Run "make update-copyright", but then also run this,
perl -pi -e 's/2\d\d\d-//' tests/sample-test
to make that one script use the single most recent year number.

This follows suggestions by Jim Meyering in
<http://bugs.gnu.org/12841#34>.
* src/make-prime-list.c (print_wide_uint): Change "nested" argument
to "nesting", and use it to avoid outputting lines that are too long.
* src/primes.h: Remove from git. This can be generated by a
maintainer. It's nicer to do so on a host with at least 128-bit
arithmetic.
|

With this change, the maintainer builds primes.h and it is part of
the tarball. primes.h's contents are not architecture-specific.
* .gitignore: Remove /src/primes.h.
* src/factor.c: Include verify.h.
(W): New constant. Verify that uintmax_t lacks holes
and that W is no wider than the integers used to generate primes.h.
* src/local.mk (EXTRA_DIST): Add src/primes.h.
(BUILT_SOURCES, CLEANFILES): Remove src/primes.h.
($(top_srcdir)/src/primes.h): Rename from src/primes.h.
Do not depend on src/make-prime-list. Instead, use sub-make to
build, so that we build primes.h only if it does not exist.
* src/make-prime-list.c: Include <limits.h>, for ULONG_MAX.
(wide_uint): Define to uintmax_t or unsigned __int128 if not #defined.
(struct prime, binvert, process_prime): Use it instead of uintmax_t.
(print_wide_uint): New function. This generates the proper pinv
value regardless of the width of uintmax_t on the target, so long
as the width doesn't exceed that of the width of wide_uint on the
maintainer host that generated src/primes.h.
(output_primes): Use it. Output WIDE_UINT_BITS, too. Let the
target compute its own lim, since its uintmax_t may be narrower
than ours.
(SZ): Remove.
* src/primes.h: New file, generated with 128-bit integers and usable
on any host where uintmax_t's width is no greater than 128 bits.
|
|
* src/make-prime-list.c (malloc): Undef. This fixes a problem on
AIX 8.20 reported by Michael Felt in <http://bugs.gnu.org/12841>.

This was not seen to be an issue in practise,
but to make the code more robust, don't assume
uintmax_t is 64 bits.
* src/factor.c (W_TYPE_SIZE): Define based on integer limits.
* src/make-prime-list.c (output_primes): Define format width
based on integer limits.
|
|
* src/make-prime-list.c: Hardcode the uintmax_t width
to 16 hex digits (64 bit), to avoid this compile issue
on HPUS systems at least.

When building the new make-prime-list program on a system for which
strerror is defined to rpl_strerror, we'd get a link failure.
The problem is that we're including <config.h> for some definitions,
but do not want the rpl_ ones, since this particular program must
not be linked against gnulib (aka libcoreutils.a). This did not
arise on Fedora 17 or 18, but did on Debian wheezy/sid.
* src/make-prime-list.c (strerror): #undef.
Build failure introduced by commit v8.19-152-gcf67e4c.
|
|
* src/make-prime-list.c: Insert spaces before parens.
(main): Abort if the 8-delta value ever exceeds 255.

Even though this is just a helper program that is run solely to create
primes.h, it should not ignore a write failure. Normally we would
simply call atexit (close_stdout), but we cannot do that from this
helper program, since it must be built before the generated header,
primes.h. If we were to make the linking of make-prime-list depend
on libcoreutils.a, that would add all lib/*.o files to the list
of dependents of $(BUILT_HEADERS). Then, since there is currently no
provision to ensure that a file like lib/stdio.h (another built header)
is built before the first lib/*.o file that also includes <stdio.h>,
some lib/*.o files would be built before lib/stdio.h and some after.
The former would provoke link failures due to undefined rpl_* functions.
* src/make-prime-list.c: Include <errno.h>.
(fclose): Undef, so that a definition to rpl_fclose does not
cause a link failure.
(main): Per the above, in this exceptional case, we check for fclose
and ferror failure manually, and don't worry about the ferror-only
failure case in which errno may not be relevant.
|
|
* src/make-prime-list.c: Include <config.h>.
(binvert): Add _GL_ATTRIBUTE_CONST.
|
|
* src/make-prime-list.c: New file, from nt-factor.
