| // 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 |
| // only in this file, because the macrology requires single-token type names. |
| |
| // Note: Diagnostic options not meant for VM tuning or for product modes. |
| // They are to be used for VM quality assurance or field diagnosis |
| // of VM bugs. They are hidden so that users will not be encouraged to |
| // try them as if they were VM ordinary execution options. However, they |
| // are available in the product version of the VM. Under instruction |
| // from support engineers, VM customers can turn them on to collect |
| // diagnostic information about VM problems. To use a VM diagnostic |
| // option, you must first specify +UnlockDiagnosticVMOptions. |
| // (This master switch also affects the behavior of -Xprintflags.) |
| // |
| // experimental flags are in support of features that are not |
| // part of the officially supported product, but are available |
| // for experimenting with. They could, for example, be performance |
| // features that may not have undergone full or rigorous QA, but which may |
| // help performance in some cases and released for experimentation |
| // by the community of users and developers. This flag also allows one to |
| // be able to build a fully supported product that nonetheless also |
| // ships with some unsupported, lightly tested, experimental features. |
| // Like the UnlockDiagnosticVMOptions flag above, there is a corresponding |
| // UnlockExperimentalVMOptions flag, which allows the control and |
| // modification of the experimental flags. |
| // |
| // Nota bene: neither diagnostic nor experimental options should be used casually, |
| // and they are not supported on production loads, except under explicit |
| // direction from support engineers. |
| // |
| // manageable flags are writeable external product flags. |
| // They are dynamically writeable through the JDK management interface |
| // (com.sun.management.HotSpotDiagnosticMXBean API) and also through JConsole. |
| // These flags are external exported interface (see CCC). The list of |
| // manageable flags can be queried programmatically through the management |
| // interface. |
| // |
| // A flag can be made as "manageable" only if |
| // - the flag is defined in a CCC as an external exported interface. |
| // - the VM implementation supports dynamic setting of the flag. |
| // This implies that the VM must *always* query the flag variable |
| // and not reuse state related to the flag state at any given time. |
| // - you want the flag to be queried programmatically by the customers. |
| // |
| // product_rw flags are writeable internal product flags. |
| // They are like "manageable" flags but for internal/private use. |
| // The list of product_rw flags are internal/private flags which |
| // may be changed/removed in a future release. It can be set |
| // through the management interface to get/set value |
| // when the name of flag is supplied. |
| // |
| // A flag can be made as "product_rw" only if |
| // - the VM implementation supports dynamic setting of the flag. |
| // This implies that the VM must *always* query the flag variable |
| // and not reuse state related to the flag state at any given time. |
| // |
| // Note that when there is a need to support develop flags to be writeable, |
| // it can be done in the same way as product_rw. |
| // |
| // range is a macro that will expand to min and max arguments for range |
| // checking code if provided - see jvmFlagRangeList.hpp |
| // |
| // constraint is a macro that will expand to custom function call |
| // for constraint checking if provided - see jvmFlagConstraintList.hpp |
| // |
| // writeable is a macro that controls if and how the value can change during the runtime |
| // |
| // writeable(Always) is optional and allows the flag to have its value changed |
| // without any limitations at any time |
| // |
