2017-09-01Obsolete pow10 functions.Joseph Myers
This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates. Tested for x86_64, and with build-many-glibcs.py. * manual/math.texi (pow10): Do not document. (pow10f): Likewise.

2017-09-01linux: Implement tmpfile with O_TMPFILE (BZ#21530)Adhemerval Zanella
This patch adds O_TMPFILE support to tmpfile on Linux. This is similar to the previous suggestion by Andreas Schwab [1] with the difference the file descriptor creation is parameterized to compartmentalize Linux only open flags (O_TMPFILE) on sysdeps.

2017-09-01getaddrinfo: Fix error handling in gethosts [BZ #21915] [BZ #21922]Florian Weimer
The old code uses errno as the primary indicator for success or failure. This is wrong because errno is only set for specific combinations of the status return value and the h_errno variable.

2017-09-01getaddrinfo: In gaih_inet, use h_errno for certain status values onlyFlorian Weimer
h_errno is not set for NSS_STATUS_SUCCESS, so its value might not be accurate at this point.
2017-09-01getaddrinfo: Properly set errno for NSS function lookup failureFlorian Weimer
2017-09-01getaddrinfo: Use &h_errno has the h_errno pointerFlorian Weimer
This simplifies the code because it is not necessary to propagate the temporary h_errno value to the thread-local variable. It also increases compatibility with NSS modules which update only one of the two places.
2017-09-01getaddrinfo: Use &errno has the errno pointerFlorian Weimer
Similar code in nss/getXXbyYY_r.c is already using &errno as the argument.

2017-08-31Remove NO_CANCELLATION macroAdhemerval Zanella
The NO_CANCELLATION macro is used currently on generic headers to define non cancellable syscalls and on Linux fcntl to implement the non cancellable variation. Former should be single-handled by not-cancel.h header and former could be simplified build both cancellable and non cancellable for default objects and alias the non-cancellable to default one for rtld ones (since Linux already support cancellation as default). This patch thus removes the NO_CANCELLATION macro and its usage. The generic non cancellable fcntl is route to internal fcntl. Checked on x86_64-linux-gnu and i686-linux-gnu. Also checked with a build again major ABIs. * sysdeps/generic/not-cancel.h (NO_CANCELLATION): Remove macro. * sysdeps/unix/sysv/linux/aarch64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/alpha/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/arm/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/hppa/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/microblaze/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/mips/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/nios2/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/powerpc/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/sh/sysdep-cancel.h (NO_CANCELLATION): Likewise * sysdeps/unix/sysv/linux/sparc/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/tile/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep-cancel.h (NO_CANCELLATION): Likewise. * sysdeps/unix/sysv/linux/not-cancel.h (__fcntl_nocancel): Add hidden prototype. * sysdeps/unix/sysv/linux/fcntl.c (__fcntl_nocancel): Define only for !IS_IN (rtld) and remove NO_CANCELLATION usage.

2017-08-31Simplify NAN definitions.Joseph Myers
Similar to my patches for HUGE_VAL and INFINITY. this patch eliminates the bits/nan.h headers. __builtin_nanf ("") is used to define NAN for GCC 3.3 and later; the fallback is (0.0f / 0.0f), which is a constant expression for a quiet NaN of type float, but raises a spurious "invalid" exception outside static initializers, which seems the best that can be done purely in standard C. Again, if anyone actually uses a compiler with its own incompatible extension for producing a constant quiet NaN, we can add compiler conditionals. Tested for x86_64. * math/math.h [__USE_ISOC99] (NAN): Define directly here. Do not include <bits/nan.h>. * math/Makefile (headers): Remove bits/nan.h. * bits/nan.h: Remove. * sysdeps/ieee754/bits/nan.h: Likewise. * sysdeps/mips/bits/nan.h: Likewise.
2017-08-31Simplify INFINITY definitions.Joseph Myers
Similar to my patch for HUGE_VAL, this patch eliminates the bits/inf.h headers and just unconditionally uses the same definitions as the sysdeps/ieee754 version did (__builtin_inff () for GCC >= 3.3, otherwise HUGE_VALF), directly in math.h, so removing an unnecessary level of indirection. Tested for x86_64. * math/math.h [__USE_ISOC99] (INFINITY): Define directly here. Do not include <bits/inf.h>. * math/Makefile (headers): Remove bits/inf.h. * bits/inf.h: Remove. * sysdeps/ieee754/bits/inf.h: Likewise.
2017-08-31Simplify HUGE_VAL definitions.Joseph Myers
There are various bits/huge_val*.h headers to define HUGE_VAL and related macros. All of them use __builtin_huge_val etc. for GCC 3.3 and later. Then there are various fallbacks, such as using a large hex float constant for GCC 2.96 and later, or using unions (with or without compound literals) to construct the bytes of an infinity, with this last being the reason for having architecture-specific files. Supporting TS 18661-3 _FloatN / _FloatNx types that have the same format as other supported types will mean adding more such macros; needing to add more headers for them doesn't seem very desirable. The fallbacks based on bytes of the representation of an infinity do not meet the standard requirements for a constant expression. At least one of them is also wrong: sysdeps/sh/bits/huge_val.h is producing a mixed-endian representation which does not match what GCC does. This patch eliminates all those headers, defining the macros directly in math.h. For GCC 3.3 and later, the built-in functions are used as now. For other compilers, a large constant 1e10000 (with appropriate suffix) is used. This is like the fallback for GCC 2.96 and later, but without using hex floats (which have no apparent advantage here). It is unambiguously valid standard C for all floating-point formats with infinities, which covers all formats supported by glibc or likely to be supported by glibc in future (C90 DR#025 said that if a floating-point format represents infinities, all real values lie within the range of representable values, so the constraints for constant expressions are not violated), but may generate compiler warnings and wouldn't handle the TS 18661-1 FENV_ROUND pragma correctly. If someone is actually using a compiler with glibc that does not claim to be GCC 3.3 or later, but which has a better way to define the HUGE_VAL macros, we can always add compiler conditionals in with alternative definitions. I intend to make similar changes for INF and NAN. The SNAN macros already just use __builtin_nans etc. with no fallback for compilers not claiming to be GCC 3.3 or later. Tested for x86_64. * math/math.h: Do not include bits/huge_val.h, bits/huge_valf.h, bits/huge_vall.h or bits/huge_val_flt128.h. (HUGE_VAL): Define directly here. [__USE_ISOC99] (HUGE_VALF): Likewise.
