Hi,

I refer to the previous message by Juergen, regarding his patch to libgcc.
https://gcc.gnu.org/ml/gcc-patches/2014-08/msg01725.html

As of now, libgcc (of GCC v5.3.0) still has the problem of building support for both soft and hard floats, when there is no support for hard floats by the R5900 (and hence resulting in the generation of recursive functions like extendsfdf2).

That patch doesn't seem to have been committed. I would very much like to help to see it get committed because GCC's support for the R5900 is currently not suitable for PlayStation 2 development; software-floating point emulation is severely detrimental to performance.
What else needs to be done first, before it can be accepted?

Thanks and regards,
-W Y
