But not in the line with the rest of GCC. Really if you cannot get a patch
applied to GCC

To clear up the issues.
1.) libgcc provides a fp emulation based on compiled c functions that is to my
very best knowledge untested for avr and extremely inefficient.
2.) avr-libc provides fp emulation that i

Also libm is not supposed to be overriding stuff in libgcc really, it is only
supposed to be including the C math functions.

Oh no, sorry for the confusion: it *is* a user-supplied library.
Sorry, I now see that I somehow copy&pasted the wron

I know that the current situation for the AVR is suboptimal, there really
are overrides in libm.a for functions that are already present in libgcc.a.
However, this is not so easy to change for a number of logist

Wait the user did say to link against -lm anyways. This comes from the specs.
What kind of wrong math functions are being used anyways? If soft-fp, then you
are to think you can override them in libm.a because tha
