+*Notice*: GCC 7.1 ABI change for arm*-*-* targets, and note for aarch64*-*-* targets
+
+From GCC 7.1 release notes:
+
+_On ARM targets (arm*-*-*), a bug introduced in GCC 5 that affects conformance to the procedure call standard (AAPCS) has been fixed. The bug affects some C++ code where class objects are passed by value to functions and could result in incorrect or inconsistent code being generated. This is an ABI change. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected._

+
+{{ urlind(8,"https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728") }}
+        {%- call format("para") %}
+GCC 5 and GCC 6 releases will continue to be affected by the ABI bug, since changing ABI in these releases is not practical.  A warning enabled by -Wpsabi option was added to GCC 5 and GCC 6 toolchains to diagnose codebases that might be affected by the ABI bug.
+
+Additionally, this same bug was present in AArch64 backend in development versions of GCC 7.  There was no releases of GCC with this bug present in AArch64 backend, therefore the release notes does not mention this.  However, be advised that any code bases built with development versions of GCC 7 need to be recompiled with released version of GCC 7 to conform to ABI.
