* Use a linked data structure for the uses lists of an SDNode, just like Roman Levenstein2008-03-263-8/+8
| | | | | | | | | | | | | | | LLVM Value/Use does and MachineRegisterInfo/MachineOperand does. This allows constant time for all uses list maintenance operations. The idea was suggested by Chris. Reviewed by Evan and Dan. Patch is tested and approved by Dan. On normal use-cases compilation speed is not affected. On very big basic blocks there are compilation speedups in the range of 15-20% or even better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48822 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce a new node for holding call argumentDuncan Sands2008-03-214-78/+55
| | | | | | | | | | | | | | | | | | 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. Tested with "make check" and the Ada ACATS testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48640 91177308-0d34-0410-b5e6-96231b3b80d8
