Richard Sandiford 842a1be06c [SystemZ] Extend memcpy and memset support to all constant lengths 
Lengths up to a certain threshold (currently 6 * 256) use a series of MVCs.
Lengths above that threshold use a loop to handle X*256 bytes followed
by a single MVC to handle the excess (if any).  This loop will also be
needed in future when support for variable lengths is added.

Because the same tablegen classes are used to define MVC and CLC,
the patch also has the side-effect of defining a pseudo loop instruction
for CLC.  That instruction isn't used yet (and wouldn't be handled correctly
if it were).  I'm planning to use it soon though.

CodeGen Remove an over-zealous assertion. A pointer type could be illegal if the target is prepared to custom-legalize pointer operands. This assertion was evaluated before the target would have a chance to do so, making it impossible. 2013-08-27 00:28:23 +00:00
