      Fix a bug in the liveness analysis · 79791534
      Simon Marlow authored
      We were being overly conservative, registers that were live only at a
      branch target were not recorded as being dead in the branch-not-taken

      Use timer_create() for the interval timer, if available · e30aca19
      Simon Marlow authored
      This lets the threaded RTS use SIGVTALRM rather than SIGALRM for its
      interval timer signal, so the threaded and non-threaded RTS are
      compatible.  It unfortunately doesn't completely fix #850/#1156, for
      that we really have to use a restartable sleep instead of usleep().
      Also I cleaned up the timer API a little: instead of returning an
      error value that ultimately gets ignored, we now report errors from
      system calls and exit.

      Make let-matching work in Rules again · 5b51ce96
      simonpj@microsoft.com authored
      A RULE is supposed to match even if there is an intervening let:
      	RULE f (x:xs) = ....
      	target	   f (let x = thing in x:xs)
      It's surprisingly tricky to get this right; in effect we are doing
      let-floating on the fly. I managed to get it wrong before, or at least
      be over-conservative.  And in "fixing" that I got it wrong again in a
      different way, which made it far too conservative. In particular, it
      failed to match	f (let x = y+y in let z=x+y in z:xs)
      because the binder x was cloned and looked "locally-bound". See the
      ever growing comments with the Let rule for details.
      That patch reverts to the previous story, which is still a bit too 
      conservative, but not so egregiously so.  Fixes Romans's problem.
