r600: compare structure elements instead of doing a memcmp
Structures might be padded by the compiler and these padding bytes remain un-initialized which in turn makes memcmp return a difference where from the logical point of view there is none. Fixes valgrind: Conditional jump or move depends on uninitialised value(s) at 0x4C32CBA: __memcmp_sse4_1 (vg_replace_strmem.c:1099) by 0xB8D2537: r600_set_vertex_buffers (r600_state_common.c:573) by 0xB71D44A: u_vbuf_set_driver_vertex_buffers (u_vbuf.c:1129) by 0xB71F7BB: u_vbuf_draw_vbo (u_vbuf.c:1153) by 0xB3B92CB: st_draw_vbo (st_draw.c:235) by 0xB36B1AE: vbo_draw_arrays (vbo_exec_array.c:391) by 0xB36BB0D: vbo_exec_DrawArrays (vbo_exec_array.c:550) by 0x10A989: piglit_display (textureSize.c:157) by 0x4F8F174: run_test (piglit_fbo_framework.c:52) by 0x4F7BA12: piglit_gl_test_run (piglit-framework-gl.c:229) by 0x10A60A: main (textureSize.c:71) Uninitialised value was created by a stack allocation at 0xB3948FD: st_update_array (st_atom_array.c:388) Signed-off-by: Gert Wollny <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
