FPU stands for floating-point unit.
msoftfloat stands for modified SoftFloat.
mfdlibm stands for modified fdlibm.
mfdlibm is a derivative thanks to fdlibm-5.3.
Note, it's only for reference of little-known libm's internal.
Note again, any of my modification has no advantage as its runtime behavior.
- No inconsistency
Every time reading code, inconsistency drains the motivation completely.
No one will read like that even if it was really useful/functional.
If you're proud of your modern artistic code styles, go IOCCC.
- No auto-hell
Almost of "./configure && make && make install" take me into auto-hell.
Well-known tools of auto* is just for lame package maintainers.
And I won't take care of any new make-alternatives.
Static Makefie is enough to do for moronic coder like me.
