Macro Definition Documentation

#define ABI_BIGARG_ALIGN 0x00000004

use natural type alignment for argument if the alignment exceeds native word size.

(e.g. __int64 argument should be 8byte aligned on some 32bit platforms)

#define ABI_HUGEARG_ALIGN 0x00000200

use natural type alignment for an argument even if its alignment exceeds double native word size (the default is to use double word max).

e.g. if this bit is set, __int128 has 16-byte alignment. this bit is not used by ida yet
