Fix implicit __isinf declarations in exp.

Fix dbl-64 exp overflow/underflow in non-default rounding modes (bug 16284).
The dbl-64 version of exp needs round-to-nearest mode for its internal
computations, but that has the consequence of inappropriate
overflowing and underflowing results in other rounding modes. This
patch fixes this by recomputing the relevant results in cases where
the round-to-nearest result overflows to infinity or underflows to
zero (most of the diffs are actually just consequent reindentation).
Tests are enabled in all rounding modes for complex functions using
exp - but not for cexp because it turns out there are bugs causing
spurious underflows for cexp for some tests, which will need to be
fixed separately (I suspect ccos ccosh csin csinh ctan ctanh have
similar bugs, just not shown by the present set of test inputs).

Fix -Wundef warnings for _ABI* on MIPS.
This patch fixes -Wundef warnings related to the _ABI* macros on MIPS.
GCC predefines only the _ABI* macro related to the ABI actually in

true only for the ABI in question (all the macros are nonzero), but
produces a -Wundef warning for the other ABIs. The normal approach to
using these macros is to include <sgidefs.h>, which ensures that all

Fix log (1) in round-downward mode (bug 16731).
According to ISO C Annex F, log (1) should be +0 in all rounding
modes, but some implementations in glibc wrongly return -0 in
round-downward mode (mapping to log1p (x - 1) is problematic because 1
- 1 is -0 in round-downward mode, and log1p (-0) is -0). This patch
fixes this. (It helps with some implementations of other functions

enable all-rounding-modes testing for those functions without further
fixes to other implementations of them.)

Test most libm functions in all rounding modes.
This patch makes libm-test.inc tests of most functions use ALL_RM_TEST
unless there was some reason to defer that change for a particular
function.
I started out planning to defer the change for pow (bug 16315), cexp /
ccos / ccosh / csin / csinh (likely fallout from exp, bug 16284) and
cpow (exact expectations for signs of exact zero results not wanted).
Testing on x86_64 and x86 showed additional failures for acosh, cacos,
catan, catanh, clog, clog10, jn, log, log10, log1p, log2, tgamma, yn,
so making the change for those functions was deferred as well, pending
investigation to show which of these represent distinct bugs (some
such bugs may already be filed) and appropriate fixing / XFAILing.
Failures include wrong signs of zero results, errors slightly above
the 9ulp bound (in such cases it may make sense for functions to set
round-to-nearest internally to reduce error accumulation), large
errors and incorrect overflow/underflow for the rounding mode (with
consequent missing errno settings in some cases). It's possible some
could be issues with test expectations, though I didn't notice any
that were obviously like that (I added NO_TEST_INLINE for cases that
were failing for ildoubl on x86 and where it seemed reasonable for
them to fail for the fast-math inlines).
There may of course be failures on other architectures for functions
that didn't fail on x86_64 or x86, in which case the usual rule
applies: file a bug (preferably identifying the underlying problem
function, in cases where function A calls function B and a problem
with function B may present in the test results for function A) if not
already in Bugzilla then fix or XFAIL.

Test scalbn and scalbln in all rounding modes, add more tests of negative arguments.
Continuing the move to systematically testing libm functions in all
rounding modes with ALL_RM_TEST, this patch converts the tests of
scalbn and scalbln to use that macro.
Those tests include cases of underflow and overflow, meaning the
expected results depend on the rounding mode. For convenience in
writing such tests manually, the patch adds the notation plus_oflow,
minus_oflow, plus_uflow and minus_uflow for overflowing / underflowing
results of each sign appropriate to the rounding mode being used, and
gen-libm-test.pl is made to substitute in the appropriate values. The
tests of underflow and overflow are extended to include negative
arguments to provide better coverage (otherwise minus_oflow and
minus_uflow wouldn't have been used at all).
(A subsequent patch will make ldexp use the scalbn tests, as those
functions are equivalent for binary floating point.)

Fix offset caching for streams and use it for ftell (BZ #16680)
The ftell implementation was made conservative to ensure that
incorrectly cached offsets never affect it. However, this causes
problems for append mode when a file stream is rewound. Additionally,
the 'clever' trick of using stat to get position for append mode files
caused more problems than it solved and broke old behavior. I have
described the various problems that it caused and then finally the
solution.
For a and a+ mode files, rewinding the stream should result in ftell
returning 0 as the offset, but the stat() trick caused it to
(incorrectly) always return the end of file. Now I couldn't find
anything in POSIX that specifies the stream position after rewind()
for a file opened in 'a' mode, but for 'a+' mode it should be set to
0. For 'a' mode too, it probably makes sense to keep it set to 0 in
the interest of retaining old behavior.
The initial file position for append mode files is implementation
defined, so the implementation could either retain the current file
position or move the position to the end of file. The earlier ftell
implementation would move the offset to end of file for append-only
mode, but retain the old offset for a+ mode. It would also cache the
offset (this detail is important). My patch broke this and would set
the initial position to end of file for both append modes, thus
breaking old behavior. I was ignorant enough to write an incorrect
test case for it too.
The Change:
I have now brought back the behavior of seeking to end of file for
append-only streams, but with a slight difference. I don't cache the
offset though, since we would want ftell to query the current file
position through lseek while the stream is not active. Since the
offset is moved to the end of file, we can rely on the file position
reported by lseek and we don't need to resort to the stat() nonsense.
Finally, the cache is always reliable, except when there are unflished
writes in an append mode stream (i.e. both a and a+). In the latter
case, it is safe to just do an lseek to SEEK_END. The value can be
safely cached too, since the file handle is already active at this
point. Incidentally, this is the only state change we affect in the
file handle (apart from taking locks of course).
I have also updated the test case to correct my impression of the
initial file position for a+ streams to the initial behavior. I have
verified that this does not break any existing tests in the testsuite
and also passes with the new tests.

Do not terminate default test runs on test failure.
This patch is an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> and
<https://sourceware.org/ml/libc-alpha/2014-03/msg00180.html>.
Normal practice for software testsuites is that rather than
terminating immediately when a test fails, they continue running and
report at the end on how many tests passed or failed.
The principle behind the glibc testsuite stopping on failure was
probably that the expected state is no failures and so any failure
indicates a problem such as miscompilation. In practice, while this
is fairly close to true for native testing on x86_64 and x86 (kernel
bugs and race conditions can still cause intermittent failures), it's
less likely to be the case on other platforms, and so people testing
glibc run the testsuite with "make -k" and then examine the logs to
determine whether the failures are what they expect to fail on that
platform, possibly with some automation for the comparison.
This patch switches the glibc testsuite to the normal convention of
not stopping on failure - unless you use stop-on-test-failure=y, in
which case it behaves essentially as it did before (and does not
generate overall test summaries on failure). Instead, the summary
tests.sum may contain tests that FAILed. At the end of the test run,
any FAIL or ERROR lines from tests.sum are printed, and then it exits
with error status if there were any such lines. In addition, build
failures will also cause the test run to stop - this has the
justification that those *do* indicate serious problems that should be
promptly fixed and aren't generally hard to fix (but apart from that,
avoiding the build stopping on those failures seems harder).
Note that unlike the previous patches in this series, this *does*
require people with automation around testing glibc to change their
processes - either to start using tests.sum / xtests.sum to track
failures and compare them with expectations (with or without also
using "make -k" and examining "make" logs to identify build failures),
or else to use stop-on-test-failure=y and ignore the new tests.sum /
xtests.sum mechanism. (If all you check is the exit status from "make
check", no changes are needed unless you want to avoid test runs
continuing after the first failure.)

hppa: Add _STACK_GROWS_* cases to pthread_attr_[sg]etstack.
This is one of a several NPTL patches to build glibc on hppa.
The pthread_attr_[sg]etstack functions are defined by POSIX as
taking a stackaddr that is the lowest addressable byte of the
storage used for the stack. However, the internal iattr variable
of the same name in NPTL is actually the final stack address
as usable in the stack pointer for the machine. Therefore the
NPTL implementation must add and subtract stacksize for
_STACK_GROWS_DOWN architectures. HPPA is a _STACK_GROWS_UP
architecture and doesn't need to add or subtract anything,
the stack address *is* the lowest addressable byte of the
storage.
Tested on hppa-linux-gnu, with no regressions.
Can't impact any other targets because of the conditionals.

Fix __ASSUME_PSELECT for MicroBlaze (bug 16642).
Reviewing (for all architectures, with a baseline kernel version of
2.6.32) the kernel support for features for which __ASSUME_* macros
would be affected by a move to 2.6.32 as minimum kernel version showed
up that __ASSUME_PSELECT was wrongly defined for MicroBlaze, despite
the corresponding syscall table entry not being wired up in the
MicroBlaze kernel.
This patch makes the MicroBlaze kernel-features.h undefine
__ASSUME_PSELECT. I'd also encourage wiring it up in the kernel (so
you can then make this #undef conditional, and eventually obsolete
once a recent-enough kernel is required). I suspect it wasn't wired
up because of the mistaken comment in asm/unistd.h "obsolete ->
sys_pselect7" (there is no such syscall as pselect7).

Provide correct buffer length to netgroup queries in nscd (BZ #16695)
The buffer to query netgroup entries is allocated sufficient space for
the netgroup entries and the key to be appended at the end, but it
sends in an incorrect available length to the NSS netgroup query
functions, resulting in overflow of the buffer in some special cases.
The fix here is to factor in the key length when sending the available

Fix MIPS libc_feresetround*_ctx to preserve exceptions.
Testing on mips64 showed missing underflow exceptions (from exp, for
example) in non-default rounding modes, caused by
libc_feresetround*_ctx wrongly restoring a saved environment without
preserving exceptions, when that's only valid for the _noex variants.
(I don't know why Steve didn't see this in his testing.) This patch
fixes this by using libc_feupdateenv_mips_ctx for the relevant macros
and removing the problem definitions.
The problem definitions aren't suitable for the _noex macros either
because they only discard exceptions in non-default rounding modes,
and while for some uses of *_noex/*_NOEX it doesn't matter whether
exceptions are discarded, dbl-64/e_remainder.c requires
SET_RESTORE_ROUND_NOEX to cause exceptions to be discarded. I think
the accumulated set of macros / functions for optimized exception /
rounding mode handling could do with a careful review by now, and
possible refactoring, and at least one new feature (extracting the
saved rounding mode from an environment / context variable - see
dbl-64/e_sqrt.c for a case where this could be used).
Tested mips64.

Fix nextafter overflow in non-default rounding modes (bug 16677).
ISO C requires the result of nextafter to be independent of the
rounding mode, even when underflow or overflow occurs. This patch
fixes the bug in various nextafter implementations that, having done
an overflowing computation to force an overflow exception (correct),
they then return the result of that computation rather than an
infinity computed some other way (incorrect, when the overflowing
result of arithmetic with that sign and rounding mode is finite but
the correct result is infinite) - generally by falling through to
existing code to return a value that in fact is correct for this case
(but was computed by an integer increment and so without generating
the exceptions required). Having fixed the bug, the previously
deferred conversion of nextafter testing in libm-test.inc to
ALL_RM_TEST is also included.
Tested x86_64 and x86; also spot-checked results of nextafter tests

Add libm-test.inc macro for all-rounding-modes testing.
This patch adds support in libm-test.inc for automatically running
tests of a function in all rounding modes, in the form of a macro
ALL_RM_TEST to loop over all rounding modes when running tests of a
function, and uses it for functions whose results should always be
independent of the rounding mode.
Conversion of tests of nextafter to ALL_RM_TEST was deferred because
trying that conversion showed up bug 16677. (Finding such a bug of
course illustrates the point of testing more systematically in all
rounding modes rather than only reactively when bugs get reported in a
particular function in a non-default mode.) Conversion of tests where
results can depend on the rounding mode will follow once I add
gen-libm-test.pl support for using different initializers for the
expected results for different rounding modes (again, some conversions
may need deferring until bugs are fixed, depending on how
straightforward they are to XFAIL in a particular context).
Some existing tests get run five times rather than four, with
round-to-nearest tests both run in that as default rounding mode and
also with it explicitly set with fesetround (FE_TONEAREST). This
duplication doesn't seem particularly useful, so ALL_RM_TEST only runs
tests four times.

Include all of <time.h> from <sched.h> for older standards (bug 16670).
This patch fixes one of the header namespace issues shown up by
conformtest, <sched.h> failing to expose all symbols from <time.h> as
required by older standards. The patch keeps the existing behavior if
__USE_XOPEN2K is defined (the default; POSIX.1-2001 was the version
that made it optional to expose these symbols), but ensures that all
the symbols from <time.h> are exposed if an older standard is
selected. Tested x86_64.

Count miscellaneous files built on host for testing as tests.
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00198.html> I
raised the question of counting miscellaneous dependencies of tests,
built on the host rather than the build system, as tests, so that when
test failures don't stop "make check" neither do those other builds on
the host, so that a flaky host doesn't stop "make check" from
producing a complete summary of test results. Brooks supported that
idea in <https://sourceware.org/ml/libc-alpha/2014-02/msg00301.html>.
This patch implements that change for all the examples I could find:
one message catalog in catgets/, locales in localedata/ and timezone

Make tests consistently use *.out output files.
This patch systematically renames miscellaneous tests so their outputs
use a *.out name (unless the test is just running some glibc program
with its conventional output file name, rather than a special program
at all, as in catgets tests generating *.cat). In the case of the
iconv test test-iconvconfig, output is redirected where it wasn't
before.
In various places the "generated" variable is updated to reflect the
revised test names; in iconvdata/Makefile a typo (mmtrace-tst-loading)
is also fixed. resolv/Makefile sets both "generate" (which appears
unused) and "generated". Bitrot in the settings of these variables
could no doubt be fixed so that "make clean" after build and testing
leaves results the same as after configure (and indeed the
tests-special / xtests-special variables could be used to simplify
things, by removing those files automatically rather than listing them
manually in these variables), and "make distclean" leaves an empty
build directory, but right now it appears various files don't get
deleted. I think they are liable to continue to bitrot in the absence
of routine testing that these targets actually work, given that
building in the source directory isn't supported and that was the main
use of such makefile targets.

Generate overall summary of test results.
This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00197.html>, makes
testsuite runs generate an overall summary of test results.
A new script merge-test-results.sh deals both with collecting results
within a directory to a file with all the results from that directory,
and collecting the results from subdirectories into a single overall
file (there's not much in common between the two modes of operation of
the script, but it seemed silly to have two separate scripts for
this). Within a directory, missing results produce UNRESOLVED lines;
at top level, missing results for a whole directory produce an ERROR
line (since toplevel can't identify what the specific missing tests
are in this case).
Note that this does not change the rules for when "make" considers
there has been an error, or terminates, so unexpected failures will
still cause make to terminate, or, with -k, mean the commands for
"tests" don't get run because of failure of a dependency.

conformtest: split up running of tests from makefile.
This patch changes the logic by which header conformance tests are run
so that the makefiles run the tests for each (standard, header) pair
separately rather than as a single test (there are 518 such pairs
being tested at present).
Since these tests are slow and previously couldn't be run in parallel,
this obviously speeds up the whole test run significantly when using
parallel testing. There are other benefits. These tests can now be
marked as expected to fail at the level of (standard, header) pairs,
meaning that regressions introduced by a header change are much more
likely to be spotted (of course, such a regression could be a bug in
the header or in the expectations, most of which have not been
properly checked against the relevant standards).
The patch introduces lists in conform/Makefile of the headers to test
for each standard, with a new (quick) test for each standard that the
list agrees with the set of headers for which there are in fact
nonempty expectations for that standard. This means that each of the
518 pairs being tested is actually something meaningful to test rather
than a null test. I also hope to use these lists of headers in
various standards in future tests for namespace violations where a
function in a standard is implemented to call a non-reserved name for
a function outside that standard.
Although there are a lot of tests now marked as expected to fail, I
expect most of those to be easy to fix (whether with fixes to the
expectations, the headers or both - if fixing a header bug, of course
file it in Bugzilla first); only a limited number are likely to
reflect actual missing features in glibc.
Tested x86_64 (GCC 4.7 branch). It's quite possible some failures
vary from platform to platform, in which case either additional XFAILs
can be added here, or platform-specific header bugs (if applicable)
the failures show up can be fixed. I made XFAILs unconditional for
tests that should only fail for GCC 4.6 and earlier; we could make the
GCC version available in the makefiles and condition these, but simply
moving the XFAILing to a finer granularity seems a clear improvement
on the previous state of the whole of conformtest being XFAILed.

Enumerate tests with special rules in tests-special variable.
This patch is a revised and updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>.
In order to generate overall summaries of the results of all tests in
the glibc testsuite, we need to identify and concatenate the files
with the results of individual tests.
Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this.
However, the normal glibc approach is explicit enumeration of the
expected set of files with a given property, rather than all files
matching some pattern like that. Furthermore, we would like to be
able to mark tests as UNRESOLVED if the file with their results is for
some reason missing, and in future we would like to be able to mark
tests as UNSUPPORTED if they are disabled for a particular
configuration (rather than simply having them missing from the list of
tests as at present). Such handling of tests that were not run or did
not record results requires an explicit enumeration of tests.
For the tests following the default makefile rules, $(tests) (and
$(xtests)) provides such an enumeration. Others, however, are added
directly as dependencies of the "tests" and "xtests" makefile
targets. This patch changes the makefiles to put them in variables
tests-special and xtests-special, with appropriate dependencies on the
tests listed there then being added centrally.
Those variables are used in Rules and so need to be set before Rules
is included in a subdirectory makefile, which is often earlier in the
makefile than the dependencies were present before. We previously
discussed the question of where to include Rules; see the question at
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a
discussion in
<https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why
Rules is included early rather than late in subdirectory makefiles.
It was necessary to avoid an indirection through the check-abi target
and get the check-abi-* targets for individual libraries into the
tests-special variable. The intl/ test $(objpfx)tst-gettext.out,
previously built only because of dependencies from other tests, was
also added to tests-special for the same reason.
The entries in tests-special are the full makefile targets, complete
with $(objpfx) and .out. If a future change causes tests to be named
consistently with a .out suffix, this can be changed to include just
the path relative to $(objpfx), without .out.
Tested x86_64, including that the same set of files is generated in
the build directory by a build and testsuite run both before and after
the patch (except for changes to the
elf/tst-null-argv.debug.out.<number> file name), and a build with
run-built-tests=no to verify there aren't any more obvious instances
of the issue Marcus Shawcroft reported with a previous version in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>.

Prepare libm-test.inc structures for multi-rounding-mode testing.
At present, libm-test.inc tests are run in multiple rounding modes by
having a separate array for each rounding mode (which might or might
not have the same test inputs as the other such arrays), a separate
function calling a RUN_TEST_LOOP_* macro over that array, and a
separate call to that function in main. The number of functions
tested in multiple rounding modes has gradually increased as
rounding-mode-specific bugs have been found and fixed in different
functions.
It would be better to be able to use a single macro call, in a single
function, to run tests for a function over all rounding modes, with
this being done for all libm functions except in cases where it's
deferred until some bugs can be fixed because XFAILing all affected
tests would be painful (that's why the full set of pow tests isn't
currently run in all rounding modes). This patch helps prepare for
that by making the structures storing expected results for tests store
results for all four rounding modes. After this patch, the results
for all modes are just duplicates, but tests access the appropriate
field in the structure, so helping to pave the way for when the fields
stop being duplicates and multiple rounding modes can be tested from a
single array. Tests might in future specify a single set of results,
to be used in all rounding modes; separate results for each rounding
mode, specified manually; or use of auto-libm-tests-* to generate
results for each rounding mode.

Don't define __ASSUME_UTIMES for linux-generic architectures.
The __ASSUME_UTIMES macro describes whether the utimes syscall is
present. For linux-generic architectures, it isn't (utimensat is
instead), so the macro should not be defined for them; this patch
removes the spurious definitions for such architectures. (Those
definitions don't actually cause any user-visible bug, because
futimes.c doesn't use __ASSUME_UTIMES if __ASSUME_UTIMENSAT is
defined, and futimesat.c and utimes.c are overridden for
linux-generic, but the definitions are still logically incorrect.)

Adjust how gen-auto-libm-tests handles before-rounding/after-rounding cases.
This patch changes gen-auto-libm-tests so that, when generating test
results that depend on whether the architecture has before-rounding or
after-rounding tininess detection, the :before-rounding or
:after-rounding conditions go on the exception / errno flags
generated, rather than generating two separate lines in
auto-libm-test-out for e.g. flt-32:before-rounding and
flt-32:after-rounding.
The rationale for this is as follows. It would be desirable for
testing a libm function in all rounding modes to require just one
function and array in libm-test.inc, not four (or five), with the
array of test data including expected results for all rounding modes
rather than separate arrays for each rounding mode that also need to
repeat all the test inputs. For gen-libm-test.pl to generate data for
such an array from auto-libm-test-out, it would be helpful if each
(format, test input) pair has exactly four lines in
auto-libm-test-out, one for each rounding mode, rather than some
rounding modes having just one line and some having two because the
exceptions depend on tininess detection.
