* Use libm_alias_double for more dbl-64 functions.Joseph Myers2017-10-0328-140/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>.

| | | | | | | | | | | The compat remainder code is no longer built for !LIBM_SVID_COMPAT targets, but the legacy drem, dremf and dreml symbols should be still defined since removing them may break existing code, so keep them as aliases in the non-compat remainder code. * math/w_remainder.c: New file. * math/w_remainderf.c: New file. * math/w_remainderl.c: New file.

* Introduce NO_RTLD_HIDDEN, make hurd use it instead of NO_HIDDENSamuel Thibault2017-10-0315-14/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. See Roland's comment on https://sourceware.org/bugzilla/show_bug.cgi?id=15605#c5 The ld.so numbers remain at 8 .rel.plt 000000c8 00000c24 00000c24 00000c24 2**2 CONTENTS, ALLOC, LOAD, READONLY, DATA 9 .plt 000001a0 00000cf0 00000cf0 00000cf0 2**4 CONTENTS, ALLOC, LOAD, READONLY, CODE 10 .plt.got 00000010 00000e90 00000e90 00000e90 2**3 CONTENTS, ALLOC, LOAD, READONLY, CODE 18 .got.plt 00000070 0002d000 0002d000 0002c000 2**2 CONTENTS, ALLOC, LOAD, DATA which is about 3 times as much as on Linux.

* Use libm_alias_double for dbl-64 atan, tan.Joseph Myers2017-10-025-20/+11
| | | | | | | | | | | | | | | | | | | This patch makes the dbl-64 atan and tan implementations use libm_alias_double, removing the corresponding ldbl-opt wrappers. Tested for x86_64, and with build-many-glibcs.py. Installed stripped shared libraries are unchanged on non-ldbl-opt platforms. For ldbl-opt configurations, the patch has the effect of causing compat_symbol to define atanl and tanl in terms of __atan and __tan instead of in terms of atan and tan, which is enough to change the installed stripped libm.so. * sysdeps/ieee754/dbl-64/s_atan.c: Include <libm-alias-double.h>.

* Make dbl-64 atan and tan into weak aliases.Joseph Myers2017-10-0211-16/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the dbl-64 implementations of atan and tan into weak aliases of __atan and __tan, in preparation for making them use libm_alias_double. Consequent changes are made to the x86_64 multiarch versions wrapping round them (with the dbl-64 functions, like other such functions, being made not to define their aliases at all if __atan or __tan are defined as macros by an including file). Tested for x86_64, and with build-many-glibcs.py. * sysdeps/ieee754/dbl-64/s_atan.c (atan): Rename to __atan and define as weak alias of __atan. Do not define any aliases if [__atan].
