From: Chris Wilson Date: Fri, 2 Oct 2009 18:46:03 +0000 (+0100) Subject: intel: Assert that relocation offsets are within the target X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=470ec8d42e1941c0ad773084693323f96a83e64d;p=mesa.git intel: Assert that relocation offsets are within the target This should catch the common programming error where we attempt to emit a relocation to beyond the end of the target buffer.
