Guys,
1. remove [... _CURLWP_LABEL] arrangement in vm_machdep.c 2. remove S7 (T8) value restoration at the bottom of cpu_switchto().
I made changes and code was committed. Compiled Ok for pmax and disassembled binaries were inspected to verify the change. Should be no worse than previous state of -current. No test on real HW. Toru Nishimura / ALKYL Technology
