* Update copyright dates with scripts/update-copyrightsPaul Eggert2022-01-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

* Use libm_alias_float for aarch64.Joseph Myers2017-11-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes aarch64 libm function implementations use libm_alias_float to define function aliases. Tested with build-many-glibcs.py for aarch64-linux-gnu that installed stripped shared libraries are unchanged by the patch. * sysdeps/aarch64/fpu/s_ceilf.c: Include <libm-alias-float.h>.

As an example for the file sysdeps/aarch64/fpu/s_ceil.c, we convert the function from double __ceil (double x) { double result; asm ("frintp\t%d0, %d1" : "=w" (result) : "w" (x) ); return result; } into double __ceil (double x) { return __builtin_ceil (x); } Tested on aarch64-linux-gnu with gcc-4.9.4 and gcc-6. * sysdeps/aarch64/fpu/e_sqrt.c (ieee754_sqrt): Replace asm statements with __builtin_sqrt. * sysdeps/aarch64/fpu/e_sqrtf.c (ieee754_sqrtf): Replace asm statements with __builtin_sqrtf. * sysdeps/aarch64/fpu/s_ceil.c (__ceil): Replace asm statements with __builtin_ceil. * sysdeps/aarch64/fpu/s_ceilf.c (__ceilf): Replace asm statements with __builtin_ceilf. * sysdeps/aarch64/fpu/s_floor.c (__floor): Replace asm statements with __builtin_floor. * sysdeps/aarch64/fpu/s_floorf.c (__floorf): Replace asm statements with __builtin_floorf. * sysdeps/aarch64/fpu/s_fma.c (__fma): Replace asm statements with __builtin_fma. * sysdeps/aarch64/fpu/s_fmaf.c (__fmaf): Replace asm statements with __builtin_fmaf. * sysdeps/aarch64/fpu/s_fmax.c (__fmax): Replace asm statements with __builtin_fmax. * sysdeps/aarch64/fpu/s_fmaxf.c (__fmaxf): Replace asm statements with __builtin_fmaxf. * sysdeps/aarch64/fpu/s_fmin.c (__fmin): Replace asm statements with __builtin_fmin. * sysdeps/aarch64/fpu/s_fminf.c (__fminf): Replace asm statements with __builtin_fminf. * sysdeps/aarch64/fpu/s_frint.c: Delete file. * sysdeps/aarch64/fpu/s_frintf.c: Delete file. * sysdeps/aarch64/fpu/s_llrint.c (__llrint): Replace asm statements with builtin_rint and conversion to int. * sysdeps/aarch64/fpu/s_llrintf.c (__llrintf): Likewise. * sysdeps/aarch64/fpu/s_llround.c (__llround): Replace asm statements with builtin_llround. * sysdeps/aarch64/fpu/s_llroundf.c (__llroundf): Likewise. * sysdeps/aarch64/fpu/s_lrint.c (__lrint): Replace asm statements with builtin_rint and conversion to long int. * sysdeps/aarch64/fpu/s_lrintf.c (__lrintf): Likewise. * sysdeps/aarch64/fpu/s_lround.c (__lround): Replace asm statements with builtin_lround. * sysdeps/aarch64/fpu/s_lroundf.c (__lroundf): Replace asm statements with builtin_lroundf. * sysdeps/aarch64/fpu/s_nearbyint.c (__nearbyint): Replace asm statements with __builtin_nearbyint. * sysdeps/aarch64/fpu/s_nearbyintf.c (__nearbyintf): Replace asm statements with __builtin_nearbyintf. * sysdeps/aarch64/fpu/s_rint.c (__rint): Replace asm statements with __builtin_rint. * sysdeps/aarch64/fpu/s_rintf.c (__rintf): Replace asm statements with __builtin_rintf. * sysdeps/aarch64/fpu/s_round.c (__round): Replace asm statements with __builtin_round. * sysdeps/aarch64/fpu/s_roundf.c (__roundf): Replace asm statements with __builtin_roundf. * sysdeps/aarch64/fpu/s_trunc.c (__trunc): Replace asm statements with __builtin_trunc. * sysdeps/aarch64/fpu/s_truncf.c (__truncf): Replace asm statements with __builtin_truncf. * sysdeps/aarch64/fpu/Makefile: Build e_sqrt[f].c with -fno-math-errno.

* Relocate AArch64 from ports to libc.Marcus Shawcroft2014-02-111-0/+23
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.
