Philippe suggested that I run the TCG tests for Hexagon. Thanks Philippe!!
I discovered that I'm not handling SIGSEGV properly. We pass other signal tests, but not this one. I'm hoping someone can help. The first thing that I realized is that I hadn't provided a tlb_fill function for CPUClass. What is this function supposed to do? I looked at other targets and found they are setting cs->exception_index to something and then call cpu_loop_exit_restore. I tried various values for exception_index, but the best I seem to get is re-executing the offending instruction forever. Any insight would be greatly appreciated. Thanks, Taylor PS The only other bug that these tests uncovered was that truncate isn't implemented properly. This was straightforward to fix.
