Finish the Identifier semantic action

[julianbraha]

From nmap/libssh2/src/, running

java superc.SugarC -D HAVE_CONFIG_H -I ../include/ -I ../src ${SUGARC_EVALUATION}/nmap/openssl.headless.c > openssl.desugared.c

results in ERROR: unsupported semantic action: Identifier.

Can you provide a code snippet to evaluate this on?

[julianbraha]

I will try to narrow down the cause of this in the original file, and create a small example

[julianbraha]

Here's an example:

void function(x)
{
}

This looks like a K&R-style function declaration. I'm realizing now that the original function was not like this, it's just that the type of the argument was a typedef, which was missing. In other words, this same error appears for a function like this:

void function(missing_typedef x)
{
}

This isn't actually a K&R-style function, it's just superc thinking that missing_typedef is the parameter's identifier rather than the type.

Is this a problem then with the headers?

[julianbraha]

Yes, and I should be able to proceed without this semantic action being finished. We may want an additional error message in the identifier semantic action to let the user know that superc was unable to proceed because there was either a missing typedef/#define or a K&R-style function.
