Subject: [PATCH 03/22 -v7] Annotate core code that should not be traced
Date: Tue, 29 Jan 2008 22:15:24 -0500 [thread overview]
Message-ID: <20080130031840.503123953@goodmis.org> (raw)
In-Reply-To: <20080130031521.258552785@goodmis.org>
[-- Attachment #1: mcount-annotate-generic-code.patch --]
[-- Type: text/plain, Size: 919 bytes --]
Mark with "notrace" functions in core code that should not be
traced. The "notrace" attribute will prevent gcc from adding
a call to mcount on the annotated funtions.
