Chapter 2. Overview

11

 m68hc11 |  m68hc12 |  m68hcs12

Specify what processor is the target. The default is defined by the configuration option when

building the assembler.

 mshort

Specify to use the 16 bit integer ABI.

 mlong

Specify to use the 32 bit integer ABI.

 mshort double

Specify to use the 32 bit double ABI.

 mlong double

Specify to use the 64 bit double ABI.

 force long branchs

Relative branches are turned into absolute ones. This concerns conditional branches, uncondi 

tional branches and branches to a sub routine.

 S |  short branchs

Do not turn relative branchs into absolute ones when the offset is out of range.

 strict direct mode

Do not turn the direct addressing mode into extended addressing mode when the instruction does

not support direct addressing mode.

 print insn syntax

Print the syntax of instruction in case of error.

 print opcodes

print the list of instructions with syntax and then exit.

 generate example

print an example of instruction for each possible instruction and then exit. This option is only

useful for testing

as

.

The following options are available when

as

is configured for the SPARC architecture:

 Av6 |  Av7 |  Av8 |  Asparclet |  Asparclite

 Av8plus |  Av8plusa |  Av9 |  Av9a

Explicitly select a variant of the SPARC architecture.

 Av8plus

and

 Av8plusa

select a 32 bit environment.

 Av9

and

 Av9a

select a 64 bit envi 

ronment.

 Av8plusa

and

 Av9a

enable the SPARC V9 instruction set with UltraSPARC extensions.

 xarch=v8plus |  xarch=v8plusa

For compatibility with the Solaris v9 assembler. These options are equivalent to  Av8plus and

 Av8plusa, respectively.
