[commit] r6065 - trunk/util/lint

[repository service]

Author: oxygene
Date: Fri Nov 12 10:46:30 2010
New Revision: 6065
URL: https://tracker.coreboot.org/trac/coreboot/changeset/6065

Log:
Consensus seems that this is wanted, integrated into the tree somehow.
This isn't hooked up anywhere, so won't affect anything, except for
developers trying to remove configuration #defines.

+# Remove C and C++ comments, by Brian Hiles ([e-mail])

+# Sped up (and bugfixed to some extent) by Paolo Bonzini ([e-mail])
+# Works its way through the line, copying to hold space the text up to the
+# first special character (/, ", ').  The original version went exactly a
+# character at a time, hence the greater speed of this one.  But the concept
+# and especially the trick of building the line in hold space are entirely
+# merit of Brian.
