Given an instance of something that implements ghidra.program.model.listing.Function, and the register as a string (e.g. x0) how can I get the name of the argument (e.g. param1)?

1 Answer 1


The first way I found is (as Kotlin code)

function.parameters.first { it.variableStorage.register.toString() == "x0" }.name

i.e. go through the parameters and find the first (and hopefully only one), that has a storage location with the string representation x0.

This feels somewhat hacky, but should at least work. The whole expression type checks, so it should cover basically all cases, and I am not sure if there can ever be a case where somehow multiple parameters are stored in the same register that have the same string representation.
