From aa9fa1e22a61f60c51ef7886cb297bfbad3cc305 Mon Sep 17 00:00:00 2001 From: Tristan Gingold Date: Fri, 21 Mar 2014 09:25:05 +0100 Subject: [PATCH] Fix stack offset in Mach-O output for -P compact_unwind. Minor fix in compact unwind output: to be more readable, the stack offset for indirect compact unwind entries are mutiplied by its factor (4 or 8). binutils/ * od-macho.c (dump_unwind_encoding_x86): Set the factor. (dump_exe_compact_unwind): Change the condition.
