This change properly saves the pointer before doing the syscall and stores the return value in the pointer on return. This makes sigpending regress pass. The assembly for sigprocmask(2) had a tiny typo which made it jump to 2017-02-22T22:18:51Z patrick patrick@openbsd.org 2017-02-22T22:18:51Z urn:sha1:fc53081f2fd93c822275cae847d9aaefbe874af3 the wrong location, thus not making it set SIG_BLOCK with a zero mask when attempting to read the signal mask (if set ptr is NULL). Instead an attempt to read the mask actually told the syscall to set the mask to zero. __tfork(3) returns the thread ID of the new thread in x0, not x1.
