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
|
||||
point support (-msoft-float).

If your target CPU does support the MIPS16 instruction set

and you want to use it for packages, enable this option.

MIPS16 produces smaller binaries thus reducing pressure on

caches and TLB.

If you're specifying an addition target architecture,

you'll probably need to also provide options to make

the compiler use this alternate arch.

both powerpc and powerpc64 binaries, you'll need to

specify -m64 here.
