From 264b817b8eb1bf626ade1db6c200f2fa91358331 Mon Sep 17 00:00:00 2001 From: Pieter du Preez Date: Sun, 14 Feb 2016 11:12:06 +0100 Subject: Define the newlib version macros in one place: _newlib_version.h. Currently, the newlib version information needs to be updated in two places: - newlib/acinclude.m4 - newlib/libc/include/sys/features.h The goal of this patch is to: - supply a single location for defining the newlib version information: newlib/acinclude.m4 - define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__ This is in line with what gcc does for its version macros. See: https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__ and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h, to the newly generated newlib/_newlib_version.h file. Additionally, the __NEWLIB_PATCHLEVEL__ macro was created, for completeness. In order to stay backwards compatible, newlib/_newlib_version.h gets included by newlib/newlib.h and newlib/libc/include/sys/features.h. Note: This patch does _not_ include the modifications to the following files, as these should all be generated any way. *Makefile.in, *aclocal.m4, *configure stamp-* files Signed-off-by: Pieter du Preez --- newlib/_newlib_version.hin | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 newlib/_newlib_version.hin (limited to 'newlib/_newlib_version.hin') diff --git a/newlib/_newlib_version.hin b/newlib/_newlib_version.hin new file mode 100644 index 000000000..03d4e3d47 --- /dev/null +++ b/newlib/_newlib_version.hin @@ -0,0 +1,11 @@ +/* Version macros for internal and downstream use. */ +#ifndef _NEWLIB_VERSION_H__ +#define _NEWLIB_VERSION_H__ 1 + +#undef _NEWLIB_VERSION +#undef __NEWLIB__ +#undef __NEWLIB_MINOR__ +#undef __NEWLIB_PATCHLEVEL__ + +#endif /* !_NEWLIB_VERSION_H__ */ + -- cgit v1.2.3
