Comment (by elaforge):

 Sorry about the delay, I guess trac doesn't email me when tickets are
 updated.

 The desired end result is that I have a bunch of .o files compiled with
 -O, and I need to load them into the GHC API.  Similarly, I have a set of
 .o files compiled with -fhpc, and I need to load them into ghci.  Any
 solution that reaches that result will probably work for me!

 I don't understand this, ghci already ignores -O and -fhpc, and as far as
 I know always has, whether or not people want to use them.  So the request
 is to continue ignoring those flags as always, but to be able to load
 files compiled with them... which presumably means include them in the
 hash.
