+Subject: [PATCH] Fix: use __noreturn__ for C11-compatibility
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The noreturn convenience macro provided by stdnoreturn.h might get
+included before urcu headers, use __noreturn__ for better compatibility
+with code using <stdnoreturn.h> header.

+Subject: [PATCH] fix: warning 'noreturn' function does return on ppc
+
+On a ppc64 system with gcc 9.5.0 I get the following error when building
+with -O0 :
+
+/usr/include/urcu/uatomic/generic.h: In function 'void _uatomic_link_error()':
+/usr/include/urcu/uatomic/generic.h:53:1: warning: 'noreturn' function does return
+   53 | }
+      | ^
+
+Split the inline function in 2 variants and apply the noreturn attribute
+only on the builtin_trap one.
