pre

1. test with hexrays 7.3(x86), hexrays 7.2(x64)

2. do not run with hexrays 7.0, IDA will crash

usage

1. flod code: {} block, case block

1. code match: TODO
2. simplify c++ decompiled code: TODO

c++

1. operator

v1 = operator<<(&std::cout, string<<3);
v2 = &std::endl;
v3 = operator<<(v1, v2);
=> 
v1 = {&std::cout << (string << 3)};
v2 = &std::endl;
v3 = {v1 << v2};
==> v3 = {&std::cout << (string << 3) << &std::endl};

2. template
3. override
4. vtable
