// notproduct flags are settable / visible only during development and are not declared in the PRODUCT version
// A flag must be declared with one of the following types:
// bool, int, uint, intx, uintx, size_t, ccstr, double, or uint64_t.
// The type "ccstr" is an alias for "const char*" and is used
// bool, int, uint, intx, uintx, size_t, ccstr, ccstrlist, double, or uint64_t.
// The type "ccstr" and "ccstrlist" are an alias for "const char*" and is used
// only in this file, because the macrology requires single-token type names.
// Note: Diagnostic options not meant for VM tuning or for product modes.
