* Use round functions not __round functions in glibc libm.Joseph Myers2018-09-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __round functions to call the corresponding round names instead, with asm redirection to __round when the calls are not inlined. An additional complication arises in sysdeps/ieee754/ldbl-128ibm/e_expl.c, where a call to roundl, with the result converted to int, gets converted by the compiler to call lroundl in the case of 32-bit long, so resulting in localplt test failures. It's logically correct to let the compiler make such an optimization; an appropriate asm redirection of lroundl to __lroundl is thus added to that file (it's not needed anywhere else). Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (round): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_round.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_roundf.c: Likewise. * sysdeps/ieee754/dbl-64/s_round.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_round.c: Likewise. * sysdeps/ieee754/float128/s_roundf128.c: Likewise. * sysdeps/ieee754/flt-32/s_roundf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_roundl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_roundl.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_round.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_roundf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_round.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_roundf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_round.c: Likewise. * sysdeps/riscv/rvf/s_roundf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_roundl.c: Likewise.

* Use libm_alias_double for aarch64.Joseph Myers2017-11-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes aarch64 libm function implementations use libm_alias_double to define function aliases.

* Relocate AArch64 from ports to libc.Marcus Shawcroft2014-02-111-0/+21
This patch moves the AArch64 port to the main sysdeps hierarchy. The move is essentially: git mv ports/sysdeps/aarch64 sysdeps/aarch64 git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64 The README is updated and I've updated ChangeLog.aarch64 along the lines of the ARM move. The AArch64 build has been tested to confirm that there were no changes in objdump -dr output or the shared objects.
