commit 2d577ee730c30caacf711babde6542766aa0b655 Author: Ian Romanick <ian.d.romanick@intel.com> Date: Mon Dec 13 15:42:46 2010 -0800 ir_to_mesa: Don't generate swizzles for record derefs of non-scalar/vectors This is the same as what the array dereference handler does. Fixes piglit test glsl-link-struct-array (bugzilla #31648). NOTE: This is a candidate for the 7.9 and 7.10 branches. commit 3501fd85942dc905de53710e3a57f16641e4e70d Author: Ian Romanick <ian.d.romanick@intel.com> Date: Mon Dec 13 15:42:46 2010 -0800 ir_to_mesa: Don't generate swizzles for record derefs of non-scalar/vectors This is the same as what the array dereference handler does. Fixes piglit test glsl-link-struct-array (bugzilla #31648). NOTE: This is a candidate for the 7.9 and 7.10 branches. (cherry picked from commit 2d577ee730c30caacf711babde6542766aa0b655) verified on 7.10 branch |

Below shader gets assertion program/ir_to_mesa.cpp:325: int swizzle_for_size(int): Assertion `(size >= 1) && (size <= 4)' failed. struct s { vec4 v[1]; float f; }; s a[1]; void main() { a[0].v[0] = vec4(0.0, 0.0, 0.0, 0.0); a[0].f = 1.0; gl_FragColor = vec4(0.0, a[0].f, 0.0 ,1.0); } Tested on Piketon (i965) with mesa master. New piglit case attached. Note both v and a needs to be array to trigger this issue.
