* tgsi: text parser: fix parsing of array in declarationDave Airlie2013-06-181-3/+9
| | | | | | | | | | | I noticed this code didn't work as advertised while doing some passing around of TGSI shaders and trying to reparse them, and things failing. This seems to fix it here for at least the small test case I hacked into a graw test. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

* draw: fix a regression in computing max eltZack Rusin2013-06-171-0/+1
| | | | | | | | | | | | | gl can use elts without setting indices, in which case our eltMax was set to 0 and always invoking the overflow condition. So by default set eltMax to maximum, it will be curbed by draw_set_indexes (if it ever comes) and if not then it will let gl's glVertexPointer/glDrawArrays work correctly.

* mesa: Fix bug in unclamped float to ubyte conversion.Manfred Ernst2013-06-122-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | We have to use pipe->blit, not resource_copy_region, so that the read buffer is resolved if it's multisampled. I also removed the CPU-based copying, which just did format conversion (obsoleted by the blit). Also, the layer/slice/face of the read buffer is taken into account (this was ignored).

* st/mesa: rework blit_copy_pixels to use pipe->blitMarek Olšák2013-06-131-35/+79
| | | | | | | | | | | | | | | There were 2 issues with it: - resource_copy_region doesn't allow different sample counts of both src and dst, which can occur if we blit between a window and a FBO, and the window has an MSAA colorbuffer and the FBO doesn't. (this was the main motivation for using pipe->blit) - blitting from or to a non-zero layer/slice/face was broken, because rtt_face and rtt_slice were ignored. blit_copy_pixels is now used even if the formats and orientation of framebuffers don't match.

* glsl: Generate smaller values for uniform locationsIan Romanick2013-06-121-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we would generate uniform locations as (slot << 16) + array_index. We do this to handle applications that assume the location of a[2] will be +1 from the location of a[1]. This resulted in every uniform location being at least 0x10000. The OpenGL 4.3 spec was amended to require this behavior, but previous versions did not require locations of array (or structure) members be sequential. We've now encountered two applications that assume uniform values will be "small." As far as we can tell, these applications store the GLint returned by glGetUniformLocation in a int16_t or possibly an int8_t. THIS BEHAVIOR IS NOT GUARANTEED OR IMPLIED BY ANY VERSION OF OpenGL. Other implementations happen to have both these behaviors (sequential array elements and small values) since OpenGL 2.0, so let's just match their behavior. Fixes "3D Bowling" on Android.
