8.1.1 Options

The ARC chip family includes several successive levels (or other variants) of chip, using the same core instruction set, but including a few additional instructions at each level.

By default, as assumes the core instruction set (ARC base). The .cpu pseudo-op is intended to be used to select the variant.

-mbig-endian

-mlittle-endian

Any ARC configuration of as can select big-endian or little-endian output at run time (unlike most other GNU development tools, which must be configured for one or the other). Use `-mbig-endian' to select big-endian output, and `-mlittle-endian' for little-endian.
