================
Comment at: clang/test/Sema/warn-strict-prototypes.m:20
+ // know it's a block when diagnosing.
+ void (^block2)(void) = ^void() { // expected-warning {{a function
declaration without a prototype is deprecated in all versions of C}}
};
----------------
This is a definition, so the compiler knows that there are no parameters. Why
would we warn here? Reading
https://discourse.llvm.org/t/rfc-enabling-wstrict-prototypes-by-default-in-c/60521/18
it looks to me like an example of what @rnk was referring to, about churning
code to add `(void)` and then return back to `()` later.
