I have pushed a version of these patches to a new branch lloda-array-support in Savannah.

If you would like to review them, please review them from there.

Thanks,

	Daniel

Now with a test. The first patch makes most of test-suite/tests/arrays.test run under both the compiler and the interpreter. It produces a large amount of errors under the compiler. The next two patches are the same as in the last email and fix these errors.

However, it's interesting to me that the errors in arrays.test somehow don't count as a failure in the final summary of the test suite. I believe this could be a bug in the test framework, but I'm not familiar with that code.

Regards,

	Daniel

Subject: [PATCH 1/3] Run some of arrays.test under both compiler &
 interpreter

* test-suite/test-suite/lib.scm (c&e): accept (pass-if exp) clause.

* test-suite/tests/arrays.test: use with-prefix/c&e instead of
  with-prefix where possible.

Fix the first patch to verify an assumption used in the new array SCM layout.

Subject: [PATCH 1/2] Pack array dimensions in array object

* libguile/arrays.c (scm_i_make_array): redo object layout.

* libguile/arrays.h (SCM_I_ARRAY_V, SCM_ARRAY_BASE, SCM_I_ARRAY_DIMS):
  to match new layout.

  (SCM_I_ARRAY_SET_V, SCM_ARRAY_SET_BASE): new setters.

  (SCM_I_ARRAY_MEM, scm_i_t_array): unused, remove.

  (scm_i_shap2ra, scm_make_typed_array, scm_from_contiguous_typed_array,
  scm_from_contiguous_array, scm_make_shared_array, scm_transpose_array,
  scm_array_contents): fix uses of SCM_I_ARRAY_V, SCM_ARRAY_BASE as
  lvalues.

* libguile/array-map.c (make1array, scm_ramapc): fix uses of
  SCM_I_ARRAY_V, SCM_ARRAY_BASE as lvalues.

[patch] literal arrays in master

[Daniel Llorens]

[-- Attachment #1: Type: text/plain, Size: 485 bytes --]


Hello,

these two patches fix the “don’t know how to intern” error in master when the compiler encounters a literal array (e.g. #2()) in the REPL.

All existing array tests pass, but the error didn't happen when loading files (e.g. if you load a file that has (define a #2()) somewhere, that was and remains fine). I don’t really understand the difference and I don’t know how to put a test for this patch in the test suite. Any advice is appreciated.

Regards

	Daniel

Subject: [PATCH 1/2] Pack array dimensions in array object

* libguile/arrays.c (scm_i_make_array): redo object layout.

* libguile/arrays.h (SCM_I_ARRAY_V, SCM_ARRAY_BASE, SCM_I_ARRAY_DIMS):
  to match new layout.

  (SCM_I_ARRAY_SET_V, SCM_ARRAY_SET_BASE): new setters.

  (SCM_I_ARRAY_MEM, scm_i_t_array): unused, remove.

  (scm_i_shap2ra, scm_make_typed_array, scm_from_contiguous_typed_array,
  scm_from_contiguous_array, scm_make_shared_array, scm_transpose_array,
  scm_array_contents): fix uses of SCM_I_ARRAY_V, SCM_ARRAY_BASE as
  lvalues.

* libguile/array-map.c (make1array, scm_ramapc): fix uses of
  SCM_I_ARRAY_V, SCM_ARRAY_BASE as lvalues.
