brian is not liable when he isn't even one of the authors.

* Consolidate some redundant definitions of ARRAY_SIZE() macro.Paul Berry2013-02-081-0/+3
| | | | | | | | | | | | | | | | | | | | | Previous to this patch, there were 13 identical definitions of this macro in Mesa source. That's ridiculous. This patch consolidates 6 of them to a single definition in src/mesa/main/macros.h. Unfortunately, I wasn't able to eliminate the remaining definitions, since they occur in places that don't include src/mesa/main/macros.h: - include/pci_ids/pci_id_driver_map.h - src/egl/drivers/dri2/egl_dri2.h - src/egl/main/egldefines.h - src/gbm/main/backend.c - src/gbm/main/gbm.c - src/glx/glxclient.h - src/mapi/mapi/stub.c I'm open to suggestions as to how to deal with the remaining redundancy.

* vbo: fix glVertexAttribI* functionsMarek Olšák2012-11-061-0/+39
| | | | | | | | | | | | | | | | | | | | | | The functions were broken, because they converted ints to floats. Now we can finally advertise OpenGL 3.0. ;) In this commit, the vbo module also tracks the type for each attrib in addition to the size. It can be one of FLOAT, INT, UNSIGNED_INT. The little ugliness is the vertex attribs are declared as floats even though there may be integer values. The code just copies integer values into them without any conversion. This implementation passes the glVertexAttribI piglit test which I am going to commit in piglit soon. The test covers vertex arrays, immediate mode and display lists. NOTE: This is a candidate for the stable branches. Reviewed-by: Brian Paul <[email protected]> v2: cosmetic changes as suggested by Brian

| | | | | | | | | | signbit() appears to be available everywhere (even MSVC according to MSDN), so let's use it instead of open-coding some messy and confusing bit twiddling macros.
