[Qemu-devel] [PATCH 0/5] Added 7 instructions to the tricore target

[Bastian Koppelmann]

Hi,

this series was originally posted by Peer Adelt some time ago[1], but still had 
some problems 
which I tried to fix with this patch set.

The tricky bits here were the FTOUZ and MADD/MSUB.F instructions. The latter 
had the 
problem of not giving back the correct NAN when the result of the add/sub of 
muladd/sub
was invalid. I addressed that by fixing up the value later, which feels hacky. 
I feel
the better solution would be extending softfloat to recognize ADD_NAN's and 
emitting
the correct NAN there. On the other hand it's a change in softfloat for a small 
edge case.

Additionally this patch set adds the UPDFL instructions.

Cheers,
    Bastian
