Arnold Schwaighofer [Mon, 22 Feb 2010 16:18:09 +0000 (16:18 +0000)]
Mark the return address stack slot as mutable when moving the return address
during a tail call. A parameter might overwrite this stack slot during the tail
call.

The sequence during a tail call is:
1.) load return address to temp reg
2.) move parameters (might involve storing to return address stack slot)
3.) store return address to new location from temp reg

Lots of improvements to the new dagisel emitter.  This gets it to
the point where it is to the 95% feature complete mark, it just
needs result updating to be done (then testing, optimization
etc).

More specificallly, this adds support for chain and flag handling
on the result nodes, support for sdnodexforms, support for variadic
nodes, memrefs, pinned physreg inputs, and probably lots of other
stuff.

In the old DAGISelEmitter, this deletes the dead code related to
OperatorMap, cleans up a variety of dead stuff handling "implicit
remapping" from things like globaladdr -> targetglobaladdr (which
is no longer used because globaladdr always needs to be legalized),
and some minor formatting fixes.

rename SelectScalarSSELoad -> SelectScalarSSELoadXXX and rewrite
it to follow the mode needed by the new isel.  Instead of returning
the input and output chains, it just returns the (currently only one,
which is a silly limitation) node that has input and output chains.

Since we want the old thing to still work, add a new
SelectScalarSSELoad to emulate the old interface.  The XXX suffix
and the wrapper will eventually go away.
