Depends on what you mean by "compiled".
.ads files are read by the compiler. No separate .o file is produced.
Yes, I see this now. Changing a .ads file does not trigger a recompile,
but changing the corresponding .adb file, the recompile encounters the
changes made also in the .ads file (similiar to a header file in C)
Similar in a way, but also quite different in that the compiler knows
about the dependencies between .ads and .adb files (and also between
different .ads files).
Changing an .ads file (in a significant way) should certainly trigger
recompilation of those .adb files that depend on the changed .ads file.
However, the Gnat compiler has some (optional) intelligence that can
avoid recompilation when a file is changed in an inessential way, for
example just in the comments.
