A ton of kernel code is still needed, currently I'm trying to get exceptions working properly (the NetBSD code leaves a bit to be desired and doesn't work right @64-bits). Also I am seeing a lot of unexpected access (deterministic) to bogus bits of memory, possibly as a result of stack corruption, or a stack size issue, I'm not sure. Using random printfs seems to make these things better/worse non-deterministically, but a printf in a given location deterministically changes how things work. This may be evidence of a compiler bug, but I'm not sure. Certainly there are bugs in the compiler. With -O the compiler ICEs, I seem to recall. imp@ suggests maybe it's a cache issue, but I've tried with L1 cache disabled, with the kernel running in KSEG1, and so on, to no avail. Thanx, juli. -- juli mallett. email: jmallett@freebsd.org; efnet: juli;
