Functions  
static LogicalResult  staticallyNonNegative (DataFlowSolver &solver, Value v) 
Succeeds when a value is statically nonnegative in that it has a lower bound on its value (if it is treated as signed) and that bound is nonnegative. More...  
static LogicalResult  staticallyNonNegative (DataFlowSolver &solver, Operation *op) 
Succeeds if an op can be converted to its unsigned equivalent without changing its semantics. More...  
static LogicalResult  isCmpIConvertable (DataFlowSolver &solver, CmpIOp op) 
Succeeds when the comparison predicate is a signed operation and all the operands are nonnegative, indicating that the cmpi operation op can have its predicate changed to an unsigned equivalent. More...  
static CmpIPredicate  toUnsignedPred (CmpIPredicate pred) 
Return the unsigned equivalent of a signed comparison predicate, or the predicate itself if there is none. More...

static 
Succeeds when the comparison predicate is a signed operation and all the operands are nonnegative, indicating that the cmpi operation op
can have its predicate changed to an unsigned equivalent.
Definition at line 55 of file UnsignedWhenEquivalent.cpp.

static 
Succeeds if an op can be converted to its unsigned equivalent without changing its semantics.
This is the case when none of its openands or results can be below 0 when analyzed from a signed perspective.

Succeeds when a value is statically nonnegative in that it has a lower bound on its value (if it is treated as signed) and that bound is nonnegative.
