From 547e970409b18021b63bfded0ffd852b8dcc4d3a Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 28 Nov 2016 23:12:49 +0000 Subject: Fix sysdeps/ia64/fpu/libm-symbols.h for inclusion in testcases. IA64 builds in math/ use "-include libm-symbols.h". This breaks the signgam tests, which rely on undefining _LIBC and feature test macros and defining _ISOMAC before including system headers to get them to provide only ISO C declarations (libm-symbols.h ending up indirectly including headers which result in this breaking); similarly, it breaks C++ tests as some headers included from libm-symbols.h are not ready for inclusion in C++ code. This patch disables the contents of libm-symbols.h if __STRICT_ANSI__ or __cplusplus are defined to avoid this problem (this header can only test symbols defined before the source file is processed, so can't test _ISOMAC because that's defined within the source file, after this header is included). Tested (compilation only) for ia64. * sysdeps/ia64/fpu/libm-symbols.h: Make contents conditional on [!__STRICT_ANSI__ && !__cplusplus]. --- ChangeLog | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index ec8b6d88ae..6d9b1629a6 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2016-11-28 Joseph Myers + + * sysdeps/ia64/fpu/libm-symbols.h: Make contents conditional on + [!__STRICT_ANSI__ && !__cplusplus]. + 2016-11-28 H.J.
