I tested this against an older version of master; going to replace the
last line with
if (screen->get_param(screen, PIPE_CAP_TGSI_FS_POSITION_IS_SYSVAL)) {
pos = ureg_DECL_system_value(ureg, TGSI_SEMANTIC_POSITION, 0);
} else {
pos = ureg_DECL_fs_input(ureg, TGSI_SEMANTIC_POSITION, 0,
TGSI_INTERPOLATE_LINEAR);
}
Cheers,
Nicolai
