9.3.1 Options

The following options control the type of CPU for which code is assembled, and generic constraints on the code generated:

-mcpu=cpu

Set architecture type and register usage for cpu. There are also shortcut alias options available for backward compatibility and convenience. Supported values for cpu are

arc600

Assemble for ARC 600. Aliases: -mA6, -mARC600.

arc601

Assemble for ARC 601. Alias: -mARC601.

arc700

Assemble for ARC 700. Aliases: -mA7, -mARC700.

arcem

Assemble for ARC EM. Aliases: -mEM

archs

Assemble for ARC HS. Aliases: -mHS, -mav2hs.

Note: the .cpu directive can to be used to select a core variant from within assembly code.

-EB

This option specifies that the output generated by the assembler should be marked as being encoded for a big-endian processor.

-EL

This option specifies that the output generated by the assembler should be marked as being encoded for a little-endian processor - this is the default.

-mcode-density

This option turns on Code Density instructions. Only valid for ARC EM processors.
