ABSTRACT:
The invention relates to managing registers during a binary translation mode in a virtual computing system. A set of registers is saved to memory before beginning to execute a series of blocks of translated code, and the contents of the set of registers are restored from memory later. A status register is maintained for tracking the status of each register within the set, the status indicating whether the contents are valid and whether the contents are saved in memory. Before the execution of each block, a determination is made as to whether the actions taken within the block relative to the registers are compatible with the current status of the registers. If the actions are not compatible, additional registers are saved to memory or restored from memory, so that the translation block can be executed.
