allocateLocal which allocates from the given capability without
having to take any locks. In the gmp primops we're basically in
an unsafe foreign call, that is a context where we hold a current

need a way to get the current capability. The method to get the
current capability varies depends on whether we're using the
threaded rts or not. When stgAllocForGMP is built inside the rts

10 years agoAllow RULES for seq, and exploit them
simonpj@microsoft.com [Wed, 3 Jun 2009 09:29:56 +0000 (09:29 +0000)] 
Allow RULES for seq, and exploit them

Roman found situations where he had
      case (f n) of _ -> e
where he knew that f (which was strict in n) would terminate if n did.
Notice that the result of (f n) is discarded. So it makes sense to
transform to
      case n of _ -> e

Rather than attempt some general analysis to support this, I've added
enough support that you can do this using a rewrite rule:

  RULE "f/seq" forall n.  seq (f n) e = seq n e

You write that rule.  When GHC sees a case expression that discards
its result, it mentally transforms it to a call to 'seq' and looks for
a RULE.  (This is done in Simplify.rebuildCase.)  As usual, the
correctness of the rule is up to you.

This patch implements the extra stuff.  I have not documented it explicitly
in the user manual yet... let's see how useful it is first.

The patch looks bigger than it is, because
  a) Comments; see esp MkId Note [seqId magic]

  b) Some refactoring.  Notably, I moved the special desugaring for
     seq from MkCore back into DsUtils where it properly belongs.
     (It's really a desugaring thing, not a CoreSyn invariant.)

  c) Annoyingly, in a RULE left-hand side we need to be careful that
     the magical desugaring done in MkId Note [seqId magic] item (c)
     is *not* done on the LHS of a rule. Or rather, we arrange to
     un-do it, in DsBinds.decomposeRuleLhs.
