Date: Fri, 21 Mar 2014 23:42:54 -0700 From: behanw@...verseincode.com To: linux@....linux.org.uk Cc: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, dwmw2@...radead.org, pageexec@...email.hu, Mark Charlebois <charlebm@...il.com>, Behan Webster <behanw@...verseincode.com> Subject: [PATCH] unwind_support From: Mark Charlebois <charlebm@...il.com> Patch to prevent warning of a buggy compiler when using clang and the ARM_UNWIND option. Clang defines (at least on the current trunk) GNUC, GNUC_MINOR, and GNUC_PATCHLEVEL to 4, 2, and 1 respectively. This version of GCC gets flagged as buggy, but it isn't actually an issue with clang so the patch will do what it did before unless clang is defined and then it will not report the GCC version as an issue.
