Detailed Description

ABIArgInfo - Helper class to encapsulate information about how a specific C type should be passed to or returned from a function.

Member Enumeration Documentation

enum clang::ABIArgInfo::Kind

Enumerator:

Direct	Direct - Pass the argument directly using the normal converted LLVM type, or by coercing to another specified type stored in 'CoerceToType'). If an offset is specified (in UIntData), then the argument passed is offset by some number of bytes in the memory representation. A dummy argument is emitted before the real argument if the specified type stored in "PaddingType" is not zero.
Extend	Extend - Valid only for integer argument types. Same as 'direct' but also emit a zero/sign extension attribute.
Indirect	Indirect - Pass the argument indirectly via a hidden pointer with the specified alignment (0 indicates default alignment).
Ignore	Ignore - Ignore the argument (treat as void). Useful for void and empty structs.
Expand	Expand - Only valid for aggregate argument types. The structure should be expanded into consecutive arguments for its constituent fields. Currently expand is only allowed on structures whose fields are all scalar types or are themselves expandable types.
