[Qemu-devel] [PATCH 0/7] target/ppc: Some cleanups to fp exceptions

Posted by Richard Henderson 7 years ago

There are a few bugs here, primarily wrt usage of GETPC().
But there is opportunity to share more code between paths
that operate on different floating point types.

This is not everything that could be done, but it's a good start.
Better for this not to hang out on a branch for another release.
