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.

arc600_norm

Assemble for ARC 600 with norm instructions.

arc600_mul64

Assemble for ARC 600 with mul64 instructions.

arc600_mul32x16

Assemble for ARC 600 with mul32x16 instructions.

arc601 ¶

Assemble for ARC 601. Alias: -mARC601.

arc601_norm

Assemble for ARC 601 with norm instructions.

arc601_mul64

Assemble for ARC 601 with mul64 instructions.

arc601_mul32x16

Assemble for ARC 601 with mul32x16 instructions.

arc700 ¶

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

arcem ¶

Assemble for ARC EM. Aliases: -mEM

em

Assemble for ARC EM, identical as arcem variant.

em4

Assemble for ARC EM with code-density instructions.

em4_dmips

Assemble for ARC EM with code-density instructions.

em4_fpus

Assemble for ARC EM with code-density instructions.

em4_fpuda

Assemble for ARC EM with code-density, and double-precision assist instructions.

quarkse_em

Assemble for QuarkSE-EM cpu.

archs ¶

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

hs

Assemble for ARC HS.

hs34

Assemble for ARC HS34.

hs38

Assemble for ARC HS38.

hs38_linux

Assemble for ARC HS38 with floating point support on.

nps400 ¶

Assemble for ARC 700 with NPS-400 extended instructions.

Note: the .cpu directive (see ARC Machine Directives) 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.

-mrelax ¶

Enable support for assembly-time relaxation. The assembler will replace a longer version of an instruction with a shorter one, whenever it is possible.

-mnps400 ¶

Enable support for NPS-400 extended instructions.

-mspfp ¶

Enable support for single-precision floating point instructions.

-mdpfp ¶

Enable support for double-precision floating point instructions.

-mfpuda ¶

Enable support for double-precision assist floating point instructions. Only valid for ARC EM processors.
