Cranelift: The clif-util run command seems can not find the entry function

[abc767234318]

I constructed a clif file.

multi_func21_fail_to_find_function.zip

I used the following command to run it.

clif-util run -v file_tests/multi_func21.clif

But I got the following error:

file_tests/multi_func21_fail_to_find_function.clif: 1: expected a function name, e.g. %my_fn
1 file
Error: 1 failure

On line 872 I specify the name of the function to run: And the definition of u1:0 is on line 764.

; print: u1:0()

I think you need to use a function name like %my_func instead of a function name like u1:0.

I think you need to use a function name like %my_func instead of a function name like u1:0.

The names of these functions are randomly generated, and they are named using numbers to facilitate subsequent analysis. In addition, other clif files I generated were named in a similar way and did not encounter this error.

if let Some(Token::Name(name)) = self.token() {

the code for parsing ; print directives expects a Token::Name for the name of the function. %my_func is tokenized as Token::Name. u1:0 is not tokenized as Token::Name however. Only tokens that start with %.

Thank you very much, I will close this issue.
