commit    0f679f0ab5afc8c1469453b922d37ae7216136a4 (patch) (side-by-side diff)

glsl: Fix aggregates with dynamic initializers.

Vectors are falling in to the ir_dereference_array() path. 
Without this change, the following glsl aborts the debug driver, or gets the
wrong answer in release: 
mat2x2 a = mat2( vec2( 1.0, vertex.x ), vec2( 0.0, 1.0 ) ); 
Also submitting piglit tests, will reference in bug.

v2: Rebase on Mesa master. 
v3: Remove unneeded check for arrays, which are covered by
process_array_constructor(), recommended by Timothy Arceri.
