This flag was set, but never used in Guile, and there was no documented API to access it. To check if an array is contiguous, use (array-contents <> #t). * libguile/arrays.h (scm_i_raw_array): New function. SCM_I_ARRAY_CONTIGUOUS, SCM_SET_ARRAY_CONTIGUOUS_FLAG, SCM_CLR_ARRAY_CONTIGUOUS_FLAG, SCM_I_ARRAY_CONTP: Remove. scm_t_array_dim: Declare here, not in array-handle.h. SCM_I_ARRAY_NDIM: Shift by one bit since the contp flag isn't there anymore. * module/syste/vm/assembler.scm: Match removal of contp flag. * libguile/arrays.c (scm_i_make_array): Reuse scm_i_raw_array. (scm_i_ra_set_contp): Remove. (scm_transpose_array): Don't set or clear the contp flag. (scm_make_shared_array): Don't set or clear the contp flag. (scm_make_typed_array): Don't set the contp flag. * libguile/array-map.c (scm_i_array_rebase): Reuse scm_i_raw_array.
