* [BZ #22244] Fix yn(n,0) without SVID wrapperSzabolcs Nagy2017-10-042-8/+8
| | | | | | | | | | Without SVID compat wrapper yn(n,0) and ynf(n,0) does not raise the divide-by-zero excpetion and it may return inf with the wrong sign for n < 0. [BZ #22244] * sysdeps/ieee754/dbl-64/e_jn.c (__ieee754_yn): Fix x == 0 case. * sysdeps/ieee754/flt-32/e_jnf.c (__ieee754_ynf): Likewise.
* [BZ #22243] fix log2(0) and log(10) in downward roundingSzabolcs Nagy2017-10-042-2/+2
| | | | | | | | | On 64bit targets if the SVID compat wrapper is suppressed (e.g. static linking) then log2(0) and log10(0) returned inf instead of -inf. [BZ #22243] * sysdeps/ieee754/dbl-64/wordsize-64/e_log10.c (__ieee754_log10): Use fabs. * sysdeps/ieee754/dbl-64/wordsize-64/e_log2.c (__ieee754_log2): Likewise.

| | | | | | | | | Don't use "leal main@GOTOFF(%ebx), %eax" since main may be in a shared object. Linker will convert "movl main@GOT(%ebx), %eax" to "leal main@GOTOFF(%ebx), %eax" if main is defined locally. * sysdeps/i386/start.S: Replace "leal main@GOT(%ebx), %eax" with "movl main@GOTOFF(%ebx), %eax".
* Revert x86: Allow undefined _DYNAMIC in static executableH.J. Lu2017-10-032-18/+4
| | | | | | | | | | | | This code is used in non-PIE static executable and static PIE. It checks if _DYNAMIC is undefined before using it to compute load address.

* Use libm_alias_double for dbl-64 modf.Joseph Myers2017-10-035-23/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes dbl-64 modf use libm_alias_double. Both the dbl-64 and dbl-64/wordsize-64 versions are changed, and the ldbl-opt version is changed to define the libc compat symbol only. Because of multiarch wrappers, the changed implementations are made not to define aliases at all if __modf is defined as a macro, as with other functions, so avoiding duplicate compat symbols while allowing those wrappers to be simplified.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes dbl-64 logb use libm_alias_double.

| | | | | | | | | | | | | | | | | | This patch makes dbl-64 frexp use libm_alias_double. Both the dbl-64 and dbl-64/wordsize-64 versions are changed; the ldbl-opt version is made to define only the libc frexpl compat symbol, now the generic code handles the libm compat symbol automatically.

* Add C++ versions of iscanonical for ldbl-96 and ldbl-128ibm (bug 22235)Gabriel F. T. Gomes2017-10-033-3/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All representations of floating-point numbers in types with IEC 60559 binary exchange format are canonical. On the other hand, types with IEC 60559 extended formats, such as those implemented under ldbl-96 and ldbl-128ibm, contain representations that are not canonical. TS 18661-1 introduced the type-generic macro iscanonical, which returns whether a floating-point value is canonical or not. In Glibc, this type-generic macro is implemented using the macro __MATH_TG, which, when support for float128 is enabled, relies on __builtin_types_compatible_p to select between floating-point types. However, this use of iscanonical breaks C++ applications, because the builtin is only available in C mode. This patch provides a C++ implementation of iscanonical that relies on function overloading, rather than builtins, to select between floating-point types. Unlike the C++ implementations for iszero and issignaling, this implementation ignores __NO_LONG_DOUBLE_MATH. The double type always matches IEC 60559 double format, which is always canonical. Thus, when double and long double are the same (__NO_LONG_DOUBLE_MATH), iscanonical always returns 1 and is not implemented with __MATH_TG. Tested for powerpc64, powerpc64le and x86_64. [BZ #22235] * math/math.h: Trivial fix for unbalanced parentheses in comment. * math/Makefile [CXX] (tests): Add test-math-iscanonical.cc. (CFLAGS-test-math-iscanonical.cc): New variable. * math/test-math-iscanonical.cc: New file. * sysdeps/ieee754/ldbl-96/bits/iscanonical.h (iscanonical): Provide a C++ implementation based on function overloading, rather than using __MATH_TG, which uses C-only builtins. * sysdeps/ieee754/ldbl-128ibm/bits/iscanonical.h (iscanonical): Likewise. * sysdeps/powerpc/powerpc64le/Makefile (CFLAGS-test-math-iscanonical.cc): New variable.
* Use libm_alias_double for more dbl-64 functions.Joseph Myers2017-10-0327-140/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes more dbl-64 functions use libm_alias_double to define function aliases. Specifically, it makes the change for functions with dbl-64/wordsize-64 versions, changing both the dbl-64 and dbl-64/wordsize-64 versions and removing the ldbl-opt wrappers. Functions are excluded from this patch if there are complications because of versions of those functions also present in libc, or architecture-specific wrappers round these files. Tested for x86_64, and with build-many-glibcs.py. Installed stripped shared libraries are unchanged except for alpha (where increased use of dbl-64/wordsize-64 files, where previously ldbl-opt files that wrapped dbl-64 files were used, was expected to result in different, better code). * sysdeps/ieee754/dbl-64/s_ceil.c: Include <libm-alias-double.h>.

* Introduce NO_RTLD_HIDDEN, make hurd use it instead of NO_HIDDENSamuel Thibault2017-10-033-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the Hurd, the rtld needs to see its own dumb versions of a few functions (defined in sysdeps/mach/hurd/dl-sysdep.c) overridden by libc's versions once loaded. rtld should thus not have hidden attribute for these. To achieve this, the Hurd port used to just define NO_HIDDEN, which disables it completely. For now, this changes that to disabling it for all rtld functions, for simplicity.

* Use libm_alias_double for some dbl-64 functions.Joseph Myers2017-09-2940-206/+52

This patch deliberately limits what functions are converted so that it can be verified by comparison of stipped binaries. Specifically, atan and tan are excluded because they first need converting to being weak aliases; fma is omitted as it has additional complications with versions in other directories (removing the ldbl-opt version can e.g. cause the ldbl-128 version to be used instead of dbl-64); and functions that have both dbl-64/wordsize-64 and ldbl-opt versions are excluded because ldbl-opt currently always wraps dbl-64 function versions, so changing those will result in platforms using both ldbl-opt and dbl-64/wordsize-64 (i.e. alpha) starting to use the dbl-64/wordsize-64 versions of those functions (which is good, as an optimization, but still best separated from the present patch to get better validation). Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/dbl-64/s_asinh.c: Include <libm-alias-double.h>.

* arm: Update elf_machine_load_address for static PIEH.J. Lu2017-09-291-1/+11
| | | | | | | | | | When --enable-static-pie is used to configure glibc, we need to use _dl_relocate_static_pie to compute load address in static PIE. * sysdeps/arm/dl-machine.h (elf_machine_load_address): Use _dl_relocate_static_pie instead of _dl_start to compute load address in static PIE. Return 0 if _DYNAMIC is undefined for static executable.
* mips: Update elf_machine_load_address for static PIEH.J. Lu2017-09-291-0/+5
| | | | | | | | | mips uses a local label to compute load address, which works with static PIE. We just need to return 0 if _DYNAMIC is undefined for static executable. * sysdeps/mips/dl-machine.h (elf_machine_dynamic): Return 0 if _DYNAMIC is undefined for static executable.
* arm: Check PIC instead of SHARED in start.SH.J. Lu2017-09-291-2/+2
| | | | | | | Since start.o may be compiled as PIC, we should check PIC instead of SHARED. * sysdeps/arm/start.S (_start): Check PIC instead of SHARED.
* Update x86_64 libm-test-ulps.Joseph Myers2017-09-291-2/+2
| | | | * sysdeps/x86_64/fpu/libm-test-ulps: Update.
