Assisted garbage collection in a virtual machine

A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:

• receiving, by the processing device executing a virtual machine, bytecode comprising an object to be loaded into a memory space, the object being tagged with a garbage collection descriptor, wherein the garbage collection descriptor is generated according to an annotation to the object in a source code;
• determining, in view of the garbage collection descriptor, a region of the memory space to store the object, wherein the memory space comprises a first region to store a first set of objects that have survived less than a pre-determined number of rounds of garbage collection and a second region that is to store a second set of objects survived at least the pre-determined number of rounds of garbage collection in the first region;
• and
• storing the object in the region of the memory space.

A system comprising:

• a memory;
• and
• a processing device, operationally coupled to the memory, to execute a virtual machine, the processing device to:
• receive bytecode comprising an object to be loaded into a memory space, the object being tagged with a garbage collection descriptor, wherein the garbage collection descriptor is generated according to an annotation to the object in a source code;
• determine, in view of the garbage collection descriptor, a region of the memory space to store the object, wherein the memory space comprises a first region to store a first set of objects survived less than a pre-determined number of rounds of garbage collection and a second region to store a second set of objects survived at least the pre-determined number of rounds of garbage collection in the first region;
• and
• store the object in the region of the memory space.
