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.
