Return type std::enable_if_t

[Gaetano Mendola]

cppcheck (2.8) is not able to understand that a return type declared as:

std::enable_if_t<sizeof(uint64_t_==8> is void.</sizeof(uint64_t_==8>

Example:

#include <type_traits>
#include <stdint.h>

std::enable_if_t<sizeof(uint64_t)==8>
foo() {
}

int main() {
  foo();
}

cppcheck reports: Found a exit path from function with non-void return type that has missing return statement

note that if the return type is declared as:

std::enable_if<sizeof(uint64_t)==8>::type then cppcheck recognize the return type as void.</sizeof(uint64_t)==8>
