[MLton-user] Explosion in MLton compilation time

[David Hansel]

Hi,

Thanks for your response.  We understand of course that diagnosing this
issue without access to the source code will be hard.  We appreciate any help
you can provide in either tracking down the root cause of this issue or
possible workarounds.

What kind of consequences should we expect from using those flags?  Are
those passes an important part of the optimizations MLton does to the code
or are the improvements usually rather minor?

Best regards,
