"sysexit" is disassembled incorrectly

What version of DynamoRIO are you using? 2.0.0-6 What operating system version are you running on? Linux x86-64

The attached test program attempts to decode, disassemble, and print a single SYSEXIT instruction. The program must be built and run on a 64-bit host, but assumes the instruction to be decoded is as though run on a 32-bit machine (hence the call to set_x86_mode()). The output from this code is:

sysexit -> %rsp

It should be:

sysexit -> %esp

seeing as 32-bit machines don't have a register called "rsp" (so far, SYSEXIT is the only instruction I've run into that suffers from this problem).
