From 4e31050f482c02c822b150d71cf1ea5be7c9d6e4 Mon Sep 17 00:00:00 2001 From: Vinson Lee Date: Mon, 9 Feb 2015 16:29:37 -0800 Subject: [PATCH] perf symbols: Define STT_GNU_IFUNC for glibc 2.9 and older. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The token STT_GNU_IFUNC is not available with glibc 2.9 and older. Define this token if it is not already defined. This patch fixes this build errors with older versions of glibc.
