From 1ac9c1cf87216bf9f8ac4f7c9754d025d9f2c4ae Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Wed, 11 Dec 2019 15:09:22 +0100 Subject: Use GCC builtins for trunc functions if desired. This patch is using the corresponding GCC builtin for truncf, trunc, truncl and truncf128 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.
