      Optimise whole module exports · 4b72f859
      Matthew Pickering authored 
      We directly build up the correct AvailInfos rather than generating
lots of singleton instances and combining them with expensive calls to
unionLists.

There are two other small changes.

* Pushed the nubAvails call into the explicit export list
  branch as we construct them correctly and uniquely ourselves.
* fix_faminst only needs to check the first element of the export
  list as we maintain the (yucky) invariant that the parent is the
  first thing in it.

      Add missing SMP symbols to RT linker. · 94d1221c
      Tamar Christina authored 
      Summary:
Add some missing symbols that we
export from the public headers but forgot to include
in the runtime linker's symbol table.

This is a bit of a unsatifactory patch, since we have a bit of a
cat and mouse game going. We should find a way to automate this.

But I know of no good solutions at the moment that won't add all
rts symbols (including those we don't have an extern declaration for.).

So for now, just add the ones reported missing.

      It seems like GCC versions prior to 4.8 exit with code 0 when faced with
an unrecognized flag. Silly compilers.

      Fix numa001 failure with "too many NUMA nodes" · e0ca7ff3
      Simon Marlow authored 
      It seems that recent versions of the Linux kernel are using larger NUMA
bitmasks; I see 1024 on my laptop running a 4.6.5 kernel.  This causes
the NUMA tests to fail.  I'm fixing it to only fail if we have that many
actual *nodes*, rather than failing if the size of the mask is too big.

      Accept output for scc003 · 034e01e4
      Simon Marlow authored 
      Looks like e3f341f3 broke it, but we
wouldn't have noticed because the test isn't run in validate.

I think the change is OK.  We don't get a tick for x' any more, because
it is converted directly to a case instead of a let-binding, but we
still get a tick for the "pattern binding" (!x').  This could be better
- f.(...) isn't all that intuitive - but it's not strictly wrong.

      Remove CONSTR_STATIC · 55d535da
      Simon Marlow authored 
      Summary:
We currently have two info tables for a constructor

* XXX_con_info: the info table for a heap-resident instance of the
  constructor, It has type CONSTR, or one of the specialised types like
  CONSTR_1_0

* XXX_static_info: the info table for a static instance of this
  constructor, which has type CONSTR_STATIC or CONSTR_STATIC_NOCAF.

I'm getting rid of the latter, and using the `con_info` info table for
both static and dynamic constructors.  For rationale and more details
see Note [static constructors] in SMRep.hs.

I also removed these macros: `isSTATIC()`, `ip_STATIC()`,
`closure_STATIC()`, since they relied on the CONSTR/CONSTR_STATIC
distinction, and anyway HEAP_ALLOCED() does the same job.

      Kill Type pretty-printer · 6c0f10fa
      Ben Gamari authored and Ben Gamari's avatar Ben Gamari committed 
      Here we consolidate the pretty-printing logic for types in IfaceType. We
need IfaceType regardless and the printer for Type can be implemented in
terms of that for IfaceType. See #11660.

Note that this is very much a work-in-progress. Namely I still have yet
to ponder how to ease the hs-boot file situation, still need to rip out
more dead code, need to move some of the special cases for, e.g., `*` to
the IfaceType printer, and need to get it to validate. That being said,
it comes close to validating as-is.
