3.18.1. AArch64 Options
3.18.1 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 pointers are 32 bits, and ‘lp64’ for SysV-like data model where int is 32 bits, but long int and pointers are 64 bits.
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.
-mbig-endian-
Generate big-endian code. This is the default when GCC is configured for an ‘aarch64_be-*-*’ target.
-mgeneral-regs-only
