Roland McGrath 92ae11d456 (__sigreturn): Arg is not const. ... After restoring SCP->sc_mask, check for pending signals (newly unblocked); if any, set SS->context to SCP, clear SS->intr_port, and send sig_post to the signal thread to deliver the pending signals. Don't write $1 value into the user stack. Instead, write it into the word just past SCP->sc_pc; then point $1 at SCP->sc_pc and use `op_sigreturn' pseudo-instruction to restore the PC and $1 from that.		1994-08-22 09:06:46 +00:00
