Abstract

In this paper we present Solemn, a new user-level simulation mode for Sparc Sulima, a SPARC V9 complete machine simulator. Solemn extends Sparc Sulima allowing it to simulate at user-level an unmodified Solaris executable: 32 or 64-bit, and statically or dynamically linked. This yields some advantages over both complete machine simulators and traditional system call emulation. To do this, Solemn manages the virtual address space and files that the simulated program requires, and intercepts and emulates system call traps. Another novel feature is the emulation of memory mapped files. We describe some of the implementation details of Solemn, including its memory management architecture and portability.
