e0aef0a575 fix two bugs in recent plai commit 2013-03-09 18:59:26 -06:00

38f5823a59 adjust plai's gc2 language to use roots as the arguments 
to gc:cons and gc:closure instead of passing locs

This enables the important change, namely that get-root-set
no longer returns roots corresponding to the arguments
of the allocation function that we're in the middle of.

This means that a common error students have (forgetting
to chase the 'hd' and 'tl' pointers in their GC) is
harder to make now, since get-root-set never contains
those locations as roots. (In the past you would have had
to write some pretty non-obvious mutator program to get
that behavior.)

ba3e676057 adjust the expansion of #%module-begin so it doesn't 
generate so much code

(Mostly to avoid pain with the macro stepper, but also
reducing the amount of code macros generates is good
for performance reasons)

3311387201 when anormalizing, never lift out identifiers from application expressions 
The code used to avoid lifting identifier in more restricted circumstances,
but it seems safe to alway avoid that, which can lead to a lot
less lifting

87f76e94f7 allow quote require forms in the argument to allocator-setup 
This is mostly to better support test cases so that we
can set up namespaces that have specific collectors in them
(easiest to do with quote-based requires)

b0ed3b49e0 adjust plai test & co. to print only failing tests to stderr, 
instead of printing all of them

also, adjust the plai test suites to cope with test results going
to two different places

727d11df83 adjust plai's test facility to print test failures to stderr 
instead of stdout (in addition to making errors red in drracket,
this will also make some of the existing test suites more
drdr friendly)

c42675f80c adjust gc2's mutator language: 
- give names to user functions that matches the user's names
    (if the third bullet goes away, then the function
     mutator-lift needs to be adjusted so that it uses
     procedure-rename in order to preserve the improvement
     in this bullet)

  - change exn? to exn:fail? (to avoid catching break exns)

  - change lang so that primitives (the ones in the
    provide-flat-prims/lift declaration) are not allocated
    in the user's space (treat them as if they are constants)

    This change makes it easier to build up and explain the
    GC api, piece by piece. That is, you can first run a program
    that contains just a constant (and explain it) with only a
    subset of the api. Then you can do something like (+ 1 2)
    and explain it, both without getting into how procedures work.

    (This is helpful for the way I run my lectures)

c2355caef6 Finalizing initial pass on GC2 
It was not a problem with the particular collector. All allocation
sites need to update the gc-roots-key with their static information.

collector. But I need to find out.
