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.
