Description Paolo Bonzini 2009-03-26 16:23:18 UTC 
With -m1 -mno-expand-cbranchdi any function having a branch on long long is broken.

I think the option can be removed.
Comment 1 Kazumoto Kojima 2009-03-27 01:21:53 UTC 
I'd like to remove that option when the trunk opens for such
changes.

Comment 3 Kazumoto Kojima 2009-05-12 23:08:26 UTC 
Fixed.

FYI, I've confirmed that -mno-expand-cbranchdi is still broken
after r146539 fix of cbranchdi4 and the cond-optab merge.
