Re: [csmith-dev] Random configuration file for csmith

Thanks Yang.

I have another question on group configuration. As described in doc/probabilities.txt (e.g., statement_prob), seems there is 15% chance to get statement_ifelse (55%-40%). However, in the latest generated sample configure file by csmith, statement_assign_prob=100, statement_block_prob=0. Does it mean only -100% chance to get statement_block_prob?

Also, what is the difference between [statement_prob,...] and (assign_binary_ops_prob,...)? Does the latter have the same rule as the former?

Thanks,
Haihao

Hi,

csmith provided the interface to take configure file as input to generate different kinds of test cases. However, there is lack of documentation to describe how to set the value of configure parameter.

doc/probabilities.txt describes the format of probability configurations.

For example, I don't know whether different items in configure file have dependencies. I don't know whether all the values could range from 0 to 100.

I am wondering whether there is any empirical data for random configuration.

Sorry, we don't have that data.
