Struct rustc_codegen_llvm::abi::ArgAttributes

pub struct ArgAttributes {
    pub regular: ArgAttribute,
    pub arg_ext: ArgExtension,
    pub pointee_size: Size,
    pub pointee_align: Option<Align>,
}

A compact representation of LLVM attributes (at least those relevant for this module) that can be manipulated without interacting with LLVM’s Attribute machinery.

Fields

regular: ArgAttribute

arg_ext: ArgExtension

pointee_size: Size

The minimum size of the pointee, guaranteed to be valid for the duration of the whole call (corresponding to LLVM’s dereferenceable and dereferenceable_or_null attributes).

pointee_align: Option<Align>

Trait Implementations

    llfn: &Value
)

fn apply_attrs_to_callsite(
    &self,

    callsite: &Value
)

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
