Function const_all_ones

Source 
pub fn const_all_ones(ty: &TypeRef) -> ValueRef
Expand description

Obtain a constant value referring to the instance of a type consisting of all ones.

This is only valid for integer types.

§Details

Creates a constant value with all bits set to one for the specified type.

This function wraps the LLVMConstAllOnes function from the LLVM core library. It generates a constant value for the specified type (ty) where all the bits are set to one. This is often used to represent a value where all bits are enabled, such as -1 for signed integers or the maximum possible value for unsigned integers.

§Parameters

  • ty: A reference to the type (TypeRef) for which the all-ones value should be created. This type determines the size and nature of the value (e.g., integer, vector).

§Returns

Returns an instance of ValueRef, which encapsulates the constant all-ones value for the specified type.
