From a2a9b004297b777758420c952cb6eea5985d37fe Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Wed, 11 Dec 2019 15:09:20 +0100 Subject: Use GCC builtins for rint functions if desired. This patch is using the corresponding GCC builtin for rintf, rint, rintl and rintf128 if the USE_FUNCTION_BUILTIN macros are defined to one in math-use-builtins.h. This is the case for s390 if build with at least --march=z196 --mzarch. Otherwise the generic implementation is used. The code of the generic implementation is not changed.
