The Xtensa ABI implementation

Structs

ArgAbi

Information about how to pass an argument to, or return a value from, a function, under some ABI.

ArgAttributes

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

CastTarget

Describes the type used for PassMode::Cast.

FnAbi

Metadata describing how the arguments to a native function should be passed in order to respect the native ABI.

Uniform

An argument passed entirely registers with the same kind (e.g., HFA / HVA on PPC64 and AArch64).

Enums

ArgExtension

Sometimes an ABI requires small integers to be extended to a full or partial register. This enum defines if this extension should be zero-extension or sign-extension when necessary. When it is not necessary to extend the argument, this enum is ignored.

IndirectMode

Different modes in which indirect arguments can be passed.

PassMode

Functions

fields_are_noundef 🔒

Returns true if the fields of layout contiguously cover bytes 0..layout.size with no padding gaps and each field is recursively layout_is_noundef.

layout_is_noundef 🔒

Determines whether layout contains no uninit bytes (no padding, no unions), using only the computed layout.
