If your target CPU does not have a Floating Point Unit (FPU) or a
|
|
kernel FPU emulator, but you still wish to support floating point
|
|
functions, then everything will need to be compiled with soft floating

If your target CPU does support the MIPS16 instruction set

MIPS16 produces smaller binaries thus reducing pressure on

If you're specifying an addition target architecture,

you'll probably need to also provide options to make
|
|
the compiler use this alternate arch.
|

|
|
For example, if you're building a compiler that can build
|
|
both powerpc and powerpc64 binaries, you'll need to
|
|
specify -m64 here.
