[isabelle-dev] Data slots for runtime compiler invocation

[Florian Haftmann]

Recently I changed the interface for invoking the compiler at runtime on
generated code to use proof data slots rather than unsychronized
references.  The consequence is that there are a lot of non-joinable
proof data slots laying around in the same module, cf.
http://isabelle.in.tum.de/reports/Isabelle/rev/f6ab14e61604

Maybe it would be better to avoid proof data slots entirely in that case
any use thread-local state variables or something like that?  The
crucial issue is that compiler invocation essentially is a function of
type string -> unit but somehow a result has to be returned, which must
occur through a side effect.
