M32R Options
------------

   The Mitsubishi M32R version of `as' has a few machine dependent
options:

`-m32rx'
     `as' can assemble code for several different members of the
     Mitsubishi M32R family.  Normally the default is to assemble code
     for the M32R microprocessor.  This option may be used to change
     the default to the M32RX microprocessor, which adds some more
     instructions to the basic M32R instruction set, and some
     additional parameters to some of the original instructions.

`-m32r'
     This option can be used to restore the assembler's default
     behaviour of assembling for the M32R microprocessor.  This can be
     useful if the default has been changed by a previous command line
     option.

`-warn-explicit-parallel-conflicts'
     Instructs `as' to produce warning messages when questionable
     parallel instructions are encountered.  This option is enabled by
     default, but `gcc' disables it when it invokes `as' directly.
     Questionable instructions are those whoes behaviour would be
     different if they were executed sequentially.  For example the
     code fragment `mv r1, r2 || mv r3, r1' produces a different result
     from `mv r1, r2 \n mv r3, r1' since the former moves r1 into r3
     and then r2 into r1, whereas the later moves r2 into r1 and r3.

`-Wp'
     This is a shorter synonym for the
     _-warn-explicit-parallel-conflicts_ option.

`-no-warn-explicit-parallel-conflicts'
     Instructs `as' not to produce warning messages when questionable
     parallel instructions are encountered.

`-Wnp'
     This is a shorter synonym for the
     _-no-warn-explicit-parallel-conflicts_ option.
