Add in a --dorandomvars which sets local variables to values other than 0 to try and find bugs which depend on them being initalized to 0. Also turn off the other transformations by default (use --dokerneltrace or --donullint) Go get em Chad. 2005-05-27 17:46:23 -04:00			$OpenBSD: patch-src_cilutil_ml,v 1.3 2005/05/27 21:46:23 avsm Exp $
Add a 'kernel function call tracer' to automatically insert a call to log() to certain functions in the kernel to help debugging. An example use when building a kernel would be: $ make CC='/usr/local/bin/cilly --trace-regexp=^cache_ --trace-level=0' to instrument all functions starting with cache_* to notify syslog at emergency log level. The output also includes the contents of any char/int/long arguments (pointers and structs not followed yet, too verbose). A full kernel build doesnt quite work with CIL yet so use selectively. 2005-05-27 02:31:52 -04:00			`--- src/cilutil.ml.orig Mon Jan 31 09:56:18 2005`
