Make -fbyte-code prevent unboxed tuples/sums from implying object code (#16876)
This resolves #16876 (closed) by making the explicit use of -fbyte-code
prevent code that enables UnboxedTuples
or UnboxedSums
from
automatically compiling to object code. This allows for a nice
middle ground where most code that enables UnboxedTuples
/-Sums
will still benefit from automatically enabling -fobject-code
, but
allows power users who wish to avoid this behavior in certain corner
cases (such as lens
, whose use case is documented in #16876 (closed)) to do
so.
Along the way, I did a little cleanup of the relevant code and documentation:
-
enableCodeGenForUnboxedTuples
was only checking for the presence ofUnboxedTuples
, butUnboxedSums
has the same complications. I fixed this and renamed the function toenableCodeGenForUnboxedTuplesOrSums
. - I amended the users' guide with a discussion of these issues.
