* Enable emitting of constant values in non-default address space as well. The ↵Sanjiv Gupta2009-01-302-18/+22
| | | | | | APIs emitting constants now take an additional parameter signifying the address space in which to emit. The APIs like getData8BitsDirective() etc are made virtual enabling targets to be able to define appropirate directivers for various sizes and address spaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63377 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a post-RA scheduling dependency bug.Dan Gohman2009-01-301-0/+5
| | | | | | | | | | | | | | | | If a MachineInstr doesn't have a memoperand but has an opcode that is known to load or store, assume its memory reference may alias *anything*, including stack slots which the compiler completely controls. To partially compensate for this, teach the ScheduleDAG building code to do basic getUnderlyingValue analysis. This greatly reduces the number of instructions that require restrictive dependencies. This code will need to be revisited when we start doing real alias analysis, but it should suffice for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63370 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | 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

Also, factor out code from all 5 of the ReplaceAllUses* functions into AddNonLeafNodeToCSEMaps, which is now renamed AddModifiedNodeToCSEMaps to more accurately reflect its purpose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62964 91177308-0d34-0410-b5e6-96231b3b80d8
* Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, ↵Devang Patel2009-01-232-2/+10
| | | | | | | | | | | | | DW_AT_APPLE_flags. DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way. DW_AT_APPLE_flags encodes command line options when certain env. variable is set.
