Date: Thu, 31 Oct 2013 15:59:58 +0000 From: Jamie Iles <jamie.iles@...cle.com> To: linux-kernel@...r.kernel.org Cc: Jamie Iles <jamie.iles@...cle.com>, Steven Rostedt <rostedt@...dmis.org> Subject: [PATCH] recordmcount.pl: add support for __fentry__ With gcc 4.6.0 the -mfentry feature places the function profiling call at the start of the function. When this is used, the call is to __fentry__ and not mcount. Based on 48bb5dc6cd9d30fe0d594947563da1f8bd9abada (ftrace: Make recordmcount.c handle __fentry__).
