dependence.c (dependence_string, [...]): Hide unused identifiers.
* dependence.c (dependence_string, direction_string,
dump_one_node, dump_node_dependence): Hide unused identifiers.
(get_low_bound, normalize_coefficients): Match definition to
static prototype.
(get_one_coefficient): Initialize variables `value0_is_idx' and
`value1_is_idx'.
(ziv_test, gcd_test): Mark parameters with ATTRIBUTE_UNUSED.
(ziv_test): Delete variable `idx', use parameter `sub' instead.
(direction_merge): Avoid automatic aggregate initialization.
(have_dependence_p): Use `src' not `dest' to set `src_idx'.
Initialize variables `dest_idx' and `src_idx'.
(end_dependence_analysis): Avoid C89 style function definition.
