Shea Levy 997defa166 Add functors (callable attribute sets). 
With this, attribute sets with a `__functor` attribute can be applied
just like normal functions. This can be used to attach arbitrary
metadata to a function without callers needing to treat it specially.

Shea Levy 6062b12160 Fix build on gcc < 4.7 2014-10-20 12:15:50 -04:00
Shea Levy f040159f77 Revert "Drop support for pre-c++11 compilers." 
The breakage this fixed can be worked around without removing support.

This reverts commit 84a13dc576.

Eelco Dolstra ecc2c8f464 Improve printing of ASTs 2014-10-20 09:13:21 +02:00
Shea Levy 84a13dc576 Drop support for pre-c++11 compilers. 
In particular, gcc 4.6's std::exception::~exception has an exception
specification in c++0x mode, which requires us to use that deprecated
feature in nix (and led to breakage after some recent changes that were
valid c++11).

nix already uses several c++11 features and gcc 4.7 has been around for
over 2 years.

Eelco Dolstra 6bb4c0b712 mkList: Scrub better 
Clearing v.app.right was not enough, because the length field of a
list only takes 32 bits, so the most significant 32 bits of v.app.left
(a.k.a. v.thunk.env) would remain. This could cause Boehm GC to
interpret it as a valid pointer.

This change reduces maximum RSS for evaluating the ‘tested’ job in
nixos/release-small.nix from 1.33 GiB to 0.80 GiB, and runtime by
about 8%.

Eelco Dolstra b6809608cc Get rid of some unnecessary ExprConcatStrings nodes in dynamic attrs 
This gives a ~18% speedup in NixOS evaluation (after converting
most calls to hasAttr/getAttr to dynamic attrs).

Eelco Dolstra 53b044c2f6 Don't evaluate inside a "throw" 
Workaround for
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=41174. This caused

Eelco Dolstra 022618c794 Handle cycles when printing a value 
So this no longer crashes with a stack overflow:

  nix-instantiate -E --eval 'let as = { x = as; }; in as'

Instead it prints:

  { x = { x = <CYCLE>; }; }

consumption issues.
