Description Ian Romanick 2010-08-17 16:11:10 UTC 
piglit test cases glsl-mat-from-int-ctor-* attempt to construct matrices and compare them with expected values.  These tests fail seemingly because the matrix comparisons are not broken down into vector operations.  This results in a assertion failure in ir_to_mesa:

shader_runner: program/ir_to_mesa.cpp:727: virtual void ir_to_mesa_visitor::visit(ir_expression*): Assertion `!ir->operands[operand]->type->is_matrix()' failed.
