1. Which ones? I know that Windows uses it for the "this" pointer. Anyway, unless the callee is required to preserve it in a given calling convention, that doesn't preclude us using it for a *return* value. It would be checked after calls return, and wouldn't affect the use of the register for passing values in before the call is made. The callee would set it right before

...read/write one pointer to a single thread-local global variable. The next step would be to replace the mysetjmp call with a new intrinsic, and then I'd have to save EIP and do an indirect jump to it at the unwind site instead of jumping to a constant offset within the native mysetjmp. Making mylongjmp call a new intrinsic will necessitate no other modifications.
