* src/longlong.h: Sync with the latest longlong.h from libgmp to:
- Use __builtin_c[lt]zl on arm64.
- Fix sparc64 vis3 build failure due to missing __clz_tab.
- Avoid a clang build issue on mips.
- Support thumb2 arm 32 bit system.
* src/cfg.mk (sc_ensure_comma_after_id_est): Exclude longlong.h
to ease merges.
|

To align with all other places (and correct grammar), change all
upper-case "I.E." to "I.e.". Furthermore, ensure that "i.e." is
followed by a comma. Finally, ensure to use a double-space before
"I.e.," at the beginning of a sentence.
The following was used to change all offending uses (apart from
old ChangeLog files):
$ git grep -liF 'i.e.' \
| xargs sed -i \
-e 's/I\.E\./I.e./g' \
-e 's/\. \(I\.e\.\)/. \1/g' \
-e 's/\([Ii]\.e\.\)\( \)/\1,\2/g' \
-e 's/\([Ii]\.e\.\)$/\1,/g'

Run "make update-copyright" and then...
* tests/sample-test: Adjust to use the single most recent year.
* tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message,
so that year is updated automatically in future.
|
|
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.

* src/longlong.h: Sync with the latest longlong.h from libgmp to:
- avoid arm asm when being compiled for the thumb instruction [sub]set
- avoid old powerpc assembly that is incompatible with newer GCC
- add arm64 optimized count_trailing_zeros()
- add sparc64 optimized add_ssaaaa() and umul_ppmm()
|
|
* src/longlong.h (__aarch64__): Make add_ssaaaa and sub_ddmmss work.
* NEWS: Mention the build fix.

In addition to the previous 64 bit guards we've placed in longlong.h
there are additional _LP64 guards required for mips with -mcpu >= 3,
to avoid a build failure (http://bugs.gnu.org/13353) and on sparc
with -mcpu >= v9 in 32 bit mode where for example,
`factor 2123123123123123123123` would go into an infinite loop.
Since factor.c currently operates on uintmax_t, we restrict the use
of the assembly in longlong.h to when 'long' has the same width, to
provide a more general guard for this code.
* src/factor.c: Restrict the use of longlong.h assembly code,
to when the width of intmax_t == long.
* src/longlong.h: Remove the previous _LP64 guards to avoid
divergence from GMP's longlong.h
* NEWS: Adjust the info on build and runtime fixes.

The current x86_64 asm code does not work for x32 (__ILP32__) ABIs,
so disable it. Note simply deleting the q suffix is not enough.
* src/longlong.h: Restrict x86_64 assembly to _LP64 targets,
which is consistent with other checks in longlong.h and
avoids this code on x32.
* NEWS: Mention the build fix.

Both Debian and Ubuntu builds of coreutils 8.20 hang while running the
test suite on powerpc, which is reproducible using 'factor 122'.
This turns out to be somewhat related to http://bugs.gnu.org/12754,
but not quite the same. uintmax_t is 64 bits, but the cntlzw
instruction takes 32-bit operands, and the cntlzd option is only
available on 64-bit hardware.
* src/longlong.h: Add an _LP64 check around the PPC64 code,
so that this falls back to the C implementations.
* NEWS: Mention the fix.
|
|
* src/longlong.h: Restrict some HPPA assembly variants to PA RISC V2.0.
Note we also avoid this assembly for ilp32 runtimes, since even though
the assembly is accepted there, it's not safe as the context can get
clobbered between the 'add' and 'add,dc'.
This fixes a compile failure with newer HPPA systems with default
GCC CPU options.

|
* src/factor.c: Renamed from factor-ng.c, with the following changes:
Adjust copyright header to be consistent with others.

s/fprintf+exit/error/
(print_factors): Add comments.
(strto2uintmax): Return strtol_error, not int.
