commit ff79633d9f930e396933a0ad9564824ec73ea4dc Author: Eric Anholt <eric@anholt.net> Date: Tue Nov 30 11:23:28 2010 -0800 glsl: Fix structure and array comparisions. We were trying to emit a single ir_expression to compare the whole thing. The backends (ir_to_mesa.cpp and brw_fs.cpp so far) expected ir_binop_any_nequal or ir_binop_all_equal to apply to at most a vector (with matrices broken down by the lowering pass). Break them down to a bunch of ORed or ANDed any_nequals/all_equals. Fixes: glsl-array-compare glsl-array-compare-02 glsl-fs-struct-equal glsl-fs-struct-notequal Bug #31909 mesa: 9e1fbd3d6e2a8accd0ebdc5937dd6eb7a8ef9b10 (master) piglit glsl-array-compare-02 test passes. |
