But the names appear in all the gimple, ipa? and rtl dumps after that, so
if it e.g. just printed a SRA uid -> DECL uid mapping in tree-sra*-details
dump, then one would not have it easily accessible when looking all the
other dumps.
If it is just guarded with flag_dump_final_insns != NULL, then we have the
previous behavior almost all the time, just for -fcompare-debug effectively
force -nouid flag into all the dumps for the fancy names. But it is easy
to just remove that flag from the command line to have more details, IMHO
that is better than just looking up some mapping dump somewhere.
