This option specifies the target processor. The assembler will issue an
error message if an attempt is made to assemble an instruction which
will not execute on the target processor.

This option specifies the target architecture. The assembler will issue
an error message if an attempt is made to assemble an instruction which
will not execute on the target architecture.
@cindex @code{-mthumb} command line option, ARM
@item -mthumb
This option specifies that only Thumb instructions should be assembled.
@cindex @code{-mall} command line option, ARM
@item -mall
This option specifies that any Arm or Thumb instruction should be assembled.
@cindex @code{-mfpa} command line option, ARM
@item -mfpa [@var{10}|@var{11}]
@item -mfpa @var{[10|11]}
This option specifies the floating point architecture in use on the
target processor.
@cindex @code{-mfpe-old} command line option, ARM
@item -mfpe-old
Do not allow the assemble of floating point multiple instructions.
@cindex @code{-mno-fpu} command line option, ARM
@item -mno-fpu
Do not allow the assembly of any floating point instructions.
@cindex @code{-mthumb-interwork} command line option, ARM
@item -mthumb-interwork
This option specifies that the output generated by the assembler should
be marked as supporting interworking.
@cindex @code{-mapcs} command line option, ARM
@item -mapcs [@var{26}|@var{32}]
@item -mapcs @var{[26|32]}
This option specifies that the output generated by the assembler should
be marked as supporting the indicated version of the Arm Procedure.
Calling Standard.
@cindex @code{-mapcs-float} command line option, ARM
@item -mapcs-float
This indicates the the floating point variant of the APCS should be
used. In this variant floating point arguments are passed in FP
registers rather than integer registers.
@cindex @code{-mapcs-reentrant} command line option, ARM
@item -mapcs-reentrant
This indicates that the reentrant variant of the APCS should be used.
This variant supports position independent code.
@cindex @code{-EB} command line option, ARM
@item -EB
This option specifies that the output generated by the assembler should
be marked as being encoded for a big-endian processor.

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

This option enables the generation of PIC (position independent code).
@cindex @code{-moabi} command line option, ARM
@item -moabi
This indicates that the code should be assembled using the old ARM ELF
conventions, based on a beta release release of the ARM-ELF
specifications, rather than the default conventions which are based on
the final release of the ARM-ELF specifications.

This is the generic @var{.align} directive. For the ARM however if the

behave as if the argument had been 2 (ie pad to the next four byte
boundary). This is for compatability with ARM's own assembler.
