* Enable the red zone on x86-64 by default.Dan Gohman2009-01-271-1/+1

* Assorted debug info fixes.Devang Patel2009-01-272-18/+20
| | | | | | | | | | - DW_AT_bit_size is only suitable for bitfields. - Encode source location info for derived types. - Source location and type size info is not useful for subroutine_type (info is included in respective DISubprogram) and array_type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63077 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the Red Zone calculation for functions with frame pointers.Dan Gohman2009-01-271-7/+10
| | | | | | | | | Don't use the Red Zone when dynamic stack realignment is needed. This could be implemented, but most x86-64 ABIs don't require dynamic stack realignment so it isn't urgent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63074 91177308-0d34-0410-b5e6-96231b3b80d8

Rather than make the checking more complicated, I've tweaked some logic to make things conform to how the checking thought things ought to be, since this results in a simpler "mental model". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63048 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in BitVector.h. All assignment operations (except the usual Roman Levenstein2009-01-261-3/+3
| | | | | | | | | | assignment operator) were returning a copy of the bit vector, instead of a reference! This old semantics probably did not meet the expectations.

* Take the next steps in making SDUse more consistent with LLVM Use, andDan Gohman2009-01-265-266/+238
| | | | | | | | | | | | | | | | | | tidy up SDUse and related code. - Replace the operator= member functions with a set method, like LLVM Use has, and variants setInitial and setNode, which take care up updating use lists, like LLVM Use's does. This simplifies code that calls these functions. - getSDValue() is renamed to get(), as in LLVM Use, though most places can either use the implicit conversion to SDValue or the convenience functions instead. - Fix some more node vs. value terminology issues. Also, eliminate the one remaining use of SDOperandPtr, and SDOperandPtr itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62995 91177308-0d34-0410-b5e6-96231b3b80d8
