2018-09-28Remove unnecessary math_private.h includes.Joseph Myers
After my changes to move various macros, inlines and other content from math_private.h to more specific headers, many files including math_private.h no longer need to do so. Furthermore, since the optimized inlines of various functions have been moved to include/fenv.h or replaced by use of function names GCC inlines automatically, a missing math_private.h include where one is appropriate will reliably cause a build failure rather than possibly causing code to be less well optimized while still building successfully. Thus, this patch removes includes of math_private.h that are now unnecessary. In the case of two RISC-V files, the include is replaced by one of stdbool.h because the files in question were relying on math_private.h to get a definition of bool. Tested for x86_64 and x86, and with build-many-glibcs.py. * math/fromfp.h: Do not include <math_private.h>. * math/s_cacosh_template.c: Likewise. * math/s_casin_template.c: Likewise. * math/s_casinh_template.c: Likewise. * math/s_ccos_template.c: Likewise. * math/s_cproj_template.c: Likewise. * math/s_fdim_template.c: Likewise. * math/s_fmaxmag_template.c: Likewise. * math/s_fminmag_template.c: Likewise. * math/s_iseqsig_template.c: Likewise. * math/s_ldexp_template.c: Likewise. * math/s_nextdown_template.c: Likewise. * math/w_log1p_template.c: Likewise. * math/w_scalbln_template.c: Likewise. * sysdeps/aarch64/fpu/feholdexcpt.c: Likewise. * sysdeps/aarch64/fpu/fesetround.c: Likewise. * sysdeps/aarch64/fpu/fgetexcptflg.c: Likewise. * sysdeps/aarch64/fpu/ftestexcept.c: Likewise. * sysdeps/aarch64/fpu/s_llrint.c: Likewise. * sysdeps/aarch64/fpu/s_llrintf.c: Likewise. * sysdeps/aarch64/fpu/s_lrint.c: Likewise. * sysdeps/aarch64/fpu/s_lrintf.c: Likewise. * sysdeps/i386/fpu/s_atanl.c: Likewise. * sysdeps/i386/fpu/s_f32xaddf64.c: Likewise. * sysdeps/i386/fpu/s_f32xsubf64.c: Likewise. * sysdeps/i386/fpu/s_fdim.c: Likewise. * sysdeps/i386/fpu/s_logbl.c: Likewise. * sysdeps/i386/fpu/s_rintl.c: Likewise. * sysdeps/i386/fpu/s_significandl.c: Likewise. * sysdeps/ia64/fpu/s_matherrf.c: Likewise. * sysdeps/ia64/fpu/s_matherrl.c: Likewise. * sysdeps/ieee754/dbl-64/s_atan.c: Likewise. * sysdeps/ieee754/dbl-64/s_cbrt.c: Likewise. * sysdeps/ieee754/dbl-64/s_fma.c: Likewise. * sysdeps/ieee754/dbl-64/s_fmaf.c: Likewise. * sysdeps/ieee754/flt-32/s_cbrtf.c: Likewise. * sysdeps/ieee754/k_standardf.c: Likewise. * sysdeps/ieee754/k_standardl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_copysignl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_finitel.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_fpclassifyl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_isinfl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_isnanl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_signbitl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_cbrtl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fma.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fmal.c: Likewise. * sysdeps/ieee754/s_signgam.c: Likewise. * sysdeps/powerpc/power5+/fpu/s_modf.c: Likewise. * sysdeps/powerpc/power5+/fpu/s_modff.c: Likewise. * sysdeps/powerpc/power7/fpu/s_logbf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_ceil.c: Likewise. * sysdeps/riscv/rv64/rvd/s_floor.c: Likewise. * sysdeps/riscv/rv64/rvd/s_nearbyint.c: Likewise. * sysdeps/riscv/rv64/rvd/s_round.c: Likewise. * sysdeps/riscv/rv64/rvd/s_roundeven.c: Likewise. * sysdeps/riscv/rv64/rvd/s_trunc.c: Likewise. * sysdeps/riscv/rvd/s_finite.c: Likewise. * sysdeps/riscv/rvd/s_fmax.c: Likewise. * sysdeps/riscv/rvd/s_fmin.c: Likewise. * sysdeps/riscv/rvd/s_fpclassify.c: Likewise. * sysdeps/riscv/rvd/s_isinf.c: Likewise. * sysdeps/riscv/rvd/s_isnan.c: Likewise. * sysdeps/riscv/rvd/s_issignaling.c: Likewise. * sysdeps/riscv/rvf/fegetround.c: Likewise. * sysdeps/riscv/rvf/feholdexcpt.c: Likewise. * sysdeps/riscv/rvf/fesetenv.c: Likewise. * sysdeps/riscv/rvf/fesetround.c: Likewise. * sysdeps/riscv/rvf/feupdateenv.c: Likewise. * sysdeps/riscv/rvf/fgetexcptflg.c: Likewise. * sysdeps/riscv/rvf/ftestexcept.c: Likewise. * sysdeps/riscv/rvf/s_ceilf.c: Likewise. * sysdeps/riscv/rvf/s_finitef.c: Likewise. * sysdeps/riscv/rvf/s_floorf.c: Likewise. * sysdeps/riscv/rvf/s_fmaxf.c: Likewise. * sysdeps/riscv/rvf/s_fminf.c: Likewise. * sysdeps/riscv/rvf/s_fpclassifyf.c: Likewise. * sysdeps/riscv/rvf/s_isinff.c: Likewise. * sysdeps/riscv/rvf/s_isnanf.c: Likewise. * sysdeps/riscv/rvf/s_issignalingf.c: Likewise. * sysdeps/riscv/rvf/s_nearbyintf.c: Likewise. * sysdeps/riscv/rvf/s_roundevenf.c: Likewise. * sysdeps/riscv/rvf/s_roundf.c: Likewise. * sysdeps/riscv/rvf/s_truncf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_rint.c: Include <stdbool.h> instead of <math_private.h>. * sysdeps/riscv/rvf/s_rintf.c: Likewise.
2018-05-11Do not include math-barriers.h in math_private.h.Joseph Myers
This patch continues the math_private.h cleanup by stopping math_private.h from including math-barriers.h and making the users of the barrier macros include the latter header directly. No attempt is made to remove any math_private.h includes that are now unused, except in strtod_l.c where that is done to avoid line number changes in assertions, so that installed stripped shared libraries can be compared before and after the patch. (I think the floating-point environment support in math_private.h should also move out - some architectures already have fenv_private.h as an architecture-internal header included from their math_private.h - and after moving that out might be a better time to identify unused math_private.h includes.) Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/math_private.h: Do not include <math-barriers.h>. * stdlib/strtod_l.c: Include <math-barriers.h> instead of <math_private.h>. * math/fromfp.h: Include <math-barriers.h>. * math/math-narrow.h: Likewise. * math/s_nextafter.c: Likewise. * math/s_nexttowardf.c: Likewise. * sysdeps/aarch64/fpu/s_llrint.c: Likewise. * sysdeps/aarch64/fpu/s_llrintf.c: Likewise. * sysdeps/aarch64/fpu/s_lrint.c: Likewise. * sysdeps/aarch64/fpu/s_lrintf.c: Likewise. * sysdeps/i386/fpu/s_nextafterl.c: Likewise. * sysdeps/i386/fpu/s_nexttoward.c: Likewise. * sysdeps/i386/fpu/s_nexttowardf.c: Likewise. * sysdeps/ieee754/dbl-64/e_atan2.c: Likewise. * sysdeps/ieee754/dbl-64/e_atanh.c: Likewise. * sysdeps/ieee754/dbl-64/e_exp.c: Likewise. * sysdeps/ieee754/dbl-64/e_exp2.c: Likewise. * sysdeps/ieee754/dbl-64/e_j0.c: Likewise. * sysdeps/ieee754/dbl-64/e_sqrt.c: Likewise. * sysdeps/ieee754/dbl-64/s_expm1.c: Likewise. * sysdeps/ieee754/dbl-64/s_fma.c: Likewise. * sysdeps/ieee754/dbl-64/s_fmaf.c: Likewise. * sysdeps/ieee754/dbl-64/s_log1p.c: Likewise. * sysdeps/ieee754/dbl-64/s_nearbyint.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_nearbyint.c: Likewise. * sysdeps/ieee754/flt-32/e_atanhf.c: Likewise. * sysdeps/ieee754/flt-32/e_j0f.c: Likewise. * sysdeps/ieee754/flt-32/s_expm1f.c: Likewise. * sysdeps/ieee754/flt-32/s_log1pf.c: Likewise. * sysdeps/ieee754/flt-32/s_nearbyintf.c: Likewise. * sysdeps/ieee754/flt-32/s_nextafterf.c: Likewise. * sysdeps/ieee754/k_standardl.c: Likewise. * sysdeps/ieee754/ldbl-128/e_asinl.c: Likewise. * sysdeps/ieee754/ldbl-128/e_expl.c: Likewise. * sysdeps/ieee754/ldbl-128/e_powl.c: Likewise. * sysdeps/ieee754/ldbl-128/s_fmal.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nearbyintl.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nextafterl.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nexttoward.c: Likewise. * sysdeps/ieee754/ldbl-128/s_nexttowardf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/e_asinl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_fmal.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nexttoward.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nexttowardf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_rintl.c: Likewise. * sysdeps/ieee754/ldbl-96/e_atanhl.c: Likewise. * sysdeps/ieee754/ldbl-96/e_j0l.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fma.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fmal.c: Likewise. * sysdeps/ieee754/ldbl-96/s_nexttoward.c: Likewise. * sysdeps/ieee754/ldbl-96/s_nexttowardf.c: Likewise. * sysdeps/ieee754/ldbl-opt/s_nexttowardfd.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nextafterl.c: Likewise.

2014-02-11Relocate AArch64 from ports to libc.Marcus Shawcroft
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.
