From 783dd2d3af5aad76829e61ab5abeac5d466971f6 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 27 Oct 2015 21:47:22 +0000 Subject: Use -std=gnu11 instead of -std=gnu99. Now that GCC 4.7 or later is required to build glibc, this patch moves the build from using -std=gnu99 to -std=gnu11 (option added in 4.7). This allows use of C11 features from GCC's headers, such as new float.h macros and max_align_t. Tested for x86_64 and x86 (testsuite; installed stripped shared libraries are unchanged by the patch on x86_64, while I see some slight code reordering of no significance on x86). * Makeconfig (CFLAGS): Use -std=gnu11 instead of -std=gnu99. * Makefile ($(objpfx)c++-types-check.out): Filter out -std=gnu11 instead of -std=gnu99. * configure.ac (systemtap): Test with -std=gnu11 instead of -std=gnu99. * configure: Regenerated. * math/gen-auto-libm-tests.c: Use -std=gnu11 instead of -std=gnu99 in compilation command in comment. --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index 8ab0dbc..1d800e3 100644 --- a/Makefile +++ b/Makefile @@ -256,7 +256,7 @@ ifneq ($(CXX),no) vpath c++-types.data $(+sysdep_dirs) $(objpfx)c++-types-check.out: c++-types.data scripts/check-c++-types.sh - scripts/check-c++-types.sh $< $(CXX) $(filter-out -std=gnu99 $(+gccwarn-c),$(CFLAGS)) $(CPPFLAGS) > $@; \ + scripts/check-c++-types.sh $< $(CXX) $(filter-out -std=gnu11 $(+gccwarn-c),$(CFLAGS)) $(CPPFLAGS) > $@; \ $(evaluate-test) endif -- cgit v1.1
