From 4d7d8c82c181711d28c8336108330a9121f5ef07 Mon Sep 17 00:00:00 2001 From: Chuck Ebbert <76306.1226@compuserve.com> Date: Thu, 23 Mar 2006 02:59:30 -0800 Subject: [PATCH] i386: multi-column stack backtraces Print stack backtraces in multiple columns, saving screen space. Number of columns is configurable and defaults to one so behavior is backwards-compatible. Also removes the brackets around addresses when printing more that one entry per line so they print as:
instead of: [
] This helps multiple entries fit better on one line. Original idea by Dave Jones, taken from x86_64.
