This file defines the SmallPtrSet class.

A cache of @llvm.assume calls within a function.

A parsed version of the target data layout string in and methods for querying it.

Concrete subclass of DominatorTreeBase that is used to compute a normal dominator tree.

SmallPtrSet - This class implements a set which is optimized for holding SmallSize or less elements.

Provides information about what library functions are available for the current target.

LLVM Value Representation.

This is an optimization pass for GlobalISel generic memory operations.

bool isa(const From &Val)

isa - Return true if the parameter to the template is an instance of one of the template type argu...

DWARFExpression::Operation Op

decltype(auto) cast(const From &Val)

cast - Return the argument parameter cast to the specified type.

Evaluate query assuming this condition holds.
