hu_HU: change time separator to colon [BZ #18918]
The previous (11th) version of the Hungarian spelling rules (released
in 1984) said that the separator had to be a dot, e.g. 10.35 meaning
10 o'clock 35 minutes. glibc correctly implements this.
The brand new (12th) version, in effect since September 1, 2015 adopts
to the common use of colon (especially in the digital world) and
allows to use either separator, without even expressing a preference.
For computer systems, using colons is way more typical and probably
easier to recognize. Dot is typically used in printed materials.
It also avoids an almost ambiguous situation where a space makes a
difference, e.g. "10.15-ig" means "until 10 o'clock 15 minutes"
whereas "10. 15-ig" means "until 15th of October". So I believe using
the colon as the separator is not only more frequent in the computer
world, but is also easier and quicker to recognize for the brain that
it's about hour:minute rather than month and day. And luckily it's now
equally correct according to the official rules.
11th edition: http://helyesiras.mta.hu/helyesiras/default/akh11
12th edition: http://helyesiras.mta.hu/helyesiras/default/akh12
In both editions it's the very last (299th and 300th, respectively) rule.
Microsoft also uses and recommends a colon since at least May 2011:

The time format is different in common language and in the language of
IT. In common texts we usually do not abbreviate, so the full forms are
used: “7 óra 10 perckor csörgött a telefon”. However, the short format,
consisting of numerals only, can also be used. In this case a period
must be used between the two numbers and there must not be a space
between them: “találkozzunk 10.45-kor”.
However, in software mostly the short format is used, and the numbers
are separated by a colon. An obvious example is the clock in the bottom
right corner of your screen, thus 18:31.

Convert 703 function definitions to prototype style.
This automatically-generated patch converts 703 function definitions
in glibc from old-style K&R to prototype-style.
This conversion is deliberately simplistic, excluding any tricky cases
as even a patch covering only simple cases is still very large.
Currently excluded are: sysdeps files (to improve test coverage for
the initial patch); files containing assertions (to avoid line number
changes so that generated libraries can be compared); any cases where
the generated function declaration would involve lines over 79
characters and so need to be wrapped; any cases with array parameters
or other cases where parameter declarators don't end with the
parameter name; any other cases that my script didn't parse.
I didn't try to make the ChangeLog generation indicate when function
definitions are conditional; it just lists the functions changed
without regard to that.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

Remove NPTL configure errors based on top-level configure tests.
sysdeps/nptl/configure.ac has code to give errors if certain tests in
the top-level configure failed. However, all those failure conditions
also produce errors in the top-level configure, so the errors in the
NPTL configure are completely redundant; this patch removes them.
(As suggested in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00510.html>, I think
the top-level tests in question can be completely removed as
unnecessary given the version tests. But even without that there is
clearly no point in duplicating code that gives an error if the test
fails.)

Do not leave files behind in /tmp from testing.
I noticed that glibc testsuite runs left several files behind in /tmp
(or TMPDIR, if different). The problem was testcases that generate a
template for mkstemp / mkstemp64, ending with XXXXXX, then pass that
template to add_temp_file before calling mkstemp / mkstemp64, meaning
that the template ending with XXXXXX is stored in the list of
temporary files to delete (add_temp_file uses strdup so that the
original string doesn't need to stay live), not the actual filename as
determined by mkstemp / mkstemp64. This patch fixes those tests to
call add_temp_file later.
Tested for x86_64 (that the files are no longer left behind by a
testsuite run and the modified tests still pass).

Fix powerpc32 lround, lroundf spurious exceptions (bug 19134).
The powerpc32 implementation of lround and lroundf can produce
spurious exceptions from adding 0.5 then converting to integer. This
includes "inexact" from the conversion to integer (not allowed for
integer arguments to these functions), and, for larger integer
arguments, "inexact", and "overflow" when rounding upward, from the
addition. In addition, "inexact" is not allowed together with
"invalid" and so inexact addition must be avoided when the integer
will be out of range of 32-bit long, whether or not the argument is an
integer.
This patch fixes these problems. As in the powerpc64 llround
implementation, a check is added for too-large arguments; in the
powerpc64 case that means arguments at least 2^52 in magnitude (so
that 0.5 cannot be added exactly), while in this case it means
arguments for which the result would overflow "long". In those cases
a suitable overflowing value is used for the integer conversion
without adding 0.5, while for smaller arguments it's tested whether
the argument is an integer (by adding and subtracting 2^52 to the
absolute value and comparing with the original absolute value) to
avoid adding 0.5 to integers and generating spurious "inexact".
This code is not used when the power5+ sysdeps directories are used,
as there's a separate power5+ version of these functions..
Tested for powerpc. This gets test-float (for a default powerpc32
hard-float build without any --with-cpu) back to the point where it
should pass once powerpc ulps are regenerated; test-double still needs
another problem with exceptions fixed to get back to that point (and I
haven't looked lately at what default powerpc64 results are like).

Fix powerpc32 llround, llroundf exceptions (bug 19125).
The powerpc32 implementations of llroundf and llround produce spurious
and missing exceptions (some arising from such exceptions from
conversions to long long, some present even when fctidz is used).
This patch fixes those problems in a similar way to the llrint /
llrintf fixes. The spurious exceptions in the fctidz case for large
arguments arise from a converted value that saturated as LLONG_MAX
being converted back to float or double (the conversion back being
inexact, but "inexact" must not be raised together with "invalid"),
and from the subtraction x - xrf also being inexact for sufficiently
large arguments (whether the saturation was to LLONG_MAX or
LLONG_MIN); those are fixed by returning early if the argument is
large enough that no rounding is needed.
This code is not used for --with-cpu=power4 builds (I suspect the code
used in that case may also produce spurious "inexact" exceptions, but
that's something to investigate later).

Fix dbl-64 lrint for 64-bit long (bug 19095).
The dbl-64 implementation of lrint produces incorrect results for some
arguments with 64-bit long because a 32-bit (unsigned) low part of the
mantissa is shifted left, losing high bits in the process. This patch
fixes this by casting to long int before shifting, as in lround (as
this case only applies for 64-bit long, there are no issues with
sign-extension).

Fix lrint, llrint missing exceptions close to overflow threshold (bug 19094).
The dbl-64, ldbl-96 and ldbl-128 implementations of lrint and llrint
fail to produce "invalid" exceptions in cases where the rounded result
overflows the target type, but truncating the floating-point argument
to the next integer towards zero does not overflow it (so in
particular casts do not produce such exceptions). (This issue cannot
arise for float, or for double with 64-bit target type, or for ldbl-96
with 64-bit target type and negative arguments, because of
insufficient precision in the floating-point type for arguments with
the relevant property to exist. It also obviously cannot arise in
FE_TOWARDZERO mode.)
This patch fixes these problems by inserting checks for the special
cases that can occur in each implementation, and explicitly raising
FE_INVALID (and avoiding the cast if it might raise spurious
FE_INEXACT, while raising FE_INEXACT explicitly in the cases where it
is needed; unlike lround and llround, FE_INEXACT is required, not
optional, for these functions for a within-range inexact result).
The fixes are conditional on FE_INVALID or FE_INEXACT being defined.
If any future architecture supports one but not both of those
exceptions, the code will fail to compile and need fixing to handle
that case (this seemed better than conditioning on both macros being
defined, resulting in code that would compile but quietly miss
exceptions on such a system).
Tested for x86_64, x86 and mips64. Tested the ldbl-96 changes (only
relevant for ia64, it appears) on x86_64 by removing the x86_64

strcoll: Remove incorrect STRDIFF-based optimization (Bug 18589).
The optimization introduced in commit
f13c2a8dff2329c6692a80176262ceaaf8a6f74e, causes regressions in
sorting for languages that have digraphs that change sort order, like
cs_CZ which sorts ch between h and i.
My analysis shows the fast-forwarding optimization in STRCOLL advances
through a digraph while possibly stopping in the middle which results
in a subsequent skipping of the digraph and incorrect sorting. The
optimization is incorrect as implemented and because of that I'm
removing it for 2.23, and I will also commit this fix for 2.22 where
it was originally introduced.
This patch reverts the optimization, introduces a new bug-strcoll2.c

ensures they sort one digraph each correctly. The optimization can't be
applied without regressing this test.

malloc: Consistently apply trim_threshold to all heaps (Bug 17195)
In the per-thread arenas we apply trim_threshold-based checks
to the extra space between the pad and the top_area. This isn't
quite accurate and instead we should be harmonizing with the way
in which trim_treshold is applied everywhere else like sysrtim
and _int_free. The trimming check should be based on the size of
the top chunk and only the size of the top chunk. The following
patch harmonizes the trimming and make it consistent for the main
arena and thread arenas.
In the old code a large padding request might have meant that
trimming was not triggered. Now trimming is considered first based
on the chunk, then the pad is subtracted, and the remainder trimmed.
This is how all the other trimmings operate. I didn't measure the
performance difference of this change because it corrects what I
consider to be a behavioural anomaly. We'll need some profile driven
optimization to make this code better, and even there Ondrej and
others have better ideas on how to speedup malloc.

Fix ldbl-128ibm log1pl (-1) sign of infinity (bug 19076).
The ldbl-128ibm implementation of log1pl produces an infinity with the
wrong sign for log1pl (-1) in FE_DOWNWARD mode. This patch fixes this
by changing a division (-1.0L / (x - x)) (incorrect in FE_DOWNWARD
mode) to (-1.0L / 0.0L) (correct in all rounding modes).
Tested for powerpc.
[BZ #19076]
* sysdeps/ieee754/ldbl-128ibm/s_log1pl.c (__log1pl): Divide by
constant 0.0L when computing infinite result.

nss_nis: Do not call malloc_usable_size [BZ #10432]
This is a namespace violation, and interposed malloc implementations
are not required to interpose malloc_usable_size.
