@item -mlittle-endian
Generate code for a processor running in little-endian mode.
@item -mmedlow
Generate code for the Medium/Low code model: assume a 32 bit address space.
Programs are statically linked, PIC is not supported. Pointers are still
64 bits.
@item -m32
@itemx -m64
Generate code for a 32 bit or 64 bit environment.
The 32 bit environment sets int, long and pointer to 32 bits.
The 64 bit environment sets int to 32 bits and long and pointer
to 64 bits.
It is very likely that a future version of GCC will rename this option.
@item -mcmodel=medlow
Generate code for the Medium/Low code model: the program must be linked
in the low 32 bits of the address space. Pointers are 64 bits.
Programs can be statically or dynamically linked.
@item -mmedany
Generate code for the Medium/Anywhere code model: assume a 32 bit text
and a 32 bit data segment, both starting anywhere (determined at link time).
Programs are statically linked, PIC is not supported. Pointers are still
64 bits.
@item -mcmodel=medmid
Generate code for the Medium/Middle code model: the program must be linked
in the low 44 bits of the address space, the text segment must be less than
2G bytes, and data segment must be within 2G of the text segment.
Pointers are 64 bits.
It is very likely that a future version of GCC will rename this option.
@item -mcmodel=medany
Generate code for the Medium/Anywhere code model: the program may be linked
anywhere in the address space, the text segment must be less than
2G bytes, and data segment must be within 2G of the text segment.
Pointers are 64 bits.
@item -mfullany
Generate code for the Full/Anywhere code model: assume a full 64 bit
address space. PIC is not supported.
It is very likely that a future version of GCC will rename this option.
@item -mint64
Types long and int are 64 bits.
@item -mlong32
Types long and int are 32 bits.
@item -mlong64
@itemx -mint32
Type long is 64 bits, and type int is 32 bits.
@item -mcmodel=embmedany
Generate code for the Medium/Anywhere code model for embedded systems:
assume a 32 bit text and a 32 bit data segment, both starting anywhere
(determined at link time). Register %g4 points to the base of the
data segment. Pointers still 64 bits.
Programs are statically linked, PIC is not supported.
