摘要:
Various embodiments include nested emulation for a source application and source emulator. Duplicate source ISA libraries redirect the source emulator library calls to a target library, thereby forcing the native emulator through proper emulation channels between first and second ISAs. Other embodiments concern accelerating dynamic linking by determining certain function calls that, rather than being processed through emulation of PLT code, are instead directly called without the need for PLT code translation. Some embodiments address both nested emulation and accelerated dynamic linking but other embodiments include one of nested emulation and accelerated dynamic linking. Other embodiments are described herein.
摘要:
One embodiment pre-builds translations of kernel functions (KFs) and loads them into a translation pool and corresponding indexed table. The KFs are thus quickly loaded and do not necessarily await trapping and emulation via a LIB emulator. This results in faster access to KFs. Other embodiments provide hybrid emulation where some application functions (e.g., those that need quick performance) are translated from a source ISA library while other applications functions are processed via emulation to a target ISA library. Doing so provides faster access to certain functions. Other embodiments are described herein.
