PDP-11

These options are defined for the PDP-11:

       -mfpu
           Use hardware FPP floating point.  This is the default.  (FIS
           floating point on the PDP-11/40 is not supported.)  Implies
           -m45.

       -msoft-float
           Do not use hardware floating point.

       -mac0
           Return floating-point results in ac0 (fr0 in Unix assembler
           syntax).

       -mno-ac0
           Return floating-point results in memory.  This is the
           default.

       -m40
           Generate code for a PDP-11/40.  Implies -msoft-float
           -mno-split.

       -m45
           Generate code for a PDP-11/45.  This is the default.

       -m10
           Generate code for a PDP-11/10.  Implies -msoft-float
           -mno-split.

       -mint16
       -mno-int32
           Use 16-bit "int".  This is the default.

       -mint32
       -mno-int16
           Use 32-bit "int".

       -msplit
           Target has split instruction and data space.  Implies -m45.

       -munix-asm
           Use Unix assembler syntax.

       -mdec-asm
           Use DEC assembler syntax.

       -mgnu-asm
           Use GNU assembler syntax.  This is the default.

       -mlra
           Use the new LRA register allocator.  By default, the old
           "reload" allocator is used.
