Summary: [glsl2] Matrix comparison not implemented for
non-constants
Product: Mesa
Version: git
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: i...@freedesktop.org
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.
