(gimple_gen_ior_profiler): Likewise. * value-prof.c (dump_histogram_value): Use default in switch statement instead of HIST_TYPE_MAX. (stream_in_histogram_value): Likewise. (gimple_duplicate_stmt_histograms): Do not use NULL for implicitly set arguments. (gimple_divmod_values_to_profile): Do not use reserve+quick_push. (gimple_indirect_call_to_profile): Likewise. (gimple_find_values_to_profile): Use implicit function call arguments. * value-prof.h (gimple_alloc_histogram_value): Set default values. (gimple_gen_interval_profiler): Remove last argument.
