[PATCH 1/2] IBM Z: Configure excess precision for float at compile-time

2020-11-25 Thread Marius Hillenbrand via Gcc-patches
Historically, float_t has been defined as double on s390 and gcc would emit double precision insns for evaluating float expressions when in standard-compliant mode. Configure that behavior at compile-time as prep for changes in glibc: When glibc ties float_t to double, keep the old behavior; when
