+
+ stdlib: support non-GCC __attribute__
+
+ Fix a serious and tricky problem encountered when attempting to
+ add the getloadavg module to Emacs. Emacs worked fine on RHEL
+ 5.5, but it crashed due to memory corruption on Solaris 10 with
+ Sun C 5.11. Emacs normally ORs 3-bit tags into their low-order
+ bits that are otherwise zero. This tagging is optional inside
+ Emacs but is preferred and is used when __attribute__ ((__aligned
+ (8))) works, as it does with both recent-enough GCC and with Sun C
+ 5.11. However, Sun C 5.11 is not GCC and does not #define
+ __GNUC__ and __GNUC_MINOR__.
+
+ When I added the getloadavg module to Emacs, it brought in
+ stdlib.in.h, which contained this fragment:
+
+ #ifndef __attribute__
+ # if __GNUC__ < 2 || (__GNUC__ == 2 && __GNUC_MINOR__ < 8)
+ # define __attribute__(Spec) /* empty */
+ # endif
+ #endif
+
+ When files that include <stdlib.h> were compiled with Sun C 5.11,
+ the above code disabled __attribute__ ((__aligned (8))), which
+ caused variables to not be properly aligned, which eventually led
+ to the pointer corruption mentioned above. (This was a bit hard
+ to diagnose, unfortunately.)
+
+ Several "#define __attribute__(X) /* empty */" code snippets need
+ to be eradicated from Gnulib to work with non-GCC compilers that
+ support __attribute__. The Autoconf way to do this is to test for
+ each kind of attribute that we want support for, and selectively
+ enable that in source code.
+
+ Fix this problem just for stdlib.h, by adding a test for the
+ __noreturn__ attribute, and change stdlib.in.h to use that test
+ when needed. This technique can be easily generalized to the
+ other *.in.h files and attributes, and a similar technique can be
+ used for *.h and *.c files. This patch is enough to solve the
+ problem for Emacs + getloadavg, and I thought I'd publish it for
+ feedback before undertaking further, similar fixes in other
+ modules.
+
+ This patch does not arrange to #define HAVE_ATTRIBUTE_NORETURN
+ because it's not needed for stdlib.h. It merely substitutes the
+ value directly into stdlib.h. We may well need to #define it, or
+ similar symbols, for other modules, but it's nice to also have an
+ option to not #define it for applications like Emacs that do not
+ need it.
+

+ (_GL_ATTRIBUTE_NORETURN): New macro, which in stdlib.h needs to
+ be defined only if the _Exit module is also used.
