From 818331303bc7cb914351c992d3da00aae957eba7 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 5 Oct 2009 23:35:03 -0300 Subject: [PATCH] perf tools: elf_sym__is_function() should accept "zero" sized functions MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Asm routines that end up having size equal to zero are not really zero sized, and as now we do kernel_maps__fixup_sym_end, at least for kernel routines this gets fixed. A similar fixup needs to be done for the userspace bits as well, but as this fixup started only because in /proc/kallsyms we don't have the end address nor the function size, it appeared here first.
