ACK. Just one more note to the wider audience. I looked at QEMU's user mode support for nios2 on/off over the last couple years. It never seemed to work well enough be able to run the GCC testsuite reliably. As a result, my tester builds nios2 and will run the testsuite, but all the execution tests are only built, they're not actually run. It's been fairly stable, but its not doing in-depth testing. jeff
