So I have dual mode 16/32 compilation on a per function basis working. I need to clean up some things and then will push the change. I managed to do everything without needing to change anything in target independent code thus far. It was a fun puzzle to solve as to how to do this using only the given APIs. As for the BasicTransformInfoPassass, for this dual mode I'm using

...ucture once per module. I would personally choose between these based on how much shared functionality there would be in the TM and TTI between the two. -------------- next part -------------- An HTML attachment was scrubbed...
