Enumeration Type Documentation

ConstantEmissionKind

enum ConstantEmissionKind

Can we constant-emit a load of a reference to a variable of the given type?

This is different from predicates like Decl::mightBeUsableInConstantExpressions because we do want it to apply in situations that don't necessarily satisfy the language's rules for this (e.g. C++'s ODR-use rules). For example, we want to able to do this with const float variables even if those variables aren't marked 'constexpr'.

convertSizedByBoundToElementCount()

llvm::Value * convertSizedByBoundToElementCount ( CodeGenFunction & CGF, llvm::Value * BoundsVal, QualType PointeeTy, bool CountSigned )

static

Convert a '__sized_by' byte-count bound to an element-count bound so it can be compared against an element index.

BoundsVal is the loaded byte count and PointeeTy is the pointer's pointee type. Returns BoundsVal unchanged when no scaling is needed, otherwise returns a new llvm::Value* that is element count.
