Running the compilation with DTrace based profiled (instead of
rebuilding with profiling enabled) found the following top CPU
consumers:
__gnat_portable_no_block_spawn 994414500
system__os_lib__non_blocking_spawn 1002010800
make__compile_sources__compile.15427 1010527200
make__compile_sources__start_compile_if_possible.15545 1029687100
namet__name_chars__set_item 1248495500
snames__initialize 1710811700
namet__name_find 1750025500
So something strange seems to be happening in gcc/ada/named.adb
(Name_Find).
