I remember we talked about content filtering dump flags. Things like
-fdump-xxx-ir <-- dump IR only
-fdump-xxx-transformation <-- optimization note
-fdump-xxx-debug <-- other debug traces
Other than that, now I think 'details' and 'all' seem redundant.
'verbose' flag/modifier can achieve the same effect depending on the
context.
-fdump-xxx-ir-verbose <-- dump IR, and turn on IR modifiers such as
vops, lineno, etc
-fdump-xxx-transforamtion-verbose <-- dump transformations + missed
optimizations + notes
-fdump-xxx-debug-verbose <-- turn on detailed trace.
