From 2366bf60c667d968c88e7bcec2eb9e2b84d0172d Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Sat, 19 Oct 2019 07:44:49 +0000 Subject: [PATCH] [Darwin, testsuite] Fix Wnonnull on Darwin. Darwin does not mark entries in string.h with nonnull attributes so the test fails. Since the purpose of the test is to check that the warnings are issued for an inlined function, not that the target headers are marked up, we can provide marked up headers for Darwin. gcc/testsuite/ChangeLog: 2019-10-19 Iain Sandoe * gcc.dg/Wnonnull.c: Add attributed function declarations for memcpy and strlen for Darwin.
