From: Arjan van de Ven Date: Sat, 7 Feb 2009 20:23:37 +0000 (-0800) Subject: x86: don't pretend that non-framepointer stack traces are reliable X-Git-Tag: v2.6.31-rc1~383^2~508^2~2^5 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=2c344e9d6e1938fdf15e93c56d6fe42f8410e9d3;p=~emulex%2Finfiniband.git x86: don't pretend that non-framepointer stack traces are reliable Without frame pointers enabled, the x86 stack traces should not pretend to be reliable; instead they should just be what they are: unreliable. The effect of this is that they have a '?' printed in the stacktrace, to warn the reader that these entries are guesses rather than known based on more reliable information.
