I do see it before the offending commit though so this is something that has existed before. For some reason I did not spot these in HSW. That test eventually crashes on HSW but passes on KBL with this single warning. --- 8< --- ==12320== Memcheck, a memory error detector ==12320== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==12320== Using Valgrind-3.14.0 and LibVEX; rerun with -h for copyright info ==12320== Command: bin/shader_runner /home/tpalli/slow.shader_test -auto ==12320== ==12320== Conditional jump or move depends on uninitialised value(s) ==12320== at 0xC2A36FC: ra_get_best_spill_node (register_allocate.c:960) ==12320== by 0xBF99499: fs_reg_alloc::choose_spill_reg() (brw_fs_reg_allocate.cpp:937) ==12320== by 0xBF9A0A8: fs_reg_alloc::assign_regs(bool, bool) (brw_fs_reg_allocate.cpp:1161) ==12320== by 0xBF9A3AA: fs_visitor::assign_regs(bool, bool) (brw_fs_reg_allocate.cpp:1201) ==12320== by 0xBF619A7: fs_visitor::allocate_registers(unsigned int, bool) (brw_fs.cpp:7282) ==12320== by 0xBF62D20: fs_visitor::run_fs(bool, bool) (brw_fs.cpp:7694) ==12320== by 0xBF63CC8: brw_compile_fs (brw_fs.cpp:8028) ==12320== by 0xB7BCE62: brw_codegen_wm_prog (brw_wm.c:123) ==12320== by 0xB7BE25D: brw_fs_precompile (brw_wm.c:592) ==12320== by 0xB7A423C: brw_shader_precompile(gl_context*, gl_shader_program*) (brw_link.cpp:56) ==12320== by 0xB7A541F: brw_link_shader (brw_link.cpp:374) ==12320== by 0xBAC983D: _mesa_glsl_link_shader (ir_to_mesa.cpp:3170) ==12320==</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
