Fix the following issues with built-in function use in sysdeps/ieee754/ldbl-128 and sysdeps/ieee754/float128: * fabsl used __builtin_fabsf128 unconditionally, breaking the build with GCC 6 for several architectures; it should use __builtin_fabsl with an appropriate redirection in float128_private.h. (I'm not particularly concerned with building glibc with GCC 6; rather, I want to be able to run the tgmath.h tests with GCC 6, which is a significantly different case for tgmath.h compared to GCC 7 and later because of the lack of _FloatN / _FloatNx support in the compiler, and at present running the tests with a compiler means building glibc with that compiler.) * Some (conditional) uses of built-in functions had been added to ldbl-128 without appropriate float128_private.h remapping (there was remapping for the macros controlling whether the built-in functions are used, just not for the functions themselves). * s_llrintl.c called __builtin_round not __builtin_llrintl, which is obviously wrong. Tested with build-many-glibcs.py for aarch64-linux-gnu, GCC 6 (where it fixes the glibc build) and GCC 12, and with the glibc testsuite for x86_64. |
