IVy is a research tool intended to allow interactive development of protocols and their proofs of correctness and to provide a platform for developing and experimenting with automated proof techniques. In particular, IVy provides interactive visualization of automated proofs, and supports a use model in which the human protocol designer and the automated tool interact to expose errors and prove correctness.

Incorrect "wrong number of input parameters" error #54

Open ArneVogel opened 2 years ago

Hello,

I was checking out the toy_consensus.ivy from the examples: https://github.com/kenmcmil/ivy/blob/master/doc/examples/toy_consensus.ivy

When trying to compile the example to cpp I get the following error:

$ ivy_to_cpp target=test isolate=iso_impl toy_consensus.ivy 
toy_consensus.ivy: line 217: error: wrong number of input parameters

which references a call to shim.bcast call shim.bcast(self,msg);. Which is defined as follows:

    action bcast(src:node,m:msg)

Which seems to take two input parameters? When changing the call from call shim.bcast(self,msg); to either call shim.bcast(self); or call shim.bcast(self,msg,msg); I get the following errors:

toy_consensus.ivy: line 217: error: wrong number of input parameters (got 1, expecting 2)
toy_consensus.ivy: line 217: error: wrong number of input parameters (got 3, expecting 2)

When commenting out the call in line 217, ivy_to_cpp successfully compiles to cpp. Even though there are other calls to shim.bcast in the file with two arguments, e.g. in lines 233 call shim.bcast(self,reply);
