Joseph Myers 81dca813cc Use copysign functions not __copysign functions in glibc libm. ... 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 __copysign functions to call the corresponding copysign names instead, with asm redirection to __copysign when the calls are not inlined (all cases are inlined except for IBM long double for powerpc soft-float / e500v1). This eliminates the need for an inline function defining __copysign in terms of __builtin_copysign. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (MATH_REDIRECT_BINARY_ARGS): New macro. [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (copysign): Redirect using MATH_REDIRECT. * sysdeps/alpha/fpu/s_copysign.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/alpha/fpu/s_copysignf.c: Likewise. * sysdeps/ieee754/dbl-64/s_copysign.c: Likewise. * sysdeps/ieee754/float128/s_copysignf128.c: Likewise. * sysdeps/ieee754/flt-32/s_copysignf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_copysignl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_copysignl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_copysignl.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/riscv/rvd/s_copysign.c: Likewise. * sysdeps/riscv/rvf/s_copysignf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysign.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/generic/math_private_calls.h [!__MATH_DECLARING_LONG_DOUBLE || !NO_LONG_DOUBLE] (__copysign): Do not declare and define as an inline function. * math/divtc3.c (__divtc3): Use copysign functions instead of __copysign variants. * math/multc3.c (__multc3): Likewise. * sysdeps/generic/math-type-macros.h (M_COPYSIGN): Likewise. * sysdeps/ieee754/dbl-64/e_atan2.c (signArctan2): Likewise. * sysdeps/ieee754/dbl-64/e_atanh.c (__ieee754_atanh): Likewise. * sysdeps/ieee754/dbl-64/e_gamma_r.c (__ieee754_gamma_r): Likewise. * sysdeps/ieee754/dbl-64/e_jn.c (__ieee754_jn): Likewise.
