* Lots of improvements to the new dagisel emitter. This gets it toChris Lattner2010-02-211-18/+126
| | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96716 91177308-0d34-0410-b5e6-96231b3b80d8

* Check in the first big step of rewriting DAGISelEmitter to Chris Lattner2010-02-151-0/+217
produce a table based matcher instead of gobs of C++ Code. Though it's not done yet, the shrinkage seems promising, the table for the X86 ISel is 75K and still has a lot of optimization to come (compare to the ~1.5M of .o generated the old way, much of which will go away). The code is currently disabled by default (the #if 0 in DAGISelEmitter.cpp). When enabled it generates a dead SelectCode2 function in the DAGISel Header which will eventually replace SelectCode. There is still a lot of stuff left to do, which are documented with a trail of FIXMEs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96215 91177308-0d34-0410-b5e6-96231b3b80d8
