This one isn't a wrong-code issue, just a missed optimization. The strlen
optimizations need to be made to look through ADDR_SPACE_CONVERT_EXPR to
work on ptx.
Bootstrapped and tested together with the other patches on x86_64-linux.
Ok?
Did you try adding ADDR_SPACE_CONVERT_EXPR to the tree codes
handled in gimple_assign_cast_p?
I did now (full test on x86_64, and also tested with ptx), and that also
appears to work. Ok?
