* Do not generate by TableGen the hard-coded standard, target-independent part ofRoman Levenstein2008-05-141-140/+3
| | | | | | | | | | | | | | | | DAG instruction selectors. Introudce a dedicated header file for this part: include/llvm/CodeGen/DAGISelHeader.h TableGen now only generates the include preprocessor directive to include this new header. This is a preparation for supporting multiple implementations of instruction selectors in the future. Reviewed and approved by Evan and Dan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51102 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | CodeGenDAGPatterns, where it can be used in other tablegen backends. This allows the inference to be done for DAGISelEmitter so that it gets accurate mayLoad/mayStore/isSimpleLoad flags. This brings MemOperand functionality back to where it was before 48329. However, it doesn't solve the problem of anonymous patterns which expand to code that does loads or stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49123 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | flags. This is needed by the new legalize types infrastructure which wants to expand the 64 bit constants previously used to hold the flags on 32 bit machines. There are two functional changes: (1) in LowerArguments, if a parameter has the zext attribute set then that is marked in the flags; before it was being ignored; (2) PPC had some bogus code for handling two word arguments when using the ELF 32 ABI, which was hard to convert because of the bogusness. As suggested by the original author (Nicolas Geoffray), I've disabled it for the moment.
