| * | tgsi: fix mixed data type comparison in tgsi_point_sprite.c | Charmaine Lee | 2016-06-06 | 1 | -3/+3 |
| | | | | | | | | | | | | | | | | | Cast the unsigned semantic index to integer datatype before comparing to max_generic, otherwise, max_generic which is initialized to -1 will be converted to unsigned int before the comparison, causing a wrong semantic index to be assigned to a shader output. Fixes the assert running TurboCAD_gl.trace. (VMware bug 1667265) Also tested with glretrace, mesa demos pointblast, spriteblast and pointcoord. v2: use the original max_generic variable but add the (int) cast to the semantic index, as suggested by Brian.

| * | tgsi: adds tgsi utility to transform a shader to support point sprite | Charmaine Lee | 2015-09-01 | 1 | -0/+582 |
| This adds a tgsi utility tgsi_add_point_sprite to transform a geometry shader to emulate wide points by drawing quads. This utility adds an extra output for the original point position if the point position is to be written to a stream output buffer. It also assumes the driver will add a constant for inverse viewport scale after the user defined constants. Reviewed-by: Brian Paul <brianp@vmware.com> | |||||
