aarch64: Implement math acceleration via builtins
This patch converts asm statements into builtins for AArch64. 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.
