Convert H8 port to LRA
With Vlad's recent LRA fix to the elimination code, the H8 can be converted
to LRA.
This patch has two changes of note.
First, this turns Zz into a standard constraint. This helps reloading for
the H8/SX movqi pattern.
Second, this drops the whole pattern for the SX bit memory operations. I
can't see why those exist to begin with. They should be handled by the
standard bit manipulation patterns. If someone wants to try and improve SX
bit support, that'd be great and they can do so within the LRA framework :-)
Pushed to the trunk...
gcc/
* config/h8300/constraints.md (Zz): Make this a normal
constraint.
* config/h8300/h8300.cc (TARGET_LRA_P): Remove.
* config/h8300/logical.md (H8/SX bit patterns): Remove.
