| | | | | | | | | Prototype option to save state in a global instead of as a Constant in the Module. (Turned off, for now, with the on/off switch welded in the off position. You get the idea.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9500 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | and TargetInstrDescriptor::ImplicitUses to always point to a null terminated array and never be null. So there is no need to check for pointer validity when iterating over those sets. Code that looked like: if (const unsigned* AS = TID.ImplicitDefs) { for (int i = 0; AS[i]; ++i) { // use AS[i] } } was changed to: for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) { // use *AS } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8960 91177308-0d34-0410-b5e6-96231b3b80d8

* Convert PhyRegAlloc into a proper pass.Brian Gaeke2003-09-212-132/+98
| | | | | | | | | | | | | | | | | | | | | | | PhyRegAlloc.cpp: Don't include TargetMachine.h or TargetRegInfo.h, because these are provided by PhyRegAlloc.h. Merge class RegisterAllocator into class PhyRegAlloc. Simplify & move ctor, dtor to PhyRegAlloc.h. Make some of PhyRegAlloc's reference members into pointer members, so they can be more easily messed with. MarkAllocatedRegs() becomes a member method, with fewer args. PhyRegAlloc.h: Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare TargetRegInfo forward. Give AddedInstrns the obvious clear() method. Make some of PhyRegAlloc's reference members into pointer members, so they can be more easily messed with. Add prototype for markAllocatedRegs().
