[meta-bug] fold missing optimizations (compared to RTL)
Last modified: 2012-02-06 19:47:26 UTC
Just a meta-bug for all the missing fold which are missing which are in the RTL version of simplify_*.
Confirmed, there might be others which I had forgot.
Some mentioned here: <http://gcc.gnu.org/wiki/Simplifications>.
Just for the record, I'm not sure about how much it is worth to have fold perform all the various sorts of shift/and simplifications that combine can do.
