v3_core: Suppress compiler-generated calls in guards
Compiling the following function: f(V) when not (bar and V) -> true; %Line 4 f(_) -> false. would produce the following warnings: no_file: Warning: the call to is_boolean/1 has no effect t.erl:4: Warning: the guard for this clause evaluates to 'false' t.erl:4: Warning: use of operator '=:=' has no effect Two of the warnings refer to calls to is_boolean/1 and '=:='/2 which v3_core added when translating the code to Core Erlang. The only relevant warning is: t.erl:4: Warning: the guard for this clause evaluates to 'false' Suppress the other two warning by marking the compiler-generated calls with a 'compiler_generated' annotation.
