Manual Flags

NameDescriptionDefault
random-initial-seed

Randomly initialize the initial seed on each final executable invocation This is useful for catching cases when you rely on (non-existent) stability of hashable's hash functions.

Disabled
Automatic Flags
NameDescriptionDefault
integer-gmp

Are we using integer-gmp to provide fast Integer instances? No effect on GHC-9.0 or later.

Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
