摘要： Accessing memory in an array includes performing a first instruction, including by determining whether an index used by the first instruction is within a valid range and in the event that the index is within a valid range, determining a memory address related to an array element that corresponds to the index. Accessing memory in the array further includes, in the event that the index is within a valid range, performing a second instruction to access the array element, the access being based at least in part on the memory address determined by the first instruction.
摘要翻译：访问阵列中的存储器包括执行第一指令，包括通过确定第一指令使用的索引是否在有效范围内，以及在索引在有效范围内的情况下，确定与阵列元素有关的存储器地址，对应于索引。如果索引在有效范围内，执行第二指令来访问数组元素，访问存储器还包括至少部分地基于由第一指令确定的存储器地址的访问。

摘要： Instruction execution includes fetching an instruction that comprises a first set of one or more bits identifying the instruction, and a second set of one or more bits associated with a first address value. It further includes executing the instruction to determine whether to perform a trap, wherein executing the instruction includes selecting from a plurality of tests at least one test for determining whether to perform a trap and carrying out the at least one test. The second set of one or more bits is used in the determination of whether to perform the trap; and the plurality of tests includes a matrix test that determines whether a data value being stored as pointed to by the first address value is escaping from one of a plurality of managed memory types to another one of the plurality of managed memory types and generates a trap in the event that the data value is determined to be escaping from one of the plurality of managed memory types to another one of the plurality of managed memory types, wherein the matrix test is based on a matrix associated with garbage collection and a matrix entry located using at least some of the first set of one or more bits and at least some of the second set of one or more bits.
