摘要： A program feature set is compared to a processor feature set. The comparison may be performed in response to restoring the program onto a system or requesting its execution. The processor feature set represents zero, one or more optional hardware features supported by the processor, whereas the program feature set represents zero, one or more optional hardware features the program relies upon in its generated code. Comparison of the feature sets determines whether a particular program may run on a particular processor. Programs may be automatically or manually rebuilt to achieve full compatibility. If the comparison indicates that the program requires a feature not supported by the processor, the program is rebuilt based on the processor feature set. Alternatively, the program may be rebuilt in response to a rebuild request, rather than the comparison. The program is preferably rebuilt from an intermediate representation (IR) stored with or locatable from the program.

摘要： An apparatus and method selectively invalidate entries in an address translation cache instead of invalidating all, or nearly all, entries. One or more translation mode bits are provided in each entry in the address translation cache. These translation mode bits may be set according to the addressing mode used to create the cache entry. One or more “hint bits” are defined in an instruction that allow specifying which of the entries in the address translation cache are selectively preserved during an invalidation operation according to the value(s) of the translation mode bit(s). In the alternative, multiple instructions may be defined to preserve entries in the address translation cache that have specified addressing modes. In this manner, more intelligence is used to recognize that some entries in the address translation cache may be valid after a task or partition switch, and may therefore be retained, while other entries in the address translation cache are invalidated.

摘要翻译： 一种装置和方法选择性地使地址转换高速缓存中的条目无效，而不是使所有或几乎所有条目无效。 在地址转换高速缓存中的每个条目中提供一个或多个翻译模式位。 可以根据用于创建高速缓存条目的寻址模式来设置这些转换模式位。 在指令中定义一个或多个“提示位”，该指令允许根据翻译模式位的值来指定在无效操作期间选择性地保留地址转换高速缓存中的哪些条目。 在替代方案中，可以定义多个指令以保留具有指定寻址模式的地址转换高速缓存中的条目。 以这种方式，使用更多的智能来识别地址转换高速缓存中的一些条目在任务或分区切换之后可能是有效的，并且因此可以被保留，而地址转换高速缓存中的其他条目是无效的。

摘要： An operating system kernel includes an attach mechanism and a detach mechanism. In addition, processes are tagged with an access attribute identifying the process as either a client process or a server process. Based on the access attribute, the operating system kernel lays out the process local address space differently depending on whether the process is a client process or a server process. A server process can “attach” to a client process and reference all of the client process' local storage as though it were its own. The server process continues to reference its own process local storage, but in addition, it can reference the other storage, using the client process' local addresses. When access to the other storage is no longer needed, the server process can “detach” from the client process. Once detached, the other storage can no longer be referenced.
