Subject: [RFC PATCH 02/30 v3] Annotate core code that should not be traced
Date: Tue, 15 Jan 2008 15:49:09 -0500 [thread overview]
Message-ID: <20080115205021.610690490@goodmis.org> (raw)
In-Reply-To: 20080115204907.838227723@goodmis.org
[-- Attachment #1: mcount-annotate-generic-code.patch --]
[-- Type: text/plain, Size: 922 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.
