Title:
ppc: softfloat float implementation issues
Status in QEMU:
Expired
Bug description:
Per bug #1841491, Richard Henderson (rth) said:
> The float test failure is part of a larger problem for target/powerpc
> in which all float routines are implemented incorrectly. They are all
> implemented as double operations with rounding to float as a second
> step. Which not only produces incorrect exceptions, as in this case,
> but incorrect numerical results from the double rounding.
>
> This should probably be split to a separate bug...
