MERGE: Be less aggressive about the result discount Merge of: commit 4fa3f16ddb9fa8e5d59bde5354918a39e0430a74 Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Mon May 28 17:33:42 2012 +0100 Be less aggressive about the result discount This patch fixes Trac #6099 by reducing the result discount in CoreUnfold.conSize. See Note [Constructor size and result discount] in CoreUnfold. The existing version is definitely too aggressive. Simon M found it an "unambiguous win" but it is definitely what led to the bloat. In a function with a lot of case branches, all returning a constructor, the discount could grow arbitrarily large. I also had to increase the -funfolding-creation-threshold from 450 to 750, otherwise some functions that should inline simply never get an unfolding. (The massive result discount was allow the unfolding to appear before.) The nofib results are these, picking a handful of outliers to show.

Add defaultLogActionHPrintDoc to DynFlags We now use this function rather than Outputable.{printSDoc,printErrs}. Outputable is arguably a better home for the function, but putting it in DynFlags should dissuade people from using it inappropriately (in particular, nothing other than the default hooks should have stdout or stderr hardcoded). Not exporting it at all would also be an option, but exporting it with an ungainly name will make it slightly easier for people who want to send output to other Handles for some reason.

Change the `IP` class to avoid the ambiguity of the method. We use a phantom type to link an implicit parameter name to its value. This is nice because now `?x` in the source code is simply syntactic sugar for `ipUse (IPName :: "x")`, and we type check it in exactly that way. `ipDef` is used when we process implicit parameter bindings---it's only there to add the newtype constructor.

Fix problems with getMonotonicNSec on OS X We were incorrectly multiplying by 1e9, which (a) meant we were getting values that were far too large, and (b) meant that when we casted from double to StgWord64 the result was 0, as the value was out of range. We now do all the work as StgWord64.
