* Add an out-of-line virtual method for the sdnode class to give it a home.Chris Lattner2006-07-191-0/+4
| | | | llvm-svn: 29192
* Ugly hack! Add helper functions InsertInFlightSetEntry andEvan Cheng2006-06-291-0/+14
| | | | | | | RemoveInFlightSetEntry. They are used in place of direct set operators to reduce instruction selection function stack size. llvm-svn: 28987
* Fix CodeGen/Generic/2006-06-28-SimplifySetCCCrash.llChris Lattner2006-06-281-6/+4
| | | | llvm-svn: 28965
* Add a new ISD::CALL node, make the default impl of TargetLowering::LowerCallToChris Lattner2006-05-161-0/+1

* JumpTable support! What this represents is working asm and jit support forNate Begeman2006-04-221-0/+26
| | | | | | | | x86 and ppc for 100% dense switch statements when relocations are non-PIC. This support will be extended and enhanced in the coming days to support PIC, and less dense forms of jump tables. llvm-svn: 27947

* Don't memoize vloads in the load map! Don't memoize them anywhere here, letChris Lattner2006-04-121-2/+0
