* module/ice-9/psyntax.scm: Use the newer LGPLv3 header. Add FSF
copyright lines for each year the file was modified. Remove inline
changelogs. Remove some comments describing psyntax in other Scheme
implementations.
This way you can directly iterate blocks of a certain kind. Also verify
these lists more thoroughly, and allow full blocks that are the results
of evacuation to skip being swept the next round. Also! Have
next_hole_in_block / next_hole_in_block ensure that the object data and
the mark bytes are clear.
* module/language/cps/intset.scm (make-intset-folder): intset-fold-right
on a transient intset would dispatch to left fold after making the
persistent set. Sadness!
* doc/ref/api-data.texi (Arrays as arrays of arrays): Clarify
ambiguities, fix examples.
* libguile/arrays.c (make-shared-array): Make error messages specific to
each error case, report relevant arguments.
(array_from_pos): Return NULL on error instead of reporting error
ourselves.
(array_from_get_o): Handle the trivial case.
(scm_array_slice, scm_array_cell_ref, scm_array_cell_set_x): Don't
build error arguments before error happens. Let array_from_get_o
handle the trivial case.
Prepare for fixes to the suffix pruning. Since last_component doesn't
document a possible null result in lib/basename-lgpl.h, and the current
code also doesn't appear capable of producing one, drop the check.
libguile/filesys.c (basename): drop check for last_component null result.
Rewrite the srfi-1 C functions in Scheme and remove srfi-1.c as
planned (see the comments at the top of srfi-1.c).
The previous C code mutated intermediate results in some cases, even for
non-! functions (e.g. set-cdr! to build the result without stack growth
or a reverse!); some of the conversions preserve that approach for now.
Simple testing via https://github.com/ecraven/r7rs-benchmarks/ didn't
reveal any substantial performance regressions.
Thanks to David Thompson for reviewing the changes and suggesting
improvements.
...now that all of the C code has been migrated to Scheme.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
remove srfi-1.c.
(DOC_X_FILES): Remove srfi-1.x.
(DOT_DOC_FILES): Remove srfi-1.doc.
(modinclude_HEADERS): Remove srfi-1.h.
* libguile/init.c (scm_i_init_guile): Don't call scm_register_srfi_1.
* libguile/srfi-1.c: Remove.
* libguile/srfi-1.h: Remove.
* module/srfi/srfi-1.scm: Don't load srfi-1 from libguile.
