ALWAYS_ASSERT_EQUAL

#define ALWAYS_ASSERT_EQUAL	(		x,
			y,
			msg
	)

Value:

{                                      \
auto v1=(x);                           \
auto v2=(y);                           \
if(v1 != v2) {                         \
    THROW_EXCEPTION(std::invalid_argument, msg, v1, v2); \
}}

This macro adds a check that two values are equal. This check is added both in debug and release mode. If the check fails, a std::invalid_argument exception is raised with the given message. The message should contain two placeholders {} which will be filled with the two values.

THROW_EXCEPTION

#define THROW_EXCEPTION	(		exception_type,
			...
	)

Value:

    [&]() __attribute__((cold, noreturn)) { \
    throw exception_type( fmt::format(__VA_ARGS__) ); \
}();

this is a utility macro that wraps the formatting of an error message and throwing of std::runtime_error into an immediately-executed lambda that is marked with the cold attribute. This can help the optimizer.
