3.17.1 AArch64 Options

These options are defined for AArch64 implementations:

-mabi=name

    Generate code for the specified data model. Permissible values are
    ‘ilp32’ for SysV-like data model where int, long int and pointer
    are 32-bit, and ‘lp64’ for SysV-like data model where int is
    32-bit, but long int and pointer are 64-bit.

    The default depends on the specific target configuration. Note
    that the LP64 and ILP32 ABIs are not link-compatible; you must
    compile your entire program with the same ABI, and link with a
    compatible set of libraries.
