This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (1ef1cc72d9dabc3d06fec8de34f839b1e7d30532)
            \
             N -- N -- N (83341720d0f88aa3003325ece375b84797d10fca)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

commit 83341720d0f88aa3003325ece375b84797d10fca
Author: Daniel Llorens <address@hidden>
Date:   Wed May 8 16:06:40 2013 +0200

    array-contents returns root for empty arrays with empty root
    
    This fixes a compiler issue where (uniform-array->bytevector #2f64())
    failed because of the stricter definition of uniform-vector? on this branch.
    
    Perhaps it would be better if uniform-array->bytevector didn't require
    a contiguous argument.
    
    * libguile/arrays.c: (scm_array_contents): return the root regardless of
      the value of SCM_I_ARRAY_DIMS (ra)->inc.
    * test-suite/tests/arrays.test: check.

commit 15e70c68cfcda38d65b5bd55397b99b7b12703a7
Author: Daniel Llorens <address@hidden>
Date:   Thu May 2 11:43:31 2013 +0200

    Fix compilation bugs with some kinds of typed arrays
    
    * module/language/glil/compile-assembly.scm: pass (array-contents x)
      to uniform-array->bytevector instead of x, when x is a typed array.
    * test-suite/tests/arrays.test: test an instance of the above that
      failed in Guile 2.0.9.

commit c5bd3ae5186df5b75065cdfd594e27b3a29c2a1a
Author: Daniel Llorens <address@hidden>
Date:   Tue Apr 30 16:11:07 2013 +0200

    Preallocate index list in scm_array_index_map_x
    
    * libguile/array-map.c
      - (scm_array_index_map_x): preallocate the index list instead of
        constructing it on each rank-1 iteration.
      - (ramap, rafe): use SCM_I_ARRAY_V just once.

commit 4edff3e1b5952b89a897e4ff57f8eba66d45b511
Author: Daniel Llorens <address@hidden>
Date:   Mon Apr 29 14:19:52 2013 +0200

    Match types used in arrays.c to struct field types
    
    * libguile/arrays.c
      - scm_shared_array_root: check for SCM_I_ARRAYP first.
      - scm_i_shap2ra:
        * check valid bounds in the '(lbnd ubnd) case. This makes
          (make-array 0 '(4 -3)) fail with a 'bad dimension' instead of
          with a 'wrong index' error.
        * use ssize_t for lbnd/ubnd/inc, not long.
      - scm_make_shared_array: use ssize_t for indices, not long.
      - scm_transpose_array: use size_t for ndim, not ulong.
      - scm_i_print_array: idem.

Date:   Fri Apr 26 13:02:38 2013 +0200

    Don't use ASET in scm_array_index_map_x
    
    * libguile/array-map.c: (scm_array_index_map_x): replace ASET by direct
      use of handle->impl.

commit c24c98d080c0c67836d28fbf6b7422e5fd59af3f
Author: Daniel Llorens <address@hidden>
Date:   Fri Apr 26 02:05:22 2013 +0200

    In scm_ramapc, only check unrolled axes for emptiness
    
    * libguile/array-map.c: (scm_ramapc)
      - Don't check emptiness while preparing ra0, but only after kroll is 
known,
        and only before kroll. len = 0 will be caught by the unrolled loop.
      - Use ra0 axis length in unroll check depth for rest args, not ra1's.
      - Recover early exit feature when cproc returns 0.

Author: Daniel Llorens <address@hidden>
Date:   Thu Apr 25 18:49:14 2013 +0200

    Fix scm_ramapc bugs with 0-inc arrays
    
    * libguile/array-map.c: (scm_ramapc): Cannot flag empty on the product
      inc * dim * dim ... Check every dim.
    * test-suite/tests/ramap.test: Tests the 0-inc, non empty case for both
      array-map! and array-copy!.

Author: Daniel Llorens <address@hidden>
Date:   Thu Apr 25 15:18:05 2013 +0200

    Fix corner cases of scm_ramapc
    
    * libguile/array-map.c
      - (scm_ramapc): mismatched axes limit unrollk (kroll). Reorganize
        the function to do all checking as we go.
      - (scm_ra_matchp): unused; remove.
      - (find_unrollk): inlined in scm_ramapc; remove.
      - (klen): inlined in scm_ramapc; remove.
      - (rafill): n is size_t.
      - (racp): n is size_t. Use n and not i0end to bound the loop.
      - (ramap): Use n and not i0end to bound the loop. This is needed for the 
rank
        0 case to work with the new scm_ramapc, as inc may be set to 0 in that 
case.
      - (rafe): idem.
    * test-suite/tests/ramap.test
      - check that size mismatch prevents unrolling (matching behavior III) with
        both array-copy! and array-map!.
      - check that non-contiguous stride in non-ref args prevents unrolling
        (rank 2, discontinuous) with both array-copy! and array-map!.
      - check rank 0 cases with array-for-each, array-map!.

    Rewrite scm_ramapc()
    
    * libguile/array-map.c
      - (cind): replace by cindk, that operates only on the unrolled index set.
      - (klen): new function.
      - (make1array): take extra inc argument.
      - (scm_ramapc): rewrite to unroll as many axes as possible instead of 
just all
        or one.
      - (AREF): lbnd is known to be 0: remove.
      - (ASET): v is known to come from SCM_I_ARRAY_V; assume base, inc, lbnd.
      - (racp): use ssize_t instead of long for the indices.
      - (scm_array_index_map_x): build the index list at the last-but-one axis, 
then
        set the car of the last element, instead of building the list at the 
last axis.
    * test-suite/tests/ramap.test
      - add array-map! test with offset arguments.

    Factor out make1array() in scm_ramapc()
    
    * libguile/array-map.c: (scm_ramapc): factor out vector->array conversion
      to aux function make1array.
