Summary: LICM doesn't preserve scalar-evolution correctly
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: new bugs
AssignedTo: unassignedbugs at nondot.org
ReportedBy: sharparrow1 at yahoo.com
CC: llvmbugs at cs.uiuc.edu
Per summary; moving an instruction out of a loop while preserving SCEV requires
a call to ScalarEvolution::forgetValue(), but LICM doesn't call it at the
moment. Noting here so I don't forget about it.
