commit 2b48ff1b0c1083ea8f010867b252547cbaa5cb75
Author: Stefan Liebler via Libc-alpha <libc-alpha@sourceware.org>
Date:   Fri Apr 17 08:49:51 2020 -0300

    Use libc_fe* macros in ldbl-128/s_nearbyintl.c
    
    The calls to feholdexcept and fesetenv are replaced
    by the libc_fe* macros as it is also done in nearbyintf
    and nearbyint.
