15 years agoAdd the notion of "constructor-like" Ids for rule-matching
simonpj@microsoft.com [Wed, 18 Mar 2009 10:59:11 +0000 (10:59 +0000)]
Add the notion of "constructor-like" Ids for rule-matching

This patch adds an optional CONLIKE modifier to INLINE/NOINLINE pragmas,
   {-# NOINLINE CONLIKE [1] f #-}
The effect is to allow applications of 'f' to be expanded in a potential
rule match.  Example
  {-# RULE "r/f" forall v. r (f v) = f (v+1) #-}

Consider the term
     let x = f v in ..x...x...(r x)...
Normally the (r x) would not match the rule, because GHC would be scared
about duplicating the redex (f v). However the CONLIKE modifier says to
treat 'f' like a constructor in this situation, and "look through" the
unfolding for x.  So (r x) fires, yielding (f (v+1)).

The main changes are:
  - Syntax

  - The inlinePragInfo field of an IdInfo has a RuleMatchInfo
    component, which records whether or not the Id is CONLIKE.
    Of course, this needs to be serialised in interface files too.

  - The occurrence analyser (OccAnal) and simplifier (Simplify) treat
    CONLIKE thing like constructors, by ANF-ing them

  - New function coreUtils.exprIsExpandable is like exprIsCheap, but
    additionally spots applications of CONLIKE functions

  - A CoreUnfolding has a field that caches exprIsExpandable

  - The rule matcher consults this field.  See
    Note [Expanding variables] in Rules.lhs.

On the way I fixed a lurking variable bug in the way variables are
expanded.  See Note [Do not expand locally-bound variables] in
Rule.lhs.  I also did a bit of reformatting and refactoring in
Rules.lhs, so the module has more lines changed than are really
different.

Add fast event logging

Generate binary log files from the RTS containing a log of runtime
events with timestamps.  The log file can be visualised in various
ways, for investigating runtime behaviour and debugging performance
problems.  See for example the forthcoming ThreadScope viewer.

New GHC option:

  -eventlog   (link-time option) Enables event logging.

  +RTS -l     (runtime option) Generates <prog>.eventlog with
              the binary event information.

This replaces some of the tracing machinery we already had in the RTS:
e.g. +RTS -vg  for GC tracing (we should do this using the new event
logging instead).

Event logging has almost no runtime cost when it isn't enabled, though
in the future we might add more fine-grained events and this might
change; hence having a link-time option and compiling a separate
version of the RTS for event logging.  There's a small runtime cost
for enabling event-logging, for most programs it shouldn't make much
difference.

something more automatic before releasing this).

To get the "PARGC3" configuration described in the "Runtime support

The main advantage of this is that it allows us to easily disable
load-balancing altogether, which turns out to be important in parallel

spreading the work out in parallel GC.  There is a side benefit in

Rewrite of signal-handling (ghc patch; see also base and unix patches)

The API is the same (for now).  The new implementation has the
capability to define signal handlers that have access to the siginfo
of the signal (#592), but this functionality is not exposed in this
patch.

#2451 is the ticket for the new API.

The main purpose of bringing this in now is to fix race conditions in
the old signal handling code (#2858).  Later we can enable the new
API in the HEAD.

Implementation differences:

 - More of the signal-handling is moved into Haskell.  We store the
   table of signal handlers in an MVar, rather than having a table of
   StablePtrs in the RTS.

 - In the threaded RTS, the siginfo of the signal is passed down the
   pipe to the IO manager thread, which manages the business of
   starting up new signal handler threads.  In the non-threaded RTS,
   the siginfo of caught signals is stored in the RTS, and the
   scheduler starts new signal handler threads.
