From 35555851d700a267cca5070e65670c5a5f352d95 Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Wed, 10 Oct 2018 17:53:55 +0200 Subject: [PATCH] newlib: strtold: use __builtin_nanl to avoid libm dependency Commit 6c212a8b7873703c4f98c6b68579b234918be83a ("Fix strtod ("nan") and strtold ("nan") returns wrong negative NaN") introduced an unconditional dependency to nanl and, in turn, to libm. Rather than including nanl in libc as well, just call __builtin_nanl from here. Requires GCC 3.3 or later.
