The changes to fix bug 20729 introduced an error which removed an
ignore diagnostic from -O2 by using the new -Os related macro.
This broke ppc64 builds. This commit fixes the mistake.
Tested on x86, x86_64, ppc64, ppc64le, arm, aarch64, and s390x.
Bug 19673 reports that the documentation of clog10 is incorrect, both
failing to include the division by log (10) in the imaginary part and,
in the non-TeX version of the equation only, describing the LHS as log
rather than log10.
This patch fixes both issues. Note: I think it's appropriate that the
LHS says log10 not clog10, and that the cexp and clog descriptions
referred to in a comment in that bug report similarly say exp and log;
this is a mathematical description not a literal C one.
Tested for x86_64.
[BZ #19673]
* manual/math.texi (Exponents and Logarithms): Correct description
of clog10.
The original fix for bug 20729 failed to include
libc-internal.h in the files that needed them and
this caused build failures on machines that don't
implicitly include this header. This commit fixes
that by following the consensus rule that a header,
if needed, should always be directly included.
This commit adds a new DIAG_IGNORE_Os_NEEDS_COMMENT which is only
enabled when compiling with -Os. This allows developers working on
-Os enabled builds to mark false-positive warnings without impacting the
warnings emitted at -O2.
Then using the new DIAG_IGNORE_Os_NEEDS_COMMENT we fix 6 warnings
generated with GCC 5 to get -Os builds working again.
The test case dlfcn/bug-atexit3-lib.cc calls write and doesn't check the
result. When building with GCC 6.2, this generates a warning in 'make
check', which is treated as an error. This patch replaces the call to
write with a call to write_message.
Tested for powerpc64le.
TS 18661-1 defines SNAN macros for signaling NaN values, suitable for
use in static initializers. This patch adds them to glibc's <math.h>
(provided you are building with GCC 3.3 or later; no attempt is made
to provide any kind of nonconforming fallback for older compilers
without the __builtin_nans functions).
Tested for x86_64 and x86.

The test math/test-nan-overflow uses malloc without including
stdlib.h. On -Os builds for i486 the header inclusion order
is altered enough that the test fails to build because of the
warning which is turned into an error.
The obvious fix is to include stdlib.h since malloc is being
used directly.

relinking the shared library if it references IFUNC function defined

The strtod function should raise the "inexact" exception when its
result is inexact, but fails to do so except in the case of underflow
or overflow. This patch fixes it to do so for all inexact results.
tst-strtod-round is extended to test for this exception; the generator
is fixed to properly mark inexact results as such in the case where
the inexactness is from the mpfr_subnormalize step.

TS 18661-1 defines canonicalize functions to produce a canonical
version of a floating-point representation. This patch implements
these functions for glibc.
As with the iscanonical macro, these functions are oriented to the
decimal floating-point case, where some values have both canonical and
noncanonical representations. However, the functions have a return
value that says whether they succeeded in storing a canonical result;
thus, they can fail for the case of an invalid representation (while
still not making any particular choice from among multiple equally
canonical valid representations of the same value). Since no
floating-point formats in glibc actually have noncanonical valid
representations, a type-generic implementation of these functions can
be used that expects iscanonical to return 0 only for invalid
representations. Now that iscanonical is used within libm.so,
libm_hidden_proto / libm_hidden_def are added for __iscanonicall.
The definition of these functions is intended to correspond to a
convertFormat operation to the same floating-point format. Thus, they
convert signaling NaNs to quiet NaNs, raising the "invalid" exception.
Such a conversion "should" produce "the canonical version of that
signaling NaN made quiet".
libm-test.inc is made to check NaN payloads for the output of these
functions, a new feature (at some point manipulation functions such as
fabs and copysign should have tests added that verify payload
preservation for them). As however some architectures may not follow
the recommended practice of preserving NaN payloads when converting a
signaling NaN to quiet, a new math-tests.h macro
SNAN_TESTS_PRESERVE_PAYLOAD is added, and defined to 0 for non-NAN2008
MIPS; any other architectures seeing test failures for lack of payload
preservation in this case should also define this macro to 0. (If any
cases arise where the sign isn't preserved either, those should have a
similar macro added.)
The ldbl-96 and ldbl-128ibm tests of iscanonical are renamed and
adapted to test canonicalizel as well on the same representations.
Tested for x86_64, x86, mips64 and powerpc.

The function read_int, from printf-parse.h, parses an integer from a string
while avoiding overflows. It is used by other functions, such as vfprintf,
to avoid undefined behavior.
The function vfscanf (_IO_vfwscanf) parses an integer from the format
string, and can use read_int.
After the removal of __malloc_initialize_hook, newly compiled
Emacs binaries are no longer able to use these interfaces.
malloc_get_state is only used during the Emacs build process,
so we provide a stub implementation only. Existing Emacs binaries
will not call this stub function, but still reference the symbol.
The rewritten tst-mallocstate test constructs a dumped heap
which should approximates what existing Emacs binaries pass
to glibc malloc.
The IBM930, IBM933, IBM935 and IBM939 converters defined lookup
tables which were not constant. They also contained an
unnecessary pointer indirection.
The M_ARENA_MAX and M_ARENA_TEST macros are defined in malloc.c as
well as malloc.h, and the former is unnecessary. This patch removes
the duplicate. Tested on x86_64 to verify that the generated code
remains unchanged barring changed line numbers to __malloc_assert.
* malloc/malloc.c (M_ARENA_TEST, M_ARENA_MAX): Remove.
The manual incorrectly references sbrk as the method used to grow and
shrink heaps and the fact that M_TRIM_THRESHOLD and M_TOP_PAD control
that behavior. In reality, a heap may be grown or shrunk through
multiple methods depending on whether it is the main arena (in which
case sbrk is correct) or not (in which case, there are a number of
strategies including allocating an additional heap to grow an arena
and/or 'mprotect' a region to make it available for allocation).
Remove references to sbrk so that it covers the behavior more
accurately.
* manual/memory.texi (M_TOP_PAD): Remove reference to sbrk.
(M_TRIM_THRESHOLD): Likewise.
The M_ARENA_* mallopt parameters are in wide use in production to
control the number of arenas that a long lived process creates and
hence there is no point in stating that this interface is non-public.
Document this interface and remove the obsolete comment.
* manual/memory.texi (M_ARENA_TEST): Add documentation.
(M_ARENA_MAX): Likewise.
* malloc/malloc.c: Remove obsolete comment.
The mallopt parameters manual does not mention the environment
variables that can be used to set these parameters at program startup.
Mention those environment variables for completeness.
* manual/memory.texi: Add environment variable alternatives to
setting mallopt parameters.
No code uses atomic_fetch_xor_release except for the upcoming
conditional variable rewrite. Therefore there is no user
visible bug here. The use of atomic_compare_and_exchange_bool_rel
is removed (since it doesn't exist anymore), and is replaced
by atomic_compare_exchange_weak_release.
We use weak_release because it provides better performance in
the loop (the weak semantic) and because the xor is release MO
(the release semantic). We don't reload expected in the loop
because atomic_compare_and_exchange_weak_release does this for
us as part of the CAS failure.
It is otherwise a fairly plain conversion that fixes building
the new condvar for 32-bit x86. Passes all regression tests
for x86.
ISO/IEC TS 18661-1 adds several functions in the strfrom family to stdlib.
This patch adds strfromd, strfromf, and strfroml. This is being done in
preparation for the new floating-point type, float128. The added functions
convert a floating-point value into a string, with configurable format.
Building glibc for powerpc64 with recent (2.27.51.20161012) binutils,
with multi-arch enabled, I get the error:
../sysdeps/powerpc/powerpc64/power6/memset.S: Assembler messages:

Indeed, cmpli is documented as a four-operand instruction, and looking
at nearby code it seems likely cmpldi was intended. This patch fixes
this powerpc64 code accordingly, and makes a corresponding change to
the powerpc32 code.
Tested for powerpc, powerpc64 and powerpc64le by Tulio Magno Quites
Machado Filho

Although conceptually correct for p{read,write}{64} offset argument passing,
sh4 implementation does not generate the correct expected code. The
__ALIGNMENT_ARG redefinition is incorrect for two reasons: 1. the
kernel-features.h header is included multiple times (since it contains no
guards) and 2. the value it redefines is also incorrect (should be '0, '
instead of empty definition).
This patch fixes it by adding another macro, SYSCALL_LL_PRW{64}, meant to be
used to pass the offset argument on p{read,write}64. It is basically the
already define SYSCALL_LL{64} plus __ALIGNMENT_ARG unless __ASSUME_PRW_DUMMY_ARG
is define. In this case an empty dummy argument is used regardless how
__ALIGNMENT_ARG is defined (sh4 case).
Checked on x86_64, i686, aarch64, armhf, and powerpc64le (basically a sanity
check). Also, John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> and
James Clarke <jrtc27@jrtc27.com> help me check on a debian sh4 bootstrap using
2.24 plus this patch to verify it also corrected fixed the regression issue.
I also verified the generated object for a 2.24 build and master with this
patch for sh4 and both look identical.

It is still common to include system header files in an extern "C"
block. This means that exiting <math.h>'s own extern "C" block
is not sufficient to get back to C++ mode. Use an extern "C++"
wrapper instead.
This patch makes the sqrt benchmark use -fno-builtin, as already done
for benchmarks of ffs and ffsll, so that it actually benchmarks the
glibc function as (presumably) intended even in the presence of the
compiler inlining sqrt.
Tested for x86_64 and also used for benchmarking my ARM sqrt patch.
* benchtests/Makefile (CFLAGS-bench-sqrt.c): New variable.
Some of the masks are wrong, and the naming is confusing.
There are two basic cases we really care about:
1. Stacking a new rounding mode when running certain
sections of code, and pausing exception handling.
2. Likewise, but discarding any exceptions which occur
while running under the new rounding mode.
libc_feholdexcept_setround_ppc_ctx has been removed as it basically
does the same thing as libc_feholdsetround_ppc_ctx but also clearing
any sticky bits. The restore behavior is what differentiates these
two cases as the SET_RESTORE_ROUND{,_NOEX} macros will either merge
or discard all exceptions occurring during scope of their usage.
Likewise, there are a number of routines to swap, replace,
or merge FP environments. This change reduces much of
the common and sometimes wrong code.
Tested on ppc64le, with results before and after.
This patch makes ARM sqrt and sqrtf use the VSQRT VFP square root
instruction when available, instead of much larger generic code for
computing square roots.
Now, GCC will normally inline sqrt calls except for negative arguments
where errno needs to be set, and because the benchtests fail to use
-fno-builtin that means no significant difference in benchmark results
for sqrt (note, however, there are lots of __ieee754_sqrt calls
internally in libm, which are *not* inlined - although some
architectures define __ieee754_sqrt in their math_private.h for that
purpose, ARM doesn't - so improving out-of-line sqrt performance is
still relevant to those other functions, if not for most ordinary
direct users of sqrt). With the benchtests changed to use
-fno-builtin for sqrt tests, typical performance results before the
change are ("max" is wildly varying in any case):
"duration": 9.88358e+09,
"iterations": 4.8783e+07,
"max": 457.764,
"min": 183.105,

The powerpc (hard-float) implementations of copysignl, both 32-bit and
64-bit, raise spurious "invalid" exceptions when the first argument is
a signaling NaN. copysign functions should never raise exceptions
even for signaling NaNs.
The problem is the use of an fcmpu instruction to test the sign of the
high part of the long double argument. This patch fixes the functions
to use fsel instead (as used for fabsl following my fixes for a
similar bug there), or to examine the integer representation for older
32-bit processors without fsel.
Tested for powerpc64 and powerpc32 (configurations with and without
fsel used).

TS 18661-1 defines functions for manipulating the payloads of NaNs.
This patch implements the getpayload functions for glibc; these
extract the NaN payload (from an argument passed as a pointer, for
which corresponding libm-test support is added) and return it in the
same floating-point type. The return value of these functions is
unspecified for non-NaN arguments; the patch does the simplest thing
to implement, which is that the functions do not check whether the
argument is a NaN and just treat the relevant bits of the
representation as a payload regardless. A conversion from integer to
floating-point is used to produce the required return value, except in
the ldbl-128 case; as 128-bit integers are not supported for all
configurations using ldbl-128, the code constructs the required
floating-point representation of the return value directly instead.
Tested for x86_64, x86, mips64 and powerpc.
