From e403e433c1a30568a019cac9ba7301f8d5d7a382 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Mon, 9 Aug 2010 16:43:53 +0200 Subject: elf: Calculate symbol size if needed Symbols with a size of 0 are unusable for the disassembler. Example: While running an arm linux kernel, no symbolic names are used in qemu.log when the cpu is executing an assembler function. Assume that the size of such symbols is the difference to the next symbol value.
