History
Arnaud A. de Grandmaison 35763b1ee7 InstCombine: simplify comparisons to zero of (shl %x, Cst) or (mul %x, Cst) 
This simplification happens at 2 places :
 - using the nsw attribute when the shl / mul is used by a sign test
 - when the shl / mul is compared for (in)equality to zero

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
