Options

The SPARC 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 (SPARC v6), but "bumps" the architecture level as needed: it switches to successively higher architectures as it encounters instructions that only exist in the higher levels.

-Av6 | -Av7 | -Av8 | -Av9 | -Asparclite

Use one of the `-A' options to select one of the SPARC architectures explicitly. If you select an architecture explicitly, as reports a fatal error if it encounters an instruction or feature requiring a higher level.

-bump

Permit the assembler to "bump" the architecture level as required, but warn whenever it is necessary to switch to another level.
