* ubsan shift fixesGravatar caryclark2015-12-09
| | | | | | | | | | | Use an inline function that does a normal shift. When built for the sanitizer, add casts so that the shift is unsigned. Also make a few fixes to do unsigned shifts or avoid the shift altogether; and add an argument spec to some macros.
