[Qemu-devel] [PATCH 00/10, v3] target-alpha improvements

[Richard Henderson <rth@twiddle.net>]

Changes from v1->v2:
  * Use setcond and goto_tb.

Changes from v2->v3:
  * Enable NPTL.

I don't see how any sort of emulation of cmpxchg/load-locked is working
for any currently enabled nptl target.  I think how I've approached
handling load-locked for alpha is probably the easiest way.  Slightly
better would be if TCG had a (set of) cmpxchg opcodes, which would have
the benefit of getting the virt->phys->host address (and segfault handling)
more correct.  I've sort of totally ignored the faulting for now.

This is just good enough to not immediately fail the glibc testsuite for
alpha, as the default glibc test skeleton uses clone.  I'm concurrently
debuging the glibc-alpha port and the qemu-alpha syscall emulation, so
it's not always clear which is at fault.
