Module rustc_codegen_llvm::abi
source · Structs
Information about how to pass an argument to,
or return a value from, a function, under some ABI.
A compact representation of LLVM attributes (at least those relevant for this module)
that can be manipulated without interacting with LLVM’s Attribute machinery.
Metadata describing how the arguments to a native function
should be passed in order to respect the native ABI.
Error from the
homogeneous_aggregate test function, indicating
there are distinct leaf fields passed in different ways,
or this is uninhabited.An argument passed entirely registers with the
same kind (e.g., HFA / HVA on PPC64 and AArch64).
Enums
Error produced by attempting to adjust a
FnAbi, for a “foreign” ABI.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.
Return value from the
homogeneous_aggregate test function.Constants
The first half of a fat pointer.
The second half of a fat pointer.
